摘要

Laser melting deposition (LMD) process was used to fabricate Ti-6Al-2Zr-Mo-V alloy directly. The metal powders were continuously melted and rapidly solidified layer upon layer directly into the near-net shape structure. The elements were fully melted and uniformly mixed in the molten pool that homogenized dense microstructure was obtained. Laser deposited Ti-6-Al-2Zr-Mo-V is characterized by a fine α/β lamellar microstructure with various random orientations, which should be related to the rapid solidification and phase transformation during the process. The influence of deposition layer on the fatigue strength is discussed.
