The increasing demand for efficient materials in the automotive industry gave a great scope for development of metal matrix composites. In the present study, Al-4Cu-0.5Mg-2SiC composite is prepared through powder metallurgy route. The powder mixture is compacted and pressure less sintered at 550oC for 1 hour in control atmosphere (Argon gas). The relative density of the sintered preforms is found to be 90% approximately. Sintered preforms are used as workpiece materials for deformation study at different temperatures in order to find the effect of temperature on the densification behavior. The stress strain curve is obtained during the deformation process. The effect of deformation on the hardness of the composite is studied.
