The objective of this work was to investigate the effect of cold forging on mechanical properties and microstructural study of Al MMCs, at different wt% of SiC and forging cycle. The Al-SiC composite material was fabricated by stir casting method at different weight percentage of SiC such as 4% and 6%. Further, the deformation characteristics during open-die forging of Al-SiC composite at cold conditions were investigated. Cast and forged composite material was subjected to hardness test, tensile test and impact test. The grain size, microstructure behavior was investigated using optical microscope and SEM. The FEA method was used to evaluate various characteristic properties such as effective stress, strain, velocity, damage, total load in DEFORM-3D. Results showed that due to forging cycle the grain size was reduced by 30% to 35% from initial size. In FEA analysis results show that maximum effective stress, velocity, damage and decrease in strain is presented were high at 60% of forging cycle and 6 % SiC.
