摘要
The concentration field and temperature field of solidifying crystals in the,processing of semi-solid metals were analysed under stirring condition. By using solidification velocity and flow speed of the melt as variations of affecting the shape of crystals, a shape determination model for grain growth was developed under the condition of moving liquid. The morphologies of grain growth under different conditions of semi-solid processing were simulated. The simulation results are in accord with the experimental results.
