Effect of stir casting parameters and mono/hybrid reinforcements on aluminium metal matrix composite–A review

Aluminum metal matrix composites are a new class of materials that have gathered more attention from many materialists. Especially, the automotive components like a piston, cylinder block, brake drum, etc., fabricated by different reinforcement, which has exposed better performance over conventional engineering materials. Aluminum composites are generally fabricated by stir casting technique due to simplicity in operation and adaptive to mass or job order production. The paper provides a background for the readers interested in the production of metal matrix composites through stir casting. Based on the literature assessment, the special attentions taken by the researchers to enhance the uniform distribution of particle to avoid agglomeration are discussed. The composite performances mainly depend on the aluminum matrix, particle size, the quantity of reinforcement, preheating temperature of reinforcement, and processing parameters such as stirring speed, stirring time, and wetting agents. The selection of two reinforcements and their suitable parameters for wetting are attaining interest by many researchers and maybe opted as future scope.
