Reactive processing and mechanical properties of Al/SiCP composite

The reactive process for Al/SiCP composite was studied. SiC particles were in-situ coated by the exothermal reaction of SiC-Ti powder compact in Al melt bath, and easily incorporated into Al melt. The detailed study was carried out to understand the microstructures of the reacted SiC particles. During the reaction and consequent mixing, the successive processes include in-situ coating on the reacted SiC particles, coat dissolution and SiCP splitting. The tensile mechanical properties of 6013Al/SiCP composite processed by the present technology showed that the reacted SiCP considerably reinforced the 6013 matrix.
