摘　　要：快速凝固技术得到的合金具有超细的晶粒度,无偏析或少偏析的微晶组织,形成新的亚稳相和高的点缺陷密度等与常规合金不同的组织和结构特征,对材料科学及其它学科的理论研究以及满足实际生产中的需要起到了重大的作用。本文详细总结了最基本和目前最新型快速凝固技术的原理、方法以及特点,介绍了快速凝固技术在买际中的应用状况,阐明了快速凝固技术的发展趋势。Alloys produced by fast solidification have superfine grain size, no or less segreation microstructure, new metastable phase, a high density of microvoids and so on. They have different structure characters compared with general alloys. It is important for fast solidification to develop theoretical research of material science, other subject and meet practical needs. The basic and up-to-date theory, method and characters of fast solidification are summarized in detail. The practical application of fast-solidification and its developing tendency are introduced.
