对不同生产工艺下冷轧态及退火态65Mn钢带的组织和退火态钢带的力学性能进行了分析。未经退火的65Mn钢冷轧时,珠光体组织以弯曲变形为主,随着总变形率的增加,珠光体弯曲变形减少,片层细化变形成为主要变形方式;经预退火的65Mn钢冷轧时,珠光体组织变形均以细化变形为主。采用原料经预退火后再进行冷轧的工艺生产的65Mn退火钢带组织均匀,力学性能稳定,塑性较好。
對不同生產工藝下冷軋態及退火態65Mn鋼帶的組織和退火態鋼帶的力學性能進行瞭分析。未經退火的65Mn鋼冷軋時,珠光體組織以彎麯變形為主,隨著總變形率的增加,珠光體彎麯變形減少,片層細化變形成為主要變形方式;經預退火的65Mn鋼冷軋時,珠光體組織變形均以細化變形為主。採用原料經預退火後再進行冷軋的工藝生產的65Mn退火鋼帶組織均勻,力學性能穩定,塑性較好。

The microstructure of 65Mn cold-rolled hardened and annealed strips and mechanical properties of annealed strips in different production process are studied. The main deformation form of pearlite is bending deformation when the raw material of unannealed 65Mn is cold rolled. Along with the increasing of total deformation rate, the pearlite bending deformation decreases and pearlite lamellar refinement becomes the main deformation form. The main deformation form of pearlite is lamellar refinement when the raw material of annealed 65Mn is cold rolled. Annealed 65Mn strips produced by the process of cold-rolling after raw materials annealed have uniform microstructure,steady mechanical property and preferable plasticity.
