摘要：

对20碳钢/316L不锈钢复合材料在Gleeble-3500热模拟试验机上进行了热压缩试验，并结合DEFORM3D有限元软件分析了应变变化趋势和微观结构演变规律，建立了其Arrhenius本构模型。试验过程中碳钢体积占2/3,不锈钢体积占1/3,应变速率为0.1~10 s-1，变形温度为1000~1100 ℃。通过比较模拟和试验结果，发现碳钢与不锈钢双金属材料的应力-应变曲线与试验结果存在一定的比例关系而且复合材料中间区域的变形量大于两端。通过模拟可得出整体过程中不锈钢的平均晶粒比碳钢大。由于试验结果跟模拟结果存在一定的差别，在物块外表面不能明确看出物体内部是否存在变化，因此本模拟是有必要的。

For the 20 carbon steel/316L stainless steel composite material, the hot compression test was conducted by Gleeble-3500 thermal simulation testing machine combined with finite element software DEFORM-3D, the strain change trend and microstructure evolution laws were analyzed, and the Arrhenius constitutive model was established. During the test, the volume of carbon steel accounted for 2/3, the volume of stainless steel accounted for 1/3, the strain rate was 0.1-10 s-1, and the temperature was 1000-1100 ℃. By comparing the simulation and test results, it is found that there is a certain proportional relationship between the stress-strain curves of carbon steel and stainless steel bimetallic materials and the test results, and the deformation amount in the middle region of the composite material is greater than that at both ends. Through the simulation, it can be concluded that the average grain size of stainless steel is larger than that of carbon steel during the overall process. Due to certain differences between the test results and the simulation results, whether there is a change inside the object cannot be clearly seen on the outer surface of the object. So this simulation is necessary.
