Abstract
Metal matrix composites based on an aluminium alloys were produced by powder metallurgy route, involved unidirectionally hot pressing under 500 MPa for 15 minutes at temperature about 0.95 Ts [Solidus Temperatu re]. Metal matrix contains different weight percents of SIC, alpha rAl (2)O(3), WC and Si3N4 with different particle size. Wear and mechanica l tests have been carried out on composites, and it was found that abo ut 90% of wear reduction occured in composite with 30% SIC compared wi th pressed matrix.
