| 摘 要： | 采用压缩实验法在Gleeble-1500热模拟实验机上测定了33Mn2V钢在恒定温度和恒定速度下的变形抗力.研究结果表明:33Mn2V钢热变形的流变应力随温度的升高和应变的增大而减小.以Kumar本构模型为基础建立了33Mn2V钢热变形的本构方程,同时也通过本构模型计算值与实验所得的数据进行比较,表明该模型能够满足工程应用精度.

| Abstract: | The flow stress of 33Mn2V was measured by upset tests of cylindrical samples in the Gleeble-1500 heat stimula-tion machine.The results showed that the flow stress decreased with the increasing of the deformational temperature and the strain.The Kumar model was verified by comparing the values of calculated with those measured inlaboratory conditions.And it showed that the Kumar-type constitutive relationship meets the practical needs. |
