摘要
随着航空航天、汽车工业等领域的快速发展,Ti基复合材料(TMCs)因其高强度、低密度、高温耐久性和优异的耐磨性而受到广泛的关注,通过增材制造技术制备的Ti基复合材料有着广泛的应用前景。在Ti基材料中添加合适的强化相可改变复合材料的微观结构和性能。介绍了几种常用的增材制造方法及其特点,包括选区激光熔化(SLM)、激光金属沉积技术(LMD)、电子束熔化技术(EBM)和激光近净成形技术(LENS),综述了通过原位反应生成和直接添加强化相对Ti基复合材料的影响,为进一步研究增材制造增强钛合金及复合材料性能提供了理论依据。
With the rapid development of aerospace and automotive industries,Ti-matrix composites(TMCs)have received extensive attention from advanced engineering materials due to their high strength,low density,high temperature durability,and excellent abrasion resistance.Ti-matrix composites prepared by additive manufacturing technology have a wider range of application prospects.By adding suitable reinforcing phases to Ti-matrix materials,the microstructure and properties of composites can be changed.The study introduces several commonly used additive manufacturing methods and their characteristics,including selective laser melting(SLM),laser metal deposition(LMD),electron beam melting(EBM)and laser near-net-shaping(LENS);and summarizes the effects of generating and directly adding reinforcing phases to Ti-matrix composites through in situ reaction,so as to provide a theoretical basis for further research on the properties of Ti-matrix composites reinforced by additive manufacturing.
