摘要
激光选区熔化技术是在精密复杂零部件制备方面应用较广的激光增材制造技术之一,可实现复杂零件的近净成形。从成形工艺参数和固溶时效处理两方面,对现阶段激光选区熔化成形TC4合金显微组织及力学性能控制的研究进展进行了综述,并对其后续发展方向进行了展望。
Selective laser melting technique is a widely used laser additive manufacturing technology in preparation of precise and complex parts,which could realize the near net forming of complex parts.Through the forming process parameters,and solution and aging treatment methods,the research progress of microstructure and mechanical properties control of TC4 alloy formed by selective laser melting in the current stage is reviewed,and the future development direction is prospected.
