Effect of intercritical annealing temperature on formability and bake-hardening-index of high strength steel for exposed auto body

摘要：

　　The theoretical prediction of main strengthening elements,final hot rolling,coiling and intercritical annealing soaking temperature were conducted by thermodynamic calculations,which agreed with the experimental results.The good formability and bake-hardening-index property gained from the experimental procedure according to the calculations show that,n (tensile strain hardenability value),r (plastic strain ratio) and BH2 (bake-hardening-index) represent maximum value when soaking temperatures were set from 800 to 820℃,the maximum value ofn is 0.21,r is 1.39,BH2 is 44 MPa.
