[Abstract]:The graphene reinforced new building aluminum matrix composites were heat-treated with different heat treatment systems, and the mechanical properties and wear resistance of the materials were tested and analyzed. The results showed that compared with the conventional heat treatment, the mechanical properties and wear resistance of the composites were tested and analyzed. The tensile strength, yield strength and elongation after break of mechanical vibration assisted heat treatment materials are increased by 6% and 9%, respectively, and the wear volume is reduced by 22 ~ 40 Hz ultrasonic vibration assisted heat treatment materials. The yield strength and the elongation after breaking are increased by 23%, respectively, and the wear volume is reduced by 53 Hz and 20 Hz ultrasonic vibration assisted heat treatment material's tensile strength. The yield strength and the elongation after breaking are increased by 9%, respectively, and the wear volume is reduced by 32 Hz and 60 Hz ultrasonic vibration assisted heat treatment material's tensile strength. The yield strength and the elongation after breaking are increased by 18%, respectively, and the wear volume is reduced by 39%. The optimum heat treatment system is 40Hz ultrasonic vibration assisted heat treatment.
