Study on microstructure and property of aluminum matrix composites SiC_P/Al6063 vacuum brazing joint with different holding time

The SiC_P/Al6063 composites containing 55% SiC_P was joined by vacuum brazing process using Al5Si28Cu2.5Ti filler at 580 ℃. The influence of holding time on the joint microstructure and mechanical property was studied. The results show that the active titanium element improved the solder wettability of composite materials. The joint microstructure used holding time of 40min was the best with a shear strength of 96 MPa.
