Investigation on mechanical properties wear behaviour and machinability studies of titanium diboride and boron carbide reinforced lm13 aluminium alloy hybrid composites

Abstract

Composite materials have been generally utilized in automobile, newlineaerospace, transport, communication and marine applications because of its newlinehigh strength, better wear resistance, high stiffness and stability at elevated newlinetemperatures. Researchers have been focusing to develop a novel composite newlinethat offers high strength to weight ratio, high stiffness to weight ratio with newlinedesirable wear resistance. newlineComposite material is a combination of two or more dissimilar newlinematerials having a prominent interface between them such that the properties newlineof the resulting material are superior to the individual material. The major newlineconstituent is matrix and reinforcements have been added to improve the newlinemechanical properties and wear behavior of composites. Composites have newlinebeen manufactured by many production methods viz., powder metallurgy, newlinediffusion bonding, spray co-deposition, in-situ solidification and casting newlineprocess. Among all methods, casting process is most economical, simple and newlinefeasible method to produce metal matrix composites. In this casting process, newlinecomposite melt is poured into a preheated die to produce components with newlinerequired shape and size. The various casting processes are used to fabricate newlinethe metal matrix composites. Stir casting is one of the most economical and newlinesimplest methods to manufacture the hybrid composites. This method offers newlinebetter bonding to the particles and uniform dispersion of reinforcement in the newlinematrix. newline
