Three different structures ,of them: bainite, tempered martensite and F/M dual-phase revealed after heat treatment. Using the data of the delayed failure and fracture mechanics tests, the σ_n/σ_(bn) vs t_f and da/dt vs K were plotted. The experimental results showed that the best susceptibility to hydrogen embrittlement resistance is the structure of isothermal bainite, the worst one is of tempered martensite and F/M duai-phase structure is obviously reduced the hydrogen induced cracking tendency. 收稿日期: 1987-03-18      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 宋余九 齐民 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I3/205 1 Newman J F, Shreir L L.
