ジャーナル フリーIn the course of this paper an additiol study to the former papers (TETSU TO HAGANE, XIX, No. 4 and XX, No. 2) is reported and the results are summerized as follows.
Judging from endurance strength obtained by notched bar fatigue tests, ductile steels have no inferior value to that of hard and brittle ones, while the latters show much sensitiveness for notcheffect proportional to their hardness in spite of the endurance superiority for round and smooth specimen.
The hard steels, on the other hand, decrease their endurance strength very suddenly when some local stress be induced by any reason, the consequence is often proved by occurrance of a crack. It is to be beared in mind. therefor, that the surface finishing of a machine part made of such hard and brittle steel, should especially be fine and complete.
As the most reliable material for crankshaft, 100kg Ni-Cr steel and Ni-Cr-W steel are recommended, because the sensitiveness for notch-effect of these steels show as similar value when tempered at 500°C as that of at 600°C, while the other materials show very much difference between both tempering temperatures.
It is also suggested that almost all crankshaft steels should rather be tempered at about 500°C than at about 600°C in view of endurance properties.抄録全体を表示PDF形式でダウンロード (1817K) -

ジャーナル フリーIt is generally known that the forging temperatures of steels are presumed by their elongations of the tension test at high temperatures. From results of the tension and the impact tests on various heat-treated steels, we see that the elongation of steel changes almost smillarly changed as the impact value. Hence, we measured the impact value of twenty-six kinds of steel at the high temperatures and presumed their forging temperatures from the results.抄録全体を表示PDF形式でダウンロード (495K) -

ジャーナル フリーThe effects of iron on two-phase plain Aluminium-Bronzes have been examined, the conclusion being that Dr. Asado's theory of grain refinement caused by peritectic reaction would not be applied, at least, in wrought α+δ-Aluminium-Bronze. The authors, then, have studied the Mechanical and Chemical behaviors of some known or new special wrought Aluminium-Bronzes. These alloys refered are our "H.B"-Alloy-Series, "Ha 7", D.T.D. 135-Alldy "FA" Alloy and SiliconAluminium-Bronze. The properties of HB-4 (the strongest of all) are as follow;

ジャーナル フリーIncrease of hardness of the ternary alloys-Superduralumin, Sander Alloy, Ealloy-by heat treatment was studied. The highly hardenable alloys were obtained. The mechanical properties of these new alloys were studied, They have very high strength (about 70kg/mmmm2). The report of the study on the new strong light alloy II, which has been improved of its properties, will follow in the near future.抄録全体を表示PDF形式でダウンロード (1088K) -

ジャーナル フリーBoth the Mechanical Properties and the corrosion resistance of Mg-Mn alloys are improved with manganese content up to 2·5% Mn, the effects being however were remarkable on the corrosion resistance. Relating to the mechanical properties, the addition of Zinc up to 4% is more effective than by the addition of Manganese. The effects of quenching and tempering were also studied.抄録全体を表示PDF形式でダウンロード (3100K) -
