Abstract EN
In this study, Cu-SiCp/AZ91D composites were prepared with high-density pulse currents.
The wettability between SiCp and matrix during solidification was improved by coating 0.095-μm thick copper film on the surface of SiCp.
By comparing the composites prepared with/without pulse currents, the solidification structure and its formation mechanism of Cu-SiCp/AZ91D composites were analyzed under different conditions.
The Cu-SiCp/AZ91D composites prepared without high-density pulse currents were mainly composed of α-Mg, β-Mg17Al12, and a small amount of Mg2Si phases, with coarse grains and uneven structures.
Under the action of high-density pulse currents, the structures of Cu-SiCp/AZ91D composites were transformed into α-Mg and Mg2Si phases with refined grain, and the homogeneity of the structures was improved significantly.
