Abstract

Composite joints with high-performance close to the parent materials of aluminum matrix composites were fabricated by a new joining technology assisted by ultrasonic vibration. We found both the microstructure and the mechanical performance were systematically dependent on the volume fraction and the distribution of reinforcement particles in the bond region. This study can be generalized to the bonding of other ceramic-reinforced metal matrix composites.
