摘　　要：应用单辊搅拌技术 (也称SCR技术 -Shearing CoolingRollProcess)制备出的A2 0 17半固态材料比常规铸造坯组织优良 ;SCR技术制备的A2 0 17半固态材料在 5 3 0℃～ 5 70℃范围内 ,可获得球形晶粒组织 ,可以进行半固态轧制成形 ;A2 0 17半固态材料触变过程分为四个阶段 ,在稳定触变阶段 ,并在 64～ 72 %的最大加工变形范围内 ,A2 0Microstructures of material manufactured by SCR process is finer than that of conventional casting slab;when semisolid slab was reheated at 530～570℃,spherical micros truces was obtained and semisolid slab manufactured by SCR process can be semisolid rolled.Thixoforming process of A2017 material was divided into four steps.Within steady period of thixoforming process and maximum deformation rate of 64～72%,A2017 semisolid material forming property was fine.
