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

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-6Al-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-6Al-4V are produced by EBSM, the average of ultimate tensile strength and the fracture elongation of the specimen are 1080MPa and 10.10%, respectively.
