It is in good agreement after quite a few examinations on a variety of dual phase steels with different composition and structure. The load transfer from ferrite to martensite and the utility of strength of martensite have been also discussed. 收稿日期: 1984-04-18      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 沈显璞 雷廷权 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1984/V20/I4/271 1 田村今男;友田陽;山岡幸男;金谷三郎;小沢正俊;赤尾明;鉄と鋼,59(1973) ,454． 2 Davies, R.
