Abstract: \gamma-\mathrmTiAl Al alloy is a promising light weight and high-temperature structural material in the aerospace industry. It is of great significance for promoting its engineering application to realize the high-quality brazed joint of \gamma-\mathrmTiAl Al alloys. In this paper,the research progress at home and abroad was reviewed from the aspects of the wettability of filler metals,the type of filler metals（ Ti-based,Ag-based,Al-based） and the influence of process parameters on the microstructure of joints. The main problems were pointed out,including the lack of applicable high temperature filler metals for \gamma-\mathrmTiAl Al alloy,the control mechanism of interface reaction and the evaluation standard for the comprehensive properties of joints. In the future,there are five main research directions in the field of brazing of \gamma-\mathrmTiAl Al alloy:（1） composition design of high tem-perature brazing filler metal;（2） prediction methods of joint microstructures and properties;（3） further investigations of metallurgical behavior of joint interface;（4） control mechanism of interfacial microstructures;（5） test and evaluation criteria of comprehensive properties of the joints.
