, the hardness descends rapidly when the peak aging is past after 3 h. Therefore, the best heat treatment processes of Al2O3p/Al-Cu-2.0Mg composite and the matrix alloy are keeping at 160 ℃ for 8.5 h... composite with those of Al2O3p/Al-Cu-2.5Mg composite. It can be seen that the hardness of alloy and composite after heat treatment (aging) can be improved by increasing Mg content of matrix alloy. 4......
