PRODUCTION OF CONTAINERLESS MOLD OF METALLIC COMPONENT AND COMPRISING SINGLE CRYSTAL |
摘要 |
A containerless method of producing a crack free metallic article of near-net shape includes melting a filler material into a metallic substrate or seed under conditions chosen to preclude cracking. In a preferred embodiment of the invention, a laser beam is operated at a relatively low power density and at a relatively large beam diameter at the substrate surface for an extended length of time to produce a molten pool with a low aspect ratio. Near-net shape is achieved by applying the process in a closed-loop, multi-axis material deposition system. <IMAGE> |
