中文摘要：
对97#钢板进行了热冲压实验研究,分析了不同奥氏体化温度、奥氏体化时间、保压时间对工件组织及力学性能的影响。结果表明,奥氏体化温度950℃、奥氏体化时间5min、保压时间60s为较优工艺参数,抗拉强度达2203MPa,强塑积为18.7GPa·%,金相组织为马氏体。
英文摘要：
Hot stamping process for 97# steel sheet was studied by experiment. The influence of austenitizing temperature, austenitizing time on and pressing microstructure and mechanical property were analyzed. The results show that the optimal processing parameters are austenitizing temperature 950℃, and the austenitizing time 5 min and the pressing time 60s. Mechanical properties of the workpiece are that the tensile strength is 2203MPa, and strength-ductility is 18.7GPa·% ,and the microstructure is martensite.
