摘　　要：概述了半固态金属加工制浆工艺的发展以及研究现状,介绍了具有代表性的几种半固态加工技术及其相应的制浆技术,总结了强制对流条件下非枝晶组织的形成机制。流程简洁、成本低廉的流变成形工艺路线成为当前的发展方向,形成具有高密度晶核的半固态浆料是获取高质量半固态加工部件的必要条件。Research and development of semisolid metal slurry processing technology was outlined; and a few representative SSM （semisolid metal processing） methods and the corresponding slurry processing technologies were presented; moreover, the formation mechanism of non-dendritic microstructure under coerced convection condition was summarized. The rheoforming route, whose process flow was simple and prime cost was low, has become the development direction at present. The necessary condition of manufacturing high-quality semisolid processed parts is that the supplied semisolid slurry has high density of nuclei suspending uniformly in the bulk melt.
