摘要：

The microstructure and mechanical properties of the continuous annealing DP590 steel produced by a cold rolled plant were studied by utilizing a Gleeble thermal simulator tested machine. The results show that, increasing annealing temperature can not effectively improve the martensite content in the steel and annealing temperature be set at 780 degrees C and 800 degrees C is rational. Martensite decomposition at high overaging temperature will decrease tensile strength of the samples. As the overaging temperature sets at 250 degrees C similar to 300 degrees C, the samples could achieve tensile strength more than 600 MPa, which meet the requirements of DP590.
