摘要：

In the paper, a typical part of B1500HS boron steel was formed using the hot stamping tools, and the effect of austenitization temperature on the microstructure and mechanical properties of B1500HS boron steel was studied. The results show that, the temperature of steel plate has a significant effect on the temperature of hot stamping tools, and the temperature of punch rises at a faster speed than that of die in the hot stamping process. The austenitization temperature has a significant effects on the size of martensite. The cooling rate of steel plate has a significant effect on the tensile strength when the austenitization temperature is 870 degrees C. The fracture of sample austenitized at 870 degrees C or 900 degrees C is the dimple, the fracture of sample austenitized at 930 degrees C or 960 degrees C is the mixture of quasicleavage and dimple.
