摘　　要：新型金属间化合物基层状复合材料Ti/Al3Ti具有高强度、高模量、高刚度、低密度以及高的断裂韧性等优异性能,在航空航天、武器装备及地面军用车辆的装甲防护系统等方面有着广阔的应用前景。迄今为止,针对金属间化合物基层状复合材料Ti/Al3Ti的制备,人们发展了冷轧、热轧、脉冲电流热压、真空烧结、无真空烧结和爆炸焊接等制备技术。概述了国内外对新型轻质高性能金属间化合物基层状复合材料Ti/Al3Ti的研究现状,着重阐述了金属间化合物基层状复合材料Ti/Al3Ti制备技术的工艺原理及其特点,为Ti/Al3Ti的发展和应用提供基础。最后从不同研究方向展望了金属间化合物基层状复合材料Ti/Al3Ti未来的主要研究趋势。The novel metal-intermetallic laminate （MIL） composite Ti/Al3 Ti has excellent performances, such as high strength, high modulus, high stiffness, low density and high fracture toughness, and it has a broad potential application in aerospace, weapons and protective system of ground military vehicles. For fabricating Ti/Al3 Ti metal-intermetallic lami- nate composite, various synthesis techniques were developed until today, mainly including hot rolling, pulse current hot pressing, sintering in vacuum and air conditions, and explosive welding technique, each of which has its advantages and limitations. The present work reviewed the current research progress of a novel Ti/Al3Ti metal-intermetallic laminate com- posite in domestic and abroad, with the emphasis focused on the development history, and processing methods of various synthesis techniques of the Ti/Al3Ti metal-intermetallic laminate composites, and could provide the foundation and assistance for the development and application of Ti/Al3Ti laminate composites. In the end, this review predicted research trends of the Ti/Al3Ti metal-intermetallic laminate composite from different research directions.
