增材制造(AM)技术以其可设计性强、近净成型等优点,在非连续增强钛基复合材料(DRTMCs)等金属基复合材料领域引起了广泛关注.AM技术通过快速凝固的成型方式,能有效拓宽对DRTMCs微观组织和力学性能的调控窗口.金属AM技术主要分为粉床熔融法(PBF)和定向能量沉积法(DED).粉床熔融法包括选区激光融化(SLM)技术和电子束熔融(EBM)技术,定向能量沉积法主要包括激光熔化沉积(LMD)技术和电弧增材制造(WAAM)技术.本文综述了近年来利用以上技术制备硼化钛(TiBw)增强DRTMCs的研究现状.从粉末状态出发,讨论了混合粉末和预合金化复合粉末对DRTMCs中TiBw的尺度特征参数、基体组织以及力学性能的影响规律.在此基础上,对目前存在的关键问题和未来的发展趋势进行了展望.
Research progress in additive manufacturing of titanium boride reinforced titanium matrix composites
Additive Manufacturing(AM)has attracted widespread attention in the research and application fields of non-continuous reinforced titanium-based composite materials(DRTMCs)and other metal-based composite materials,due to its advantages of high design flexibility and near-net shaping of complex components.AM technology can effectively expand the control window on the microstructure and mechanical properties of DRTMCs through rapid solidification molding.Metal AM can be divided into powder bed fusion and directed energy deposition.PBF mainly include selective laser melting(SLM)and electron beam powder bed fusion(EBM),while DED mainly include laser metal deposition(LMD)and wire arc additive manufacturing(WAAM).This article reviews the recent developments in preparing titanium boride(TiBw)reinforced DRTMCs by using the above technologies.Starting from the powder state,the influence of mixed powder and pre-alloyed composite powder on the scale characteristic parameters,matrix structure,and mechanical properties of TiBw in DRTMCs was discussed.Based on this,the key issues and future development trends are also discussed.
