The model of hydrogen diffusion formerly de- veloped [1] has been applied successfully to the hydrogen permeation experiment results of three kinds of materials,α—Fe,Fe—Ti alloy and Fe—Ti—C alloy by the mathematical fitting method.From the fitting results it was shown that the model can re- fiect we...

Permeability and diffusivity of hydrogen in Fe-Ni-Co based superalloy lncoloy 903 were measured over the temperature range of 220 to 420℃ using a gaseous permeation technique. The effect of strengthening phase γ' precipitated after being aged on the hydrogen permeation and diffusion was investigated...

采用TDS方法研究了氢在两种马氏体钢中的扩散行为,结果发现氢在高铬低铝的D2钢中的扩散显著低于低铬无铝的D1钢。从充氢试样室温放置时氢体积分数下降规律可知,氢在D1钢和D2钢中的扩散系数分别为1.52×10-7和5.3×10-8cm2/s。D2钢中存在大量细小的碳化物,既对氢的扩散起到阻碍作用,降低...

通过TDS方法研究了氢在18Cr2Ni4W和25CrNi2MoVNb两种低温回火马氏体钢中的扩散行为,同时结合慢应变速率拉伸实验研究了这两种马氏体钢的氢脆敏感性。结果表明,与18Cr2Ni4W钢相比,25CrNi2MoVNb钢因碳含量较高和晶粒显著细化作用使抗拉强度从1300MPa级提高到了1500...
