Research on Q&P Process and its Springback Property of High Strength Steel

In this paper, the contents mainly include two aspects, one of which is the study of Q&P parameters effects, the main parameters are quenching temperature, partition temperature and partition time. Several groups experiments are carried on under different conditions, the results are determined by the tensile strength and elongation rate which are obtained by tensile test. The second is to carry out experiments on U shaped parts in the same conditions respectively with the traditional hot forming-quenching process and Q&P process, comparing the effect of Q&P and traditional hot forming process on springback, the results of springback are evaluated by the rebound angle. Finally, by analyzing and summarizing the experimental results, finding that Q&P process has little influence on springback.
