| 摘 要： | 采用单道次压缩试验，研究了变形温度和变形速率对SS400钢热变形行为的影响．在此基础上确定了SS400钢Z-Hollomen参数方程，并建立了计算流变应力的模型．通过此模型计算了试验钢的流变应力，确定了动态软化过程激活能为290kJ／mol．结果表明预测结果与实测值吻合良好．

| Abstract: | Effects of SS400 steel's deformation temperature and strain rates on its deformation behavior was studied using single pass compressing test.On this basis,Z-Hollomen parameter equation for SS400 steel has been determined and its flow stress model set up.Flow stress of SS400 steel was calculated using this model.It is shown that the predicted results were in good accordance with measurements. |
