【摘要】 本工作采用超高真空气相氢渗透技术,在140—400℃温度范围内,测定了氢在纯 Ni(不同冷变形量)中的渗透率、扩散系数和溶解度常数,研究了冷加工对氢渗透和扩散行为的影响。结果指出,在实验温度范围内,氢在纯 Ni 中的渗透率和扩散系数均遵循 Arrhenius 方程,纯 Ni 的冷加工对氢渗透和扩散行为没有明显影响。更多还原

【Abstract】 Permeability,diffusivity and solubility of hydrogen in different cold deformednickel have been measured by gaseous permeation technique over the temperature range of 140to 400℃.The effects of cold working on hydrogen permeation and diffusion have been investi-gated.The results indicated that permeability and diffusivity of hydrogen in pure nickel over theexperimental temperature range follow Arrhenius equations and hydrogen permeation and dif-fusion behaviour are not obviously influenced by cold-work of pure nickel.更多还原
