研究了氢在材料中的有用作用。结果表明：(A)Cu-3质量%Ti氢化合金的导电性和机械强度同时得到提高。氢化反应在调幅分解温度范围内进行，提高了合金的抗拉强度。(B)对富β的α_(13)+Fe_(β)型Ti-4.5Al-3V-2Mo-2Fe合金进行氢化处理，得到尺寸约为0.3μm的细晶，该合金在923℃下具有高达10,600%的超塑性伸长率。(C)将氢化La(FexSi1-−_x)_(13)化合物的压力诱导磁相变用于磁致伸缩应力传感器。(D)氢处理促进了CuPd纳米合金的有序化和催化活性。
Useful functions of hydrogen in materials are studied. (a) Simultaneous improvements of electrical conductivity and mechanical strength for Cu–3mass%Ti hydrogenated alloy were achieved. The hydrogenation reaction proceeds within the range of spinodal decomposition temperature, and then the tensile strength of the alloy was increased. (b) Hydrogen-treatment for a β-rich α + β type Ti–4.5Al–3V–2Mo–2Fe alloy yields the fine grain with the size of about 0.3 μm. This alloy exhibited the high superplastic elongation of 10,600% at 923 K. (c) Pressure induced magnetic phase transition of hydrogenated La(FexSi1−x)13compounds was applied to magnetostrictive stress-sensor. (d) Ordering and Catalytic activity of CuPd nanoalloys are promoted by hydrogen treatment.
