Abstract

In this study, Equal Channel Angular Pressing (ECAP) of Al-Mg-Zn/SiCp composites was experimentally investigated. Using powder metallurgy (PM), different sets of Al-Mg-Zn/SiCp composites with different concentrations of Mg and SiC were prepared by hot pressing, which are then subjected to ECAP process in a furnace at 373K up to 1 or 2 passes using route C. Post experimental evaluation of mechanical properties showed that material hardness was increased following each ECAP pass. However, no substantial change was observed in wear resistance of the composites. Despite the lack of significant effect on the wear resistance, some small variations in hardness and wear resistance among different sets of samples are observed, which are weakly related to Mg and SiC content in the composites.
