Abstract

This study deals with the feasibility of using boron carbide (B4C) as reinforcement for aluminum matrix composites (AMCs) obtained by solid-state processes (powder metallurgy and extrusion). Two different reinforcements were considered: B4C as the object of this study and SiC for direct comparison of results. Aluminum alloy AA6061 was used as matrix in all cases. Comparative analysis between both SiC and B4C composites was focused on mechanical and tribological properties and correlated to microstructural features. Hardness and strength increased for composites together with volume fraction of reinforcement, reaching its maximum value to 10% B4C. Regarding tribology, composites showed an increased dynamic friction coefficient but a lower wear rate than the unreinforced aluminum alloy. Applications as brake disks for automotive industry are foreseen.
