Characterization of functionally Gradient sic b4c rubber ash Reinforced with aluminium alloy 6061 Matrix

Abstract

newlineImprovements in the performance parameters are essential for automobiles and aircrafts, as light-weight materials that meet the functional parameters have become essential. For any product to meet its functionality effectively it needs to have enhanced physical and mechanical properties; most automotive components require enhanced properties with optimal weight to strength ratios. These parameters are met by functionally graded metal matrix composites (FGMMCs). These composites have a few disadvantages despite their enhanced properties, such as poor tensile strength and ductility, reduced fracture toughness and related properties, ill-defined manufacturing process and standard dimensional constraints. newlineThere is an increasing need for lightweight materials in the automobile sector owing to their specific strength. This demand for FGMs is the drive for various researches on functionally graded materials (FGMs) and their manufacturing techniques. This work focuses mainly on the manufacturing process and material selection for reinforcements of aluminum-based FGMs. newlineThe FGMs are required to have a variation in their properties in different zones. This variation in the material property can be achieved by centrifugal casting. This casting technique provides enhanced physical and mechanical properties to the FGM without increasing the production costs much. Aluminium 6061 (Al6061)/metal matrix and the reinforcements are varied in volume concentrations to achieve the optimal composition that produces enhanced tensile and hardness while the wear is reduced. The SiC and B4C particles are used as reinforcements along with aluminum alloy.
