<p>A large range of engineering applications can be suited to hybrid metal matrix composites because of their improved mechanical properties, making them superior to conventional materials. Hybrid composites are widely used in the automotive and aerospace industries because they feature excellent wear resistance, corrosion resistance, high strength, and low density. This paper demonstrates how to use the stir casting method to create a hybrid composite. The current focus of research is on the fabrication of composites using triple particle silicon carbide (5% weight) and graphite (1.5% weight) as the reinforcements and A357 as the matrix. Wear analysis of the composite materials was conducted following the Taguchi L18 method. To obtain insight into how control factors and heat treatment parameters affect the wear rate of composites, the prescribed number of experiments was carried out. Using ANOVA, major influencing factor for the wear rate accomplished was the sliding distance of all the developed hybrid composites.</p>

<p>The present study aims to develop stir cast A357 composite reinforced with triple particle size silicon carbide and graphite. Using Taguchi’s L9 orthogonal array, the influence of heat treatment parameters on mechanical characteristics of A357 reinforced with triple-size silicon carbide and graphite particles was investigated. Tensile strength and hardness were the core mechanical properties investigated for the composites. Taguchi’s observational design was used to determine the effect of solutionising temperature, soaking time, ageing temperature, and ageing time on tensile strength and hardness. The homogeneous dispersion of silicon carbide particles in A357 matrix can be observed using an optical microscope. The results showed solutionising temperature has the most favourable effect for both tensile strength and hardness followed by ageing time, soaking time, and ageing temperature.</p>
