摘要： 采用多孔材料的几何模型，利用MARC软件对弹簧钢60Si2Mn半固态轧制进行了有限元模拟，分析了在热力耦合条件下，将半固态材料视为可压缩的刚-粘塑性体时的应力场、速度场、温度场的状况，由此所进行的模拟工作较好地反映了半固态轧制过程中金属的变形规律。

Abstract: With a geometrical model of porous material, a finite-element analysis on the rolling process of 60Si2Mn in the semi-solid state is carried out using software MARC .In terms of thermo-mechanical coupling condition, the semi-solid materials are regarded as compressible rigid visco-plastic model, then the stress field, velocity field and temperature field are studied. The result of simulation gives a better interpretation of the deformation regulation during the semi-solid 60Si2Mn rolling.
