Different heat treatment systems were used to heat treat new type of architectural aluminum matrix composites reinforced with graphene. The mechanical properties and wear resistance of the composites were tested and analyzed. The results show that the tensile strength, yield strength and elongation at break of the mechanical vibration assisted heat treatment increase by 6%, 9% and 11%, respectively, and the wear volume decreases by 22% compared with the conventional heat treatment. The 40Hz ultrasonic vibration assisted heat treatment The tensile strength, yield strength and elongation at break of the materials increased by 23%, 34%, 91% and 53% respectively. The tensile strength, yield strength and elongation at break of 20Hz ultrasonic vibration assisted heat treatment Respectively. The tensile strength, yield strength and elongation at break of the 60Hz ultrasonic vibration assisted heat treatment increased by 18%, 26%, 54%, respectively, and the wear loss increased by 9%, 14%, 32% Reduced by 39%. The heat treatment system is preferably 40 Hz ultrasonic vibration assisted heat treatment.
