摘要：

The hydrogen-induced volume expansion, a change in the X-ray diffraction first peak due to hydrogen charging and the hydrogen Gorsky effects were measured for amorphous (a-) Cu50Zr50 and Cu50Ti50 and discussed together with the hydrogen Snoek peak reported. The hydrogen-induced Volume expansion is similar between a-Cu50Zr50 and a-Cu50Ti50. In contrast, anisotropy of the elastic distortion around hydrogen appears to be much larger in a-Cu50Zr50 than in a-Cu50Ti50. It is surmised that the local atomic structures are more deformable in a-Cu50Zr50 than in a-Cu50Ti50. (C) 1999 Acta Metallurgica Inc. Published by Elsevier Science Ltd. All rights reserved.
