摘要：
The SiC/Al-Mg-Cu-Si-Sn composites with different quantities of SiC particles by volume were fabricated using hot-pressing sintering. The effects of SiC volume fraction on the microstructure, Vickers hardness, and corrosion behavior of the composites were studied using the optical microscope, scanning electron microscope, Vickers hardness test, and corrosion testing. The results show that adding SiC particles shortened the time required to reach the peak-aged state of the composites and increased the hardness. Corrosion potentials of the composites did not vary greatly or show any definite trends in relation to the amounts of the SiC contents.
