摘要：

Processes of rolling after extruding and rolling after hot-pressing of multi-layer spray deposited Al-8.5Fe-1.3V-1.7Si/SiCp, and the effect of the two different processes on the microstructure and mechanical properties of the composite were investigated. The microstructure of the composite prepared by different processes was observed by OM, SEM and TEM. The results showed that more uniform microstructure and more excellent mechanical properties of the composites were obtained by rolling after hot-pressing than rolling after extruding. The excellent mechanical properties can be attributed to avoiding of SiC particles lamination which is familiar to the composite as-extruded by hot-pressing, stable microstructure, and good bonding between SiC particles and the matrix.
