The experi-mental results are believed to support the authors' previous prediction that thedistribution and shape of the catbides affect obviously the susceptibility of HSLAsteel to hydrogen embrittlement. The measurement of apparent diffusion coeffi-cients of Q+T and N+T specimens revealed that the values of D increased withthe increase of tempering time, suggesting that the density of traps was reduced. 收稿日期: 1985-06-18      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 胡玉和 李凤亮 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1985/V21/I6/33 1 Hirth.
