摘要
激光选区熔化(SLM)作为一种直接制造金属构件的增材制造技术,可实现复杂结构件的高精度制造。介绍了SLM技术的发展现状及原理,从材料体系、成形工艺、显微组织及力学性能方面论述了国内外钛及钛合金SLM技术的研究及应用现状,总结了SLM技术加工钛及钛合金过程中存在的问题,及对其未来的发展趋势进行了展望。
As an additive manufacturing technology to fabricate metallic components directly, the selective laser melting （SLM） can be used to fabricate complex structures with a high precision. The development status and principle of SLM technology are introduced, and the research and application status of SLM technology of titanium and titanium alloys at home and abroad are discussed from several aspects, which include material systems, forming processes, microstructures and mechanical properties. Furthermore, the problems and future trend of SLM technology for titanium and titanium alloys are summarized and prospected, respectively.
