摘要
综述了相场模型在模拟合金定向凝固过程中的应用。将合金定向凝固中的两个重要参数(生长速度和温度梯度)从理论角度计算得到的数值应用在模拟过程中,把模拟结果与理论结果进行对比得到结论,同时在模拟过程中采用温度冻结近似以简化计算。
This paper reviews the phase-field simulation on directional solidification for alloys. During simulation, a great number of people have been used these tow important parameters, the growth and temperature gradient, which were calculated in the theory, then compared the results of simulation with the theoretical conclusion. The validity of frozen temperature approximation could simplify the calculation in phase-field model in simulation.
