With the help of the modified Crussard-Jaoul (C-J) analysis, the effects of soft phase (ferrite) content and its grain size on the work--hardening behavior of the steels and the cooperative deformation relationship between softer phase and harder phase were studied, which was validated by EBSD analysis. The results illustrate that a reasonable proportion of F/B can be helpful to improve initial work-hardening (a high Rt1.5/Rt0.5), reduce the yield ratio, and maintain a high uniform elongation. It is known that the cooperative deformation of ferrite and bainite is the main mechanism for improving the stress ratio and the uniform elongation of the F/B dual-phase steels. 收稿日期: 2011-10-09      基金资助: 国家重点基础研究发展计划资助项目2010CB630801 作者简介: 聂文金, 男, 1978年生, 博士生 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 聂文金 尚成嘉 关海龙 张晓兵 陈少慧 44.8K 链接本文: https://www.ams.org.cn/CN/10.3724/SP.J.1037.2011.00634      或      https://www.ams.org.cn/CN/Y2012/V48/I3/298 [1] Li H L, Li X, Ji L K.
