Bake Hardening Behavior of Cold-Rolled Dual Phase Steel Sheets

摘要：

Effects of pre-straining, baking temperature and baking time on bake hardening (BH) behavior of cold-rolled dual phase steel were investigated. The results show that the investigated dual phase steel has clear BH behavior, the BH value decreased as the pre-straining increased, increased the baking temperature and prolonged baking holding time can also increase the BH. The mechanics of bake hardening behavior in dual phase steel were discussed, in addition, the effect of pre-staining on tensile strength after baking were analyzed.
