Abstract
In this paper, the law of austenitic grain growth gfg is studied under different heating temperature and insulation time, the suitable grain growth model is established, and the regression calculation method is introduced to verify the correctness of the model. The effect of quenching temperature on the microstructure and strength of steel was studied, and it was proved that the quenching temperature had a significant effect on the microstructure and mechanical properties of Q1030 steel. At the quenching temperature of 880°C - 950°C, with the increase of austenitizing temperature, the hardness and strength of Q1030 steel gradually increased, reaching the maximum value at 950°C. During quenching at 950°C - 1100°C, the hardness and strength of Q1030 steel gradually decreased with the increase of austenitic temperature.
