| 摘 要： | 在研究了一系列定向凝固温度分布的数学模型的基础上，以ZL101合金为研究对象，对前人所提出的固液界面温度场模型，进行了最小二乘优化，将其进行了数值模拟，并进一步推导了在不同温度下，距离状态点的过冷度表达式，通过此表达式可以预测各状态点的过冷度情况，并分析与过冷度相关的一些金属学参量。

| Abstract: | Based on the study of a series of mathematical models of directional solidification temperature field, ZL101 alloy is studied by using least square law; hence, the S-L interface temperature field which is put forward by predecessors is optimized and the model is developed by mathematical simulation. Furthermore, a supercool formula with different state of temperature and distance is deduced.By the formula, every state of supercool can be predicted and some metallurgy parameters can also be analyzed . |
