The results indicate that both structure and properties of martensite and ferrite phases are quite different from those of single-phase ones. The conventional mixture law, which is commonly used to evaluate the strength of the fibre-reinforced composite materials seems to be not applicable. The model of deformation of the dual phase steel 20 in the process of cold rolling may be proposed by a gradual transition from stress-equal model at the starting to strain-ratio-equal model on the later stage. Its work-hardening may be attributed to a change from nonequal strengthening state to strength-ratio-equal state A summarized plot for its deformation behaviour during cold-rolling is also given to understand rather easily the relative variation of the structure and properties of each phase in the whole process. 收稿日期: 1982-01-18      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 雷廷权 沈显璞 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1982/V18/I1/75 1 Rashid, M.
