Microstructure and Properties of Aluminum Matrix Compositite Joint with Transient Liquid-phase Diffusion Bonding Process
The aluminum matrix compositite was welded by transient liquid-phase bonding process using Ag-Cu-In-Sn filler in argon atmosphere. The microstructure and mechanical properties of the transient liquid-phase bonding joint was analyzed by changing bonding temperature.The results show that as the welding temperature increasing,the weld seam is narrowed, and the shear strength increases. The microstructure and properties of TLP bonding joint are best with the bonded temperature at 580 ℃ heated for 6 min. The shear strength of the welded joint is 80 MPa.
