Research on Forming Technology of Electron Beam Selective Melting for Ti-6Al-4V Powder

摘要：

　　Electron beam selective melting (EBSM) has many advantages for the titanium alloy parts manufactured,therefore,the material characteristics,scanning methods and the tensile properties of Ti-6A1-4V by EBSM are studied in this paper.Aimed at the lower density,poorer electric and heat conductibility of Ti-6Al-4V,three scanning paths have been developed:reverse scanning,interlaced reverse and orthogonal scanning,and the surface of forming part made by the above three scanning methods is smooth and no bulge.The tensile specimens of Ti-6A1-4V are produced by EBSM,the average of ultimate tensile strength and the fracture elongation of the specimen are 1080MPa and 10.10%,respectively.
