ジャーナル フリーBy means of a resonant-bar technique combined with an accoustic level recorder, the effect of ICl doping on the amplitude-indpendent internal friction and dynamic elastic modulus of a reactor grade polycrystalline graphite has been investigated at temperatures between 200°K and 375°K. The intercalation of ICl was conducted in a stepwise manner to 0.06, 0.09, 0.16 and 0.19 atomic per cent respectively. In the internal friction vs. ambient temperature diagram, a characteristic peak has been found to grow up nearby 250°K on the ordinate, with the increase of ICl concentration; which is likely common with those observed by Tailor-Kline-Walker on other specimens. However, the present study has revealed that the anelastic natures of this peak contradict those of the socalled Bordoni peak. Brief discussions are given on some possible mechanisms.抄録全体を表示PDF形式でダウンロード (477K) -

ジャーナル フリーDiffraction intensities of (002) line were measured on six kinds of cokes, five petroleum cokes and polyvinyl-chloride coke PV-7, and a thermal black. The observed diffraction intensity was corrected for Lorentz-polarization factor, absorption factor and square of atomic scattering factor, and then normalized to a given experimental condition by using the diffraction intensity of polyethylene which was placed in the front of carbon specimen.
The samples except thermal black were impossible to be differentiated from each other by co-spacing, crystallite size, and strain deduced from half-width of diffraction lines. However, the samples used could be clearly distinguished from the diffraction intensity of (002) line. The difference in diffraction intensity seemed to be mainly due to the difference in the degree of preferred orientation of graphite-like layers in the specimen for X-ray, reflected from the texture of the coke and thermal black.抄録全体を表示PDF形式でダウンロード (517K) -
