High energy ball milling is employed to fabricate 100–150 nm sized WC which is reinforced with aluminium metal through liquid metallurgy process. Stir casting technique is used to produce the Al–WC composite in which the homogeneous distribution of WC reinforcement particles in Al matrix is obtained. WC is reinforced in the proportion of 2, 4, 6, 8, and 10% by weight with the aluminium metal matrix to prepare the composites. The results show the steady improvement of the composites properties when compared to the aluminium metal. Thus Al–WC nanocomposites guarantee for high strength, wear resistance, hardness, and exceptional microstructure stability at high temperatures.
