Abstract

The effect of the pre-compression deformation on the mechanical property of dual phase steel DP590 which is developed early and used extensively in automotive industry is investigated in this paper. The tensile performance, the flow curve, strain hardening index and three-point bending strength in different pre-strain condition are measured. The microstructure and tension fracture are observed respectively by using of microscope and by using SEM. The results show that the compression pre-strain 5% then tension deformation, the DP590 has a pronounced Bauschinger effect, but compression pre-strain 5% processing has no effect on the bending strength. The pre-compressive strain 10%, makes Bauschinger effect disappear, and the bending strength is increased. Based on the microstructure, flow characteristics, working hardening characteristics and the stress state analysis under different experiments for the DP590, the relevant experimental results are clarified.
