JOURNAL FREE ACCESSIt is generally known that the morphology of unusual crystals such as platelets, spikes and whiskers are greatly affected by the surface and inner structures of metal, purity of metal, reaction temperature, reaction atmosphere and so on. The growth of oxide platelets on the surface of nickel has not been reported, but it appears that oxide platelets would grow under suitable conditions. The following experiment was carried out with the purpose of investigating the effect of the surface and inner structures of metal on the unusual crystal growth of oxide. The specimens were prepared from electrolytic nickel as deposited, as cold-rolled after Ar-arc melting and as annealed. Each group of specimens recieved three different surface preparations before oxidation, (1) polishing with emery paper, (2) polishing chemically and (3) cutting to observe the cutting section. After oxidation, they were observed directly by a transmission electron-microscope and indirectly by the replica method. The results obtained are summarized as follows;
(1) The growth of nickel oxide platelets was found on the surface polished with emery paper and on the cutting section, for each group of specimens. Oxide spikes and whiskers were also found.
(2) Electron diffraction analyses showed the oxidation product to be NiO. Most of the platelets grew parallel to the NiO (111). Platelets growing parallel to the NiO (110) and NiO (112) were also found.
(3) The observation of carbon replica showed that these oxide platelets were not uniformly distributed on the surface of the specimen.
(4) On the contrary, the growth of oxide platelets was not observed on the surface polished chemically. In this case, only oxide protuberances were found.View full abstractDownload PDF (1049K) -

JOURNAL FREE ACCESSIn order to find the fundamental properties of the binary alloys of iron and boron free from carbon in the Fe side, investigations have been made on the microstructure, hardness, relations between transfomation and cooling rate, ageing properties and mechanical properties. The boron content of specimens ranged between 0.002% and 0.2%. The results obtained were as follows:
(1) In both cases of annealing and solution-quenching from 950° to 1200°C, the hardness increased with the boron content. The hardness solution-quenched increased with rise of the solution temperature, but above 1150°C it became nearly constant regardless of the solution temperature.
(2) In Fe-B alloys quenched from the γ-region, the transfomation point—peritectoid reaction temperature—was super-cooled and its degree increased with the boron content.
(3) Microscopic examinations after water-quenching from the γ-region showed that boron caused an accicular structure. Its hardness increased with the boron content and reached Hv 180 at 0.201%B. According to the X-ray diffraction analysis, it was shown that the accicular structure was body-centered cubic and the lattice parameter increased alone. Therefore, this structure was known to be a α-Fe lattice supersatulated with boron. The formation of this structure was closely related to cooling rates, austenitizing temperatures and boron contents.
(4) In Fe-B alloys water-quenched from 880°C in the ferrite region, a slight quench-ageing occurred at room temperature and at 100°C. In Fe-B alloys, which were 10% and 30% cold rolled, boron did not cause any strain ageing at room temperature and at 100°C.
(5) The tensile strength of Fe-B alloys annealed and solution-quenched at room temperature increased with the boron content, but their ductility was deteriorated. The Charpy impact strength decreased with the boron content, most remarkably with more than 0.05% boron.View full abstractDownload PDF (1220K) -

JOURNAL FREE ACCESSA fundamental experiment was carried out to obtain some information on the internal friction and apparent elastic modulus, when lattice defects and voids of the photomicroscopic scale coexist in metals or alloys.
The effects of void-density and of heat treatment after cold working on the strain amplitude dependence of internal friction and elastic modulus were investigated at room temperature with sintered copper powder. (1) The change in bulk density was not observed during heat treatment in the temperature range between 450° and 730°C after pre-sintering at 700°C and mechanical cutting, while the internal friction decreased rapidly from 11×10−4 to 0.69×10−4 and the elastic modulus increased slowly from 3.3×103 to 4.2×103 (kg/mm2). (2) The internal friction decreased from 0.69×10−4 to 0.22×10−4 and the elastic modulus increased from 4.2×103 to 8.3×103 (kg/mm2) with heat treatment at a higher temperature range between 730° and 1000°C, and the bulk density increased from 77.9 to 85.0% during those heat treatments. By an additional heat treatment at 530°C after 28% cold-rolling, (in this state, the dislocation density may be higher than that of the state treated at 1000°C), both internal friction and elastic modulus were increased from 0.22×10−4 to 0.29×10−4 and from 8.3×103 to 11×103 (kg/mm2), respectively. (3) The internal friction was sensitive to the behavior of lattice defects without being subjected to the effect of void-existence; on the contrary, the elastic modulus was more sensitive to voids than to lattice defects. (4) The results of (1) and (2) suggest that both internal friction and elastic modulus of sintered powder can be more or less controlled independently by mechanical and heat treatments.View full abstractDownload PDF (867K) -

JOURNAL FREE ACCESSRecently, austenitic stainless steels are generally used to build up atomic reactors. These steels can suffer stress-corrosion cracking under a certain condition of stress and corrosive environment. On the other hand, the occurrence of some troubles by the stress-corrosion cracking of austenitic stainless steels under unusual conditions have been reported. Specially marine atomic reactors are in danger of accelerating the occurrence of stress-corrosion cracking that results from the repetition of wetting and drying of the reactor wall by cooling water which moves along the rooling of a ship.
So the authors carried out various autoclave tests, with the following results:
(1) Wetting and drying of specimens accelerates the occurrence of stress-corrosion cracking.
(2) Additions of Nb and solution treatment reduce the corrosion rate.
(3) The disolved oxgen, chloride ions of about 5 ppm in water and the surface contamination of specimen augment the stress-corrosion cracking.View full abstractDownload PDF (1524K) -

JOURNAL FREE ACCESSThe mechanical properties of 0∼53%Cr-Fe alloys have been studied after aging at 475°C. (1) A ductile-brittle transition phenomenon is observed under static bending stress. In 25∼30%Cr alloys, the transition temperature is raised with the progress of aging, and passes through room temperature after 20∼50 hr aging, finally reaching about 300°C with further aging. (2) There is a marked difference in the compression work hardening characteristics between the ductile and the brittle states. In the latter state, the work hardening exponent within a low strain range is very high and the yield stress is hardly varied by prolonged aging. (3) The work hardening characteristics are similar to those of body-centered cubic metals at low temperatures.View full abstractDownload PDF (907K) -

JOURNAL FREE ACCESSA new type yield point phenomenon observed when some binary aluminium alloys such as Al-Mg or Al-Cu are deformed at high temperatures above about 350°C has been reported in the previous paper. The present paper is devoted to a detailed explanation of the mechanism which controls the high temperature yield point phenomenon. The proposed theory in this report concerns the viscous motion of dislocations dragging the Cottrell atmospheres around them and the state equation of deformation derived theoretically explains quite well the phenomena observed at high temperatures. In the viscous motion of a dislocation, a fairly larger stress is needed to increase the dislocation velocity. This means that a remarkable yield drop must occur due to the dislocation multiplication during deformation. Comparing the theoretical state equations deduced from the analysis of Cottrell and Jaswan with the experimental stress-strain curves, the increasing process of the dislocation density was calculated. The results have been shown to be quite reasonable.
The stress-strain curves obtained by a rapid change of the tensile speed agree with the theoretical predictions from the strain rate dependence of the dislocation density. Further the theoretical prediction of the critical temperature above which the viscous motion of dislocations dragging solute atmospheres controls the deformation is in good agreement with the critical temperature for the yield point phenomenon determined experimentally, which shows that the approximation of the theory is highly reasonable.View full abstractDownload PDF (2176K) -

JOURNAL FREE ACCESSThis experiment has been performed to obtain the pearlite malleable cast iron with high ductility and strength. From the S curve of white cast iron for commercial black heart iron, the temperature range of the largest transformation velocity is found at about 570°C and it’s nose time is about 5∼6 sec, and therefore the hardenability of this specimen is very inefficient. The transformation products in various heat treatments become harder with decrease of the transformation temperature, while with rise of the transformation temperature they become softer continuously, except in the vicinity of the nose temperature. The structures of transformation products in this continuous range are bainite, high in tensile strength but low in ductility. And by using the white cast iron of these constituents, pearlite malleable cast iron with sufficient ductility and high strength cannot be manufactured owing to the occurrence of a small quantity of ferrite after the first stage of graphitization, even if cooled rapidly.
Therefore, the malleable cast iron with low carbon and high silicon was supplemented with special elements, such as Mn, Cr and Mo, to facilitate the transformation into the white iron structure at the freezing point and the graphitization at the malleablized treatment. By this procedure, the ferrite formation during cooling at the Ar1 point after the first stage of graphitization can be arrested and the hardenability will be improved. As a result, high strength and ductile pearlite malleable cast irons with sorbitic pearlite and spheroidized pearlite can be manufactured.View full abstractDownload PDF (3191K) -

Type A: unstable
Type B: metastable (negative loop)
Type C: metastable (periodic oscillation of external current)
Type D: stable

JOURNAL FREE ACCESSThe natural potential-time curves of 25Cr-Ni(0∼5%)-Mo(0∼3%) steels in a deaerated sulfuric acid solution (50°, 70°C and boil) are measured, and the relations between the type of the polarization curves and their natural potential-time curves and corrosion properties are discussed.
(1) The natural potential-time curves of 25Cr-Ni-Mo steels are classified into four types.
Type A: holds the active potential
Type B: shows a periodic oscillation of the potential from the passive to the active state
Type C: holds the passive potential after active dissolution
Type D: holds the passive potential without any active dissolution
(2) In the immersed test there is a good coincidence among the type of the natural potential-time curves, anodic polarization curves and corrosion properties.
(3) It is concluded that all the steels showing the types C and D in the natural potential-time curves have self-passivation characteristics even in a deaerated sulfuric acid solution without oxidizing agents.
(4) Effectiveness of the potentiostatic polarization method for studying corrosion resistance of these steels was confirmed.View full abstractDownload PDF (1425K) -

JOURNAL FREE ACCESSThe anodic behavior and self-passivation phenomenon of 25Cr steels containing various amounts of Ni and Mo in a 5% sulfuric acid solution were already reported in a previous paper.
In the present experiment the anodic polarization curves of high Cr-Ni-Mo steels with various contents of Cr and Mo were measured in a boiling sulfuric acid solution, and the oscillation of external current was mainly discussed.
(1) The passivation potential shifts to the noble direction in proportion to the acid concentration and to the less noble direction as Cr contents increase, but the tendency is weaker than Mo.
(2) The anodic polarization curves of high Cr-Ni-Mo steels show four types as classified in Report-I in accordance with the acid concentration.
(3) The periodic oscillation of external current is observed at the active state and its period depends on the applied potential.View full abstractDownload PDF (1028K) -

JOURNAL FREE ACCESSThe effects of cold-working and aging temperature on the mechanical properties of Au-Ag-Pt-Pd-Cu alloys and ternary alloys such as Au-Cu-Pd and Au-Ag-Cu, etc. were examined, and simultaneously the age-hardening characteristics of those alloys were investigated by means of X-ray diffraction analyses, microscopic observations and measurements of the physical properties. The results obtained were as follows:
The aging temperatures of the above-described alloys, at which the most excellent tensile strength, hardness and spring properties were obtained were 400°, 370° and 300°C. Their hardnesses obtained at the same time were Vickers-hardness numbers 395, 480 and 260, respectively. It was found by X-ray diffraction and the measurments of the variation of electrical resistance and thermal expansion due to the temperature that those age hardened specimens clearly showed the precipitation and the formation of the ordered-lattices.View full abstractDownload PDF (875K) -

JOURNAL FREE ACCESSCr-containing Vicalloy specimens composed of 2∼4%Cr, 4∼8%V, (6∼12%Cr+V), 52%Co, balance Fe were air-cooled from 1100°C, reduced to 75∼94% by cold working and then subjected to tempering at temperatures between 100° and 800°C. The changes in the saturation induction, residual induction, coercive force, thermal dilatation, electrical resistivity and mechanical hardness of Cr-containing Vicalloy during tempering were determined. The transformation temperature range between heating and cooling is large in Vicalloy containing 9% (Cr+V). By tempering at about 400°C after cold-working, the saturation induction, electrical resistivity and lengths of specimens increase a little larger than those in the cold worked state. It is caused by the ordering of the alpha phase during tempering. The alpha phase is transformed partially to the gamma phase by tempering at 550°∼650°C, so that the electrical resistivity and lengths of specimens decrease and the coercive force increases. When the Vicalloy containing 12% (Cr+V) is tempered at a higher temperature for a short period after cold working, the maximum of coercive force is higher. However, the maximum value of the coercive force of an air-cooled Vicalloy containing 9% (Cr+V) hardly depends on the tempering temperature .View full abstractDownload PDF (758K) -

JOURNAL FREE ACCESSThe plastic strain ratio D, as well as Lankford value R, of a low carbon steel sheet was calculated theoretically by the following procedure: At first, the D-values of certain grains, the orientation of which was defined by α, β, θ, was calculated under some assumption about the tensile deformation of polycrystalline aggregates. On the other hand, the axis density of crystallographic planes defined by α, β were obtained from the inverse pole figure of sheet normal direction. Then the average D-value of polycrystalline sheet can be estimated by the following equation:

JOURNAL FREE ACCESSA transmission electron microscopic investigation has been carried out on the interaction between dislocations and small precipitates at the early stage of ageing of an aluminium-1.42 wt% silicon alloy. From the measurements of the radius of a curvature of dislocations expanded between pinning precipitates, yield stresses have been determined for several cases, the values of which were compared with their theoretical estimations. The results show that dislocations cut through the small precipitates at the early stage of ageing. Main resistances to the motion of dislocations were attributed to the frictional force on the dislocations gliding inside the precipitates, the formation of misfit dislocations, the alteration of atomic arrangements at the surface of precipitates and the frictional force in the matrix. The frictional stress in silicon precipitates was estimated to be about 15∼35×108 dynes/cm2, that is, about G⁄200∼G⁄500. This result shows that silicon crystals, which are brittle at room temperature in ordinary tensile tests are deformed plastically in the form of small precipitates at a relatively low stress.View full abstractDownload PDF (1965K) -

JOURNAL FREE ACCESSA study has been made of the interaction of dislocations and precipitates in an aluminium-1.42 wt% silicon alloy at the stage of maximum strength and over-aged states by a transmission electron microscope technique. The values of yield stress in tensile tests were found to be inversely proportional to the mean planar interparticle spacing in accordance with Orowan’s by-pass mechanism. Observations of dislocation movements in the thin foils showed the by-pass process, the formation of dislocation half-loops around the precipitates lying near the surface and loops sorounding several precipitates, and a tangling of dislocations around the large precipitates. Comparison with the observations on the thin foils which were prepared from the deformed bulk specimens showed that these phenomena might also occur in the bulk materials.View full abstractDownload PDF (1841K) -

JOURNAL FREE ACCESSDomain patterns of large crystals and single crystals of 70.92% manganese-aluminium alloys prepared by the zone melting method were observed microscopically with a colloidal solution of fine iron oxide particles with or without applying the magnetizing field. The domain patterns on the ferromagnetic phase are similar to those of Co and MnBi. From magnetizing curves of the major axes measured at room temperature, the saturation magnetization, 4πIs was found to be 6900 gauss and the crystalline anisotropy constant K of 9.3×106 ergs/cm3 was calculated from the anisotropy field and the saturation magnetization. In cooling from room temperature down to −140°C, 4πIs and K hardly varied, but in heating the both parameters slightly decreased from about 60°C.View full abstractDownload PDF (1235K) -

JOURNAL FREE ACCESSAn investigation was carried out on the corrosion resistance of titanium in hot concentrated chloride solutions, in order to study the cause of the unusual crevice corrosion encountered in chemical plants and to find its preventive measure. The weight losses during the corrosion test and potentiostatic polarization were measured in various chloride solutions at or near the boiling temperatures.
Stability of passivity on titanium was found to be dependent on the chloride concentration: the domain of passivity decreased with increase of the chloride and hydrogen ion concentrations, and the passivity became gradually unstable. And the tendency to activate from the passive state was accelerated by the elevation of temperature. For instance, while no corrosion was observed in the neutral 25%NaCl solution, a severe general corrosion occurred in the acidic 33%AlCl3 solution, and even in the case of a neutral solution, pitting corrosion occurred in such high chrolide concentration solutions as 61%CaCl2 and 86%ZnCl2 solutions. In neutral 42%MgCl2 and 44%NH4Cl solutions, serious crevice corrosion was observed to occur in less than 40 hr at the contact face between titanium and Teflon sheet or two titanium sheet specimens where a large amount of titanium oxides (mainly rutile) precipitated. In such a condition, however, no visible sign of corrosion was observed for the titanium-palladium alloy in the test period of 240 hr except a slight discoloration, and the excellent corrosion resistance of the alloy was attributed to a strong passiviating action of palladium which had been retained and concentrated on the alloy surface in the course of a very slight initial corrosion.View full abstractDownload PDF (1589K) -

JOURNAL FREE ACCESSThe absorption spectra of corrosion products of stainless steels produced in high temperature water (250°∼350°C) or steam (300°∼600°C) were observed in the infrared region from 3 to 30 μ. The spectra were compared with those of referred synthetic oxides of FeCr2O4, NiCr2O4, NiFe2O4, Fe3O4, γ-Fe2O3, α-Fe2O3, Cr2O3 and NiO. The corrosion films produced in degassed pure water or steam indicated the spectra of a mixed spinel crystals of chromite (FeCr2O4 or NiCr2O4) and Fe3O4, and the spectra indicated that the content of chromite increased with increasing temperature. However, the corrosion film produced in undegassed pure water indicated a spectrum of γ-Fe2O3. Although the corrosion film produced in degassed NaCl water also indicated a spectrum of the mixed spinel crystal of chromite and Fe3O4, the corrosion film produced in undegassed NaCl water indicated that of NiFe2O4. On the other hand, the corrosion film produced in degassed KOH water indicated a mixed spectrum of NiO and spinel oxide.View full abstractDownload PDF (1169K) -

JOURNAL FREE ACCESSThe investigation on the transformation of austenite to martensite based on the statistical thermodynamics was carried out using the iron-nitrogen binary alloys containing about 1.8 to 2.8 weight per cent nitrogen. The result of this treatment was compared with that of the iron-carbon binary alloys. The Ms point which was determined microscopically by the Greninger and Troiano method descends with the increase of the nitrogen content and attains room temperature at about 2.2 weight per cent nitrogen showing a complete austenitic structure. Ms points of the iron-nitrogen and iron-carbon alloys containing the same atomic percentage agreed with each other. The T0γ−α′ temperature (ΔFγ→α′=0) of the iron-nitrogen alloy fell nearly parallel to the change in the Ms point with increase of the nitrogen content. On the other hand, the driving force necessary for initiating the martensite transformation increased with increase of the nitrogen content. The effect of carbon on the thermodynamic properties of martensite transformation agreed with the effect of nitrogen. Stabilities of martensites and supersaturated ferrites of the nitrogen- and the carbon-iron alloys were also discussed.View full abstractDownload PDF (1534K) -

JOURNAL FREE ACCESSInvestigations were made on the oxidation of titanium and binary titanium alloys containing 3%Al, 3%Mn, 7%Mn, 3%Fe and 7%Fe, respectively. Oxidation/time curves were measured at 900°∼1000°C in air, and oxidized specimens were examined by X-ray diffraction, electron beam X-ray microanalysis, microhardness and metallographic techniques. Rutile was the only oxide detected on titanium and its alloys under the experimental conditions, but a trace of manganese titanate was observed in the scale of a Ti-7%Mn alloy. The α-phase was found on the rim of underlying metals by dissolving oxygen, but its morphology in titanium alloys oxidized above the transformation temperature differs from that of unalloyed titanium. The hardness gradient, that is, the oxygen gradient was remarkable in the α-band, but not detected in the elongated α-grains. In oxidized samples of Ti-Mn and Ti-Fe alloys, marked manganese and iron enrichments were observed in the β-phase next to the α⁄β interface, but such a enrichment of aluminum in Ti-3%Al alloy was not observed.View full abstractDownload PDF (1728K) -
