TA15钛合金因其优良的高温强度、良好的热稳定性和抗腐蚀性能，被广泛应用于军工航空航天领域，特别是飞机隔筐、壁板和航天器舱段等工作温度较高、受力较复杂的重要结构件。与传统加工工艺相比，增材制造的累积成形方式可以更好地满足TA15钛合金“结构功能一体化”的制造要求，避免了多零件组装焊接带来的成本损失和工作隐患。在众多增材制造工艺中，激光选区熔化工艺由于成形精度高、组织性能可控性强，成为TA15钛合金结构件制备研究中应用最广泛、基础最成熟的工艺。系统综述了激光选区熔化工艺制备TA15钛合金的研究进展，基于SLM工艺原理从显微组织与缺陷、SLM工艺参数、热处理、数值模拟4个方面，分析激光选区熔化成形TA15钛合金的组织演变及性能变化规律。最后结合现有研究的不足，对未来TA15钛合金增材制造技术的发展方向进行展望。
Abstract：TA15 titanium alloy is widely used in military and aerospace fields due to its excellent high-temperature strength, good thermal stability and corrosion resistance, especially for important structural components with high service temperatures and complex stress conditions, such as aircraft bulkheads, wall panels and spacecraft cabin sections. Compared with traditional processing technologies, the cumulative forming mode of additive manufacturing can better meet the manufacturing requirements of “structural and functional integration” for TA15 titanium alloy, and avoid the cost loss and potential risks caused by the assembly and welding of multiple parts. Among many additive manufacturing technologies, selective laser melting(SLM) has become the most widely used and mature technology in the research and fabrication of TA15 titanium alloy structural components due to its high forming precision and strong controllability of microstructure and properties. The research progress of SLM-fabricated TA15 titanium alloy is systematically reviewed. Based on the SLM process principle, the evolution laws of microstructure and properties of SLM-fabricated TA15 titanium alloy were analyzed from four aspects: microstructure and defects, SLM process parameters, heat treatment and numerical simulation. Finally, combined with the shortcomings of existing studies, the future development trends of additive manufacturing technology for TA15 titanium alloy were prospected.
