| 摘要: |
| 选区激光熔化(SLM)3D打印技术作为近年来快速兴起的增材制造技术，在航空航天、国防和生物医疗用高性能钛合金及其复合材料关键及复杂结构件方面具有显著优势、发展潜力巨大.SLM 3D钛合金晶粒细小且常含有大量的α′马氏体，而SLM 3D钛基复合材料中则通常可以原位生成纳米尺度的TiBw和TiCp等陶瓷增强相，使得成形构件的力学性能显著优于铸件和粉末冶金制品水平.本文在介绍SLM 3D打印技术的原理与特点基础上，着重评述了其在钛合金及其复合材料的应用基础研究及工程应用进展，并对未来相关关键基础科学与技术问题进行了展望. |

| Abstract: |
| As a kind of rising additive manufacturing technology in recent years, selective laser melting (SLM) 3D printing technology has significant advantages and broad prospects in key and complex structural components of high-performance titanium alloys and titanium matrix composites for aerospace, national defense, and biomedical applications. The microstructure of titanium alloys produced by SLM mainly consists of fine acicular α′martensites while in situ nanoscale TiBw and TiCp ceramic reinforcement phase can be formed in the SLM process of titanium matrix composites. As a result, the components produced by SLM 3D printing technology show better mechanical properties than those of casting and powder metallurgy. Based on the introduction of the principles and features of SLM 3D printing technology, this paper mainly reviews the basic research and engineering application progress on SLM 3D printing of titanium alloys and titanium matrix composites, and looks into prospects of the related key basic science and technology problems. |
