K465合金激光增材制造加工工艺研究
Research on Processing Technology of Superalloy K465 via Laser Additive Manufacturing
摘要
Abstract
The manufacturing of superalloy K465 component with special cavity via laser additive manufacturing was studied,in order to meet the design requirement of aerospace component with special cavity and ensure the mechanical properties at high temperature.The results indicated that the crack occurred during the additive manufacturing of superalloy K465 structure,because of the poor deformability and the existence of eutectic phase with low melting point,which made it to difficultly manufacture alone via laser additive manufacturing.By addingthe Stellite 6 alloy reasonably and reliefing the stress and heating the substance,the crack in the laser additive manufacturing significantly decreased.关键词
