The steady-state threshold stress for HSSCC in the temperature range of 300—420℃ was found to be lower than their creep strength at the same temperature. The post-exposure ductility of the specimens after HSSCC is susceptible to the strain rate. By ion microproble analysis, results show that hydrogen is markedly concentrated along the fractographic surface. It seems that the hydrogen produced halide salt corrosion and subsequently absorbed by the titanium alloy is responsible for cracking. 收稿日期: 1982-03-18      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 虞炳西 张绥生 万晓景 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1982/V18/I3/264 1 Petersen, V.
