Results show that the Young's modulus is continuously reduced by hydrogen. It seems to be not the result of hydride formation and damage caused by hydrogen charging, and the decrease of modulus induced by hydrogen and its recovery are reversible entirely. The difference of cohesive energy iamong the specimens charged with various hydrogen contents was measured by ion microprobe mass analyzer. The cohesive energy is found to be significantly lowered by dissolved hydrogen. An explanation of the experimental results may be given by the decohesion theory of hydrogen embrittlement. The Young's modulus decrease of the alloy induced by hydrogen may be attributed at least partly to the lowering of cohesive energy of the lattice, and this study may be considered as a verification of the decohesion theory. 收稿日期: 1986-03-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 万晓景 杨柯 曹名洲 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I3/9 1 Paton, N.E.; Buck, O., Effects of Hydrogen on Behavior of Materials, AIME, New York, 1976, p. 83． 2 Paton, N.E.; Spurling, R.A., Hydrogen Effects in Metals, 1983, p. 269． 3 万晓景;高耕宇;秦荣士;赵吉祥,材料科学进展--纪念李薰逝世三周年,科学出版社出版,1986． 4 Woda, M.; Uemori, R.; Nishikawa, O., Surf.
