Development, Testing and Characterization of Al NanoTiC_p Composites through Powder Metallurgy Techniques

Abstract

In the present scenario, weight diminution and strength enrichment are the main requirements for escalating the application of a nano composite material in different sectors. Several industrial sectors, such as automobile, defense and aerospace, are making various components of nano composites with the help of powder metallurgy processing. In this study, Al nanoTiCp composites (2, 4 and 6 wt %) were contrived through modified powder metallurgy (PM) techniques with the help of Cold Isostatic Compaction process (CIP). The mechanical properties such as density, porosity, micro-hardness, compressive strength and indirect tensile strength were increasing with the reinforcement of nanoTiCp particles up to 4 wt % in Al metal matrix composites. Nevertheless, clustering of nanoTiCp particles were found at 6 wt %, which is also observed in SEM images.
