摘　　要：半固态金属浆料成形是通过控制金属材料在固—液共存状态下所特有的流变特性而进行成形的一种金属制备技术。半固态浆料中的固态初生晶粒有优良的流动性,可以采用挤压、压铸和模锻等加工方法制备产品,半固态浆料成形技术是一种节能、高效的生产加工技术,应用前景广阔。综述了半固态浆料制备技术出现以来的研究成果,包括半固态浆料的成形机理、半固态成形的条件和晶粒细化控制机理等,并对半固态浆料制备技术进行了展望。The semi-solid metal slurry forming is a kind of metal preparation technology which by controlling the solid- liquid coexistence of rheological properties and forming in the process of the metal solidification. The solid primary grain of the semi-solid slurry has good mobility, can preparation products through the processing methods of extrusion, die casting, die forging, Semi-solid slurry forming technology is a kind of energy-saving and efficient production and processing technolo gy and have broad prospects. The research achievements of semi-solid slurry preparation technology is reviewed, including forming mechanism of semi-solid slurry, semi-solid formation conditions and mechanism of grain refinement control and so on, and commented the semisolid slurry preparation technology.
