Solidification of alloys is a complex phenomenon arising in many modern experimental techniques and industrial technologies related to casting and surfaces processing. The variation of different conditions of solidification (such as undercooling or cooling rate) gives a possibility to control the morphology and size of crystal structure, which substantially influence physical and chemical properties of alloys. In particular, deep undercooling of alloys below equilibrium liquidus, and eutectics results in rapid solidification and yields materials with improved mechanical, magnetic and electrical properties.

合金的凝固是一种复杂的现象，出现在许多现代实验技术和工业技术与铸造和表面处理。不同的凝固条件（如过冷度或冷却速率）的变化提供了控制晶体结构的形态和尺寸的可能性，这实质上影响合金的物理和化学性能。特别地，低于平衡液相线的合金的深过冷和共晶导致快速凝固并产生具有改进的机械、磁性和电性能的材料。
