基于多相场模型对Inconel 718合金定向凝固中的柱状晶向等轴晶转变（CET）过程进行了数值模拟，探究了不同温度梯度下CET的凝固组织，研究了等轴晶、柱状晶和混合晶在凝固过程中的枝晶演化规律，并统计了合金体系中Nb和Cr元素沿高度方向的浓度变化。结果表明，温度梯度从400 K/cm减小到10 K/cm，Inconel 718合金的凝固模式从柱状晶组织转变为等轴晶组织。同时，在凝固过程中，Nb在液相中偏聚，而Cr在固相中偏聚。
The CET （Columnar to equiaxed crystal transition） process of Inconel 718 alloy during directional solidification was numerically simulated based on multi-phase field model. The CET solidification structure was explored under different temperature gradients， and dendrite evolution law of equiaxed， columnar， and mixed crystals were investigated. In addition， the concentration variation patterns of Nb and Cr along height direction were also analyzed. The results indicate that the solidification mode of Inconel 718 alloy is converted from columnar to equiaxed crystals as the temperature gradient decreased from 400 K/cm to 10 K/cm. During the solidification process， Nb is segregated in the liquid phase， while Cr is segregated in the solid phase.
