Abstract

Abstract: Effects of annealing and rapid cooling processes on the properties and microstructure of C-Mn DP590GA steel were studied.The results show that the R_p0.2 of the tested steel increases with the increase of soaking temperature,and the more significant the increase of R_p0.2 along with the increase of soaking temperature.The elongation of the tested steel increases initially as the soaking temperature increases and decreases afterwards.The strength and plasticity of the tested steel increase and decrease,respectively with the increase of rapid cooling ending temperature.When the soaking temperature of the steel is 820 ℃,the better mechanical properties can be obtained:the R_p0.2 is 400 MPa,the R_m is 625 MPa and the A₅₀ is 25.5%.

Key words: hot dip galvanizing, dual phase steel, annealing process, microstructure, properties
