Abstract: Aluminium matrix composites are considered as a multi-property material system and this can be tailorable to suit the specific applications. In-situ synthesis is one of the methods to fabricate the composite with high inter-facial strength, increased wettability and cluster-free reinforcements. AA6061-TiB₂/ZrB₂ in-situ metal matrix composites are synthesised by K₂TiF₆-KBF₄-K₂ZrF₆ reaction. Presence of the reinforcing phases is confirmed by energy dispersive X-ray analysis and scanning electron microscopic analysis. The objective of this paper is to study the influence of in-situ formed TiB₂ and ZrB₂ on mechanical properties and wear rate per percentage of the reinforcement. Experimental result shows that the inclusion of the reinforcement particles increases the mechanical properties and we note the significant improvement on wear rate per percentage of the reinforcement. Fracture surface investigation is carried out to identify the mode of failure of the composites due to the tensile load.
