摘　　要：在航空航天和汽车工业领域,轻质高强耐高温的TiAl合金板材是重要的战略结构材料。然而,TiAl合金板材成形难度大,尤其是大尺寸高性能TiAl合金轧板的制备更是困难。本文从TiAl合金轧板制备方法研究现状出发,综述了近年来铸锭冶金轧制、粉末冶金轧制、铸锭直接热轧和叠轧法制备TiAl合金板材的工艺、尺寸、组织和力学性能,论述了上述制备方法的特点及存在的不足,提出了关于制备大尺寸高性能TiAl合金轧板的建议以及未来发展方向。TiAl alloy sheets are important strategic structural materials in aerospace and automotive industry because of their high strength-to-weight ratio and high service temperature.However,the preparation of TiAl alloy sheets is difficult,especially the rolling of large-size high-performance TiAl alloy sheets.The preparation process,size,microstructure,and mechanical properties of hot-rolling TiAl alloy sheets using ingot metallurgy,powder metallurgy,direct rolling,and roll bonding approaches in recent years were reviewed.The features and existing problems of the above processing routes were discussed.Meanwhile,some suggestions on rolling large-size TiAl alloy sheets and its future development were proposed.
