Abstract

The spring-back properties were analyzed for a comparison between the TRIP/TWIP (Transformation induced plasticity/Twinning induced plasticity) steel and the DP800 (dual phase) steel. The results showed that the spring-back amount of the steels was influenced importantly by the bending radius and the nominal tension force. The spring-back angle of the TRIP/TWIP steel was bigger than that of the DP800 steel when the R (bending radius) was 9.6 mm, at the same time the nominal tension force was not more than 0.66, and the nominal tension force was more than 0.66, the spring-back angle was smaller than that of the DP800 steel. The spring-back angle of the TRIP/TWIP steel was bigger than that of the DP800 steel when the R (bending radius) was 12.7 mm, at the same time the nominal tension force was not more than 0.73, in the same way, its spring-back angle was relatively small when the nominal tension force was more than 0.73. The spring-back angle of the TRIP/TWIP steel had little difference relative to that of the DP800 steel when the nominal tension force reached 1.0. The big die radius should be set in the stamping process, and the spring-back amount would be decreased.
