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. Furthermore, the rules of change about stress field and velocity field are investigated under different deformation condition. The results of simulation give a better interpretation of the deformation regulation during the semi-solid 60Si2Mn rolling.
