<p>Aluminium metal matrix composites, have emerged as a potentially useful high class of materials in recent years. The surface roughness and wear characteristics of the material are the fundamental material factors that must be taken into consideration during the design and optimization of composite structures and behaviours. Boron carbide (B₄C) is used as a reinforcement in aluminium matrix composites in order to boost the material’s conductivity. These composites are also distinguished by their mechanical qualities, such as their hardness and tensile strength. Stir casting was used to manufacture LM25 aluminium alloy metal matrix composites that were reinforced with Boron Carbide (B₄C) particles in concentrations of up to 3, 6, and 9%. The composites that were made in this way were analysed to determine their mechanical qualities, such as their hardness and tensile strength, as well as the degree to which the micro reinforcing particles were dispersed throughout the material. The findings suggest that stir casting might be a more cost-effective method for manufacturing hybrid composites than other approaches. In contrast to micro particles reinforced composites, hybrid particle reinforced MMCs display superior levels of both strength and hardness. Observations made with a scanning electron microscope (SEM) of the microstructures revealed that the dispersion of micron-sized particles was more uniform, whereas the presence of hybrid particles led to the agglomeration of the particles.</p>
