Abstract
In this work, the effect of heat treatment on the mechanical properties and the microstructure of heat treated aluminium alloy LM 25 (Al-Si7-Mg) as well as on the metal matrix composite (LM 25), reinforced with tungsten carbide (WC) has been experimentally studied. The composites were fabricated through Stir Casting Method with LM 25 as matrix material and tungsten carbide (WC) with 0%, 3%, 6% and 9% by weight as reinforcement material. The specimens were made as per ASTM standards in order to test for its tensile strength, hardness and wear performance. It is observed that LM 25 alloy aged at 150 °C has better mechanical properties. Significant improvement in tensile strength and hardness is observed with addition of WC as reinforcement. The results show up to 30% improvement in wear strength of 6% and 9% wt WC when compared to 0%wt WC. The property enhancement of the composites can be achieved by adding WC in to LM 25.
