Abstract

PREPARED BY THE CONVENTIONAL POWDER METALLURGY (P/M) ROUTE WERE THE 6061 ALUMINUM ALLOY AND ITS PARTICULATE COMPOSITES CONTAINING UP TO 14 VOL.% OF GRAPHITE, TALC, ALUMINA, AND TIC DISPERSOIDS; PROPERTIES LIKE YIELD STRESS, HARDNESS, POROSITY, ULTIMATE TENSILE STRENGTH, AND ELONGATION WERE EVALUATED; USING SCANNING ELECTRON MICROSCOPY, FRACTOGRAPHS WERE OBSERVED; THE COMPOSITES CONTAINING TIC SHOWED IMPROVEMENT IN PROPERTIES OVER THAT OF THE BASE ALLOY, WHEREAS THOSE CONTAINING GRAPHITE SHOWED MINIMUM MECHANICAL PROPERTIES AMONGST ALL TYPES OF COMPOSITES; THE MECHANICAL BEHAVIOR OF THE COMPOSITES IS EXPLAINED ON THE BASIS OF INTRINSIC PROPERTIES OF DISPERSOIDS AND SINTERING CHARACTERISTICS OF THE COMPOSITE.
