Abstract：An observation of the deformation and fracture behaviour of low carbonmartensite-ferrite dual-phase steel was performed using SEM with tensile-stage andautograph test machine.It was shown that the microcracks are nucleated at theinterface of martensite/ferrite and along the martensite boundaries of differentorientations,or initiated owing to the fracture of martensite laths under defor-mation of tensile stress.The cracks may propagate by the coalescence of maincrack and the growth of microcracks,then rapidly connect with each other alongthe strong shear deformation zone.Its micro-feature is appeared as the dimplefracture and seems to be of the ductile fracture mechanism. 收稿日期: 1985-05-18      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 张振芳 刘民治 苏会和 徐永波 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1985/V21/I5/56 1 Parker,E.R.,Metall.Trans.,8A(1977) ,1025． 2 邦武立郎;大谷泰夫,日本金属学会会报,14(1975) ,689． 3 牧正志;田村今男,日本金属学会会报,13(1974) ,329． 4 Furkawa,T.,Met.Progr.,116(1979) ,№8,36． 5 Curry,D.T.,Mach.Design,50(1978) ,№16,54． 6 新美格,日本金属学会会报,20(1981) ,678． 7 Kim,N.J.;Thomas,G.,Metall.Trans.,12A(1981) ,483． 8 Lepera,F.S.,J.Met.,32(1980) ,№3,38． 9 徐永波;刘民治;李恒武;苏会和;朱桂秋;金属学报,15(1979) ,367． No related articles found!
