英文摘要	The friction stir brazing (FSB) were conducted to achieve the connection of TC4 and Al6082 by adding various thickness of brazing filler Zn. Then, the tensile and shear tests of the welded Ti/Al joint were carried out, and comparison was made on the shear strength of Ti/Al joint with various thickness of brazing filler Zn. Scanning electron microscope (SEM) and energy dispersive spectrometer (EDS) were employed to observe and analyze the cross-section microstructure of the joints. The differences of the cross section microstructure and fracture modes of the Ti/Al joint with various thicknesses of brazing filler Zn were distinguished. Furthermore, the temperature distribution of the Ti/Al joint under the optimum FSB parameters was obtained. It could be found from the research results that the Ti/Al joint with 0.05 mm thick brazing filler Zn exhibit the highest sharing strength (154 MPa), about 75% of that of the base metal. The intermetallic compound AlZn formed in the central region of the interfacial layer, and there was scarcely any Ti-Al intermetallic compound. The fracture mode of Ti/Al joint was defined as mixed fracture of brittle and ductile fracture. Regarding to the temperature distribution on the Ti/Al joint, the peak temperature first rose and then dropped as the location gradually away from the weld center, and the forward side held higher temperature than the backward side. The formation order of the intermetallic compound at the Ti-Zn-Al interface was TiAl2, TiAl3, TiAl and AlZn under the highest temperature of 260. © 2019, Materials Review Magazine.
