Study on Continuous Annealing Process and Properties of 1180MPa Grade Cold Rolled and Hot Dip Galvanized Dual Phase Steel
This paper dealt with continuous annealing process and mechanical property of a 1180MPa grade cold rolled and hot-dip galvanized dual-phase steel.The effects of process parameters,including annealing temperature and time as well as galvanizing temperature on microstructure and mechanical property of the steel were investigated.It was found that the annealing temperature has the most important effect on mechanical property of the steel.With the increase of annealing temperature,the tensile strength (TS) decreased first and then increased,but the effect of yield strength (YS) and elongation is not obvious,and the annealing time has no significant effect.In addition,YS and TS can be enhanced by increasing galvanizing temperature.
