The methane bub-bles were formed preferentially along grain boundaries and twin boundaries, and some ofthem in grains. Experimental results and thermodynamical analysis indicated that the Cr-de-pleted region around bubbles is not necessary condition in growth stage of bubbles. Key words： hydrogen attack    austenitic stainless steel    methane bubbles    Cr-depleted region 收稿日期: 1993-04-18      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 李晓刚 陈华 姚治铭 李劲 柯伟 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1993/V29/I4/73 1 Inglis N P, Andrews W J.
