摘　　要：综述了喷射沉积材料的半固态成形的研究进展和发展趋势,分析了喷射沉积材料的半固态成形工艺、半固态变 形特征和半固态成形的加热和保温过程中组织演变规律,提出高固相率的触变成形是喷射沉积材料半固态成形的发展方 向。This paper has summarized the present status and future development of semisolid forming of spray deposition alloys. Analyse the method of semisolid forming of spray deposition materials, the characteristic semisolid deformation of spray deposition materials and evolution of microstructures during semisolid forming. Propound that thixo-forming under high solid volume fraction is the developmental trend of semisolid forming for spray deposition alloys.
