摘要：
Q&P hot stamping is a novel process to produce high strength steel parts with better elongation than the conventional ones. In this paper, recent studies of Q&P hot stamping process are presented. Firstly, the process of the Q&P hot stamping is discussed and a fractional cooling steps strategy is introduced to optimize the procedure. Secondly, several different materials are introduced to test the positive effects of Q&P process, and the suitability of these steels are also discussed. Thirdly, the formability of the hot stamping process is studied, as well as the springback phenomenon and its relationship with process parameters. Finally, microstructure evolution during the Q&P hot stamping process is modelled and discussed.
