本文综述了金属和合金快速凝固的几个基本方面。介绍了快速凝固过程中冷却速率的不同测量方法，并根据不同的冷却模型对所测得的冷却曲线进行了分析。还描述了快速凝固条件对凝固点附近的传热系数和冷却速率的实验影响，并比较了不同快速凝固工艺的效率。测量过冷度和形状的凝固停止分析根据各种模型的成核和生长在凝固过程中，冷却速度和过冷度的影响，如晶粒尺寸，枝晶臂间距，偏析程度的重要微观结构特征进行了讨论。
This paper reviews several fundamental aspects of the rapid solidification of metals and alloys. Different methods of measuring cooling rates during rapid solidification are described, and the observed cooling curves are analysed according to various cooling models. The experimental effects of rapid solidification conditions on heat transfer coefficient and cooling rate in the vicinity of the solidification point are also described, and the efficiencies of different rapid solidification processes are compared. Measured undercoolings and the shape of the solidification arrest are analysed according to various models of nucleation and growth during solidification, and the effects of cooling rate and undercooling on important microstructural features such as grain size, dendrite arm spacing, and extent of segregation are discussed.
