RESEARCH ON LASER DIRECT DEPOSITION PROCESS OF Ti-6Al-4V ALLOY S.Y. Gao1,H.Z. Ji1,Y.Z. Zhang2,B.L. Du1,M.Z. Xi2,L.K. Shi2 (1.Mechanical Engineering College, Yanshan University, Qinhuangdao 066004, China;2.Beijing General Research Institute for Nonferrous Metals, Beijing 100088, China) Abstract:Laser direct deposition (LDD) of metallic components is an advanced technology of combining CAD/CAM......
of direct laser metal powder deposition. Both analytical and numerical models were developed to calculate the transient temperature profiles, dimension of the fusion zone, etc., of thin-wall parts. XI et al[13] numerically simulated the transient temperature field in the real process of the metal thin-wall part fabricated by laser direct deposition. Soon afterwards, XI and YU[14] established......
