| Abstract: | Laser direct deposition of metallic components is a combining technology of CAD/CAM, high power laser, and rapid prototyping. The mechanical properties of Ti 6Al 4V alloy fabricated by laser direct deposition were studied, the effect of low temperature anneal and hot isopressing on the mechanical properties were analyzed, the oxygen content of as deposited test pieces was measured, and the appearance of tensile fracture surface was observed. The results indicate that the mechanical properties of as deposited test pieces are higher than that of casting ones, and equivalent to that of wrought anneal ones. |
