摘要
采用Gleeble-3800热模拟实验机对铸态50Cr5MoV钢进行热压缩实验,研究其在变形温度为900℃、950℃、1 000℃、1 050℃、1 100℃和应变速率为0.01 s-1、0.1 s-1、1 s-1条件下的动态再结晶行为。结果表明:铸态50Cr5MoV钢在热变形过程中发生了动态再结晶,且随着应变速率的降低以及变形温度的升高,动态再结晶越容易发生。
By using Gleeble-3800 thermomechanical simulator, the hot compression test for as-cast 50Cr5MoV steel has been carried out. Under conditions of the deformation temperature of 900℃, 950℃, 1 000℃, 1 050℃ and 1 100℃and the strain rate of 0.01 s -1 , 0. 1 s -1, 1 s -1, the dynamic recrystallization behaviour of steel has been studied. The results show that the dynamic recrystallization appears during the hot deformation process of as-cast 50Cr5MoV steel. And the dynamic recrystallization is more likely to appear along with the reducing of the strain rate and the increasing of the deformation temperature.
