Abstract

Aluminium reinforced with TiB₂ is an emerging class of metal matrix composites for many engineering applications such as automobiles, aerospace and naval vessels. The initial part of the present work study involves melting of individual fluxes of KBF₄ and KTiF6 in premelted aluminium in an induction furnace. In the later part of the work covers the combined effect of these fluxes to produce aluminium metal matrix composites containing 2.5% TiB₂. The effect of the varying amount of KBF₄ on kinetics of TiB₂ formation and elimination other unstable phases was studied. The material was examined for hardness, microstructures and wear rates using Pin-on-Disc test machine, XRD and SEM-EDX analysis. The effect of TiB₂ on properties was analysed. It was concluded that an optimum level of KBF₄ is needed to get critical population of TiB₂ particles in the matrix.
