Abstract:

The present study describes the processing and characterization of hypoeutectic A319 functionally graded Aluminium metal matrix composite (FGMMC) reinforced with 10 weight percentage SiCp particles of 23 μm size. FGMMC’s are processed by liquid stir casting method followed by vertical centrifugal casting. Metallographic analysis of FGMMC casting reveals the influence of the centrifugal force on the gradation of various phases in the matrix and an increasing gradient distribution of SiC reinforcements gradually from inner towards the outer periphery forming different zones. Tensile and the compressive tests show that the variation in properties are structure sensitive and is confirmed by the dry wear tests. The study clearly depicts the gradient nature in the structure and mechanical properties of the FGM castings produced by centrifugal casting method.
