Wear behavior and its correlation with mechanical properties of TiB 2 reinforced aluminium-based composites

Abstract

Aluminium-based TiB 2 reinforced composite is a promising material to be used as brake drum material, and it may emerge as substitute for conventional gray cast iron. Aluminium-based composites containing 2% by wt copper reinforced with 2.5 and 5wt% TiB 2 composites were made in induction furnace by in situ synthesis process using simultaneous addition of halide fluxes (K 2TiF 6 and KBF 4). These cast composites were evaluated for microstructures, hardness, flow curve properties, and tensile properties. It was observed that overall wear behavior gave reasonably good correlation with mechanical properties of composites as compared to gray cast iron. Copyright © 2011 N.B.Dhokey and K.K.Rane.
