The type of carbide in decomposition products is related to the distribution and morphology of retained austenite. The ε-carbide may precipitate along the austenite side of martensite/austenite boundary. 收稿日期: 1986-04-18      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 钟炳文 宋宇文 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I4/11 1 Thomas.
