Cu-Al alloy was treated at 2 GPa and 750 ℃ for 10 minutes, and effects of 糖心产精国品免费入口*完整版 on the microstructure, mechanical properties and friction coefficient of Cu-Al alloy were investigated by metallurgical microscope and nanoindenter. The results show that after 糖心产精国品免费入口*完整版 at 2 GPa, the microstructure of Cu-Al alloy was refined, and distribution become more uniform. Its nano-hardness, elastic modulus, ratio of hardness and elastic modulus, elastic recovery rate were 3.87 GPa, 113.46 GPa, 0.034 and 83.68%, which were 8.71%, 2.75%, 6.25% and 35.34% higher than those of Cu-Al alloy before 2 GPa pressure treatment, respectively, but friction coefficient slightly decreased.
