Two-dimensional simulation on the rolling process of semi-solid 60Si2Mn by finite element method

The effect of various process variables on the law of metal flow for semi-solid rolling 60Si2Mn was studied by finite element method. Semi-solid 60Si2Mn can be described as compressible rigid visco-plastic porous material saturated with liquid. In terms of thermo-mechanical coupling condition, the distributions of stress, velocity and temperature were studied using software MARC. The simulation results showthat the rigid visco-plastic model can accurately describe the semi-solid 60Si2Mn rolling process.The great deformation can achieve completely in view of low flow stress of semi-solid slurry.
