摘要: ＧＨ７１８合金氢渗透特性的研究徐坚，孙秀魁，刘清泉，陈文绣（中国科学院金属研究所，快速凝固非平衡合金国家重点实验室沈阳１１００１５）１前言ＧＨ７１８（ＩＮＣＯＮＥＬ７１８）合金广泛用作为涡轮叶片、氢燃发动机、核反应堆器壁等部件的材料．由于使用环境中氢气氛的存在，选材时必须考虑氢的进入与传输对合金性能的影响．尽管此合金的氢渗透数据曾有报导山，但关于合金的组织结构对氢渗透和扩散特性的影响仍不十分?...

Abstract：In the present work, the hydrogen permeability and diffusivity of GH718 alloy in several conditions of heat treatment were derermined using a gaseous hydrogen permeation technique. Measurements were made over the temperature range of 210 to 430 ℃. It was shown that the dependence of hydrogen permeability and diffusivity. on temperature of GH718 alloy followed Arrhenius relationship over the experimental temperature range and that the characteristics of hydrogen permeation and diffusion were not sensitive to the forostructure variations of this alloy, namely, the pprecipitation- strengthening phases γ'and γ＂in the alley did not have a pronounced effect on the hydrogen permeation and diffusion behaviour.
