Abstract

Gr/2024Al composite material and TC4 titanium alloy were successfully brazed with self-developed Ag-Cu-Sn-Ti filler alloy, and the interfacial microstructure and mechanical properties of the brazed joints were investigated. The results show that the typical interfacial structure of brazed joint was Gr/2024Al composite material/Ti₃AlC₂/Ag₂Al+Ag₃Sn+Al₂Cu+Al₅CuTi₂/Al₅CuTi₂/TC₄ titanium alloy. With the increasing of brazing temperature and extending of dwelling time, the amount of Al2Cu compounds decreased but the amount of Al₅CuTi₂ increased and it finally grew into bulk in the brazed seam. While brazed at 953 K for 10 min, the joint obtained maximum shear strength of 17 MPa at room temperature.
