Results indicated that the structure is consisted of fine acicular martensite and ultrafine grained austenite. The carbon content of austenite is about 1.8%, that can also be transformed into fine acicular martensite when cooled in liquid nitrogen. 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 李章 胡建东 房为捷 吕健 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I3/299 1 葛云龙,胡壮麒,高薇.物理,1984;13:385 2 Chen C H, Altstetter C J, Rigsbee J M.
