- Abstract
In this research work, electrical conductivity of a novel cast 6351 Al-AlSiC composite has been studied for varying AlSiC particle content (2-7 vol%). Analytical models were developed on the basis of free electron theory and local resistance approach in order to predict electrical conductivity of metal matrix composites. The electrical conductivity of cast 6351 Al-AlSiC composite was found to decrease with increasing AlSiC content. Overprediction of results and more % deviation of the predicted electrical conductivity from experimental value were observed for local-resistance-approach-based model. However, the model developed on the basis of electron theory considering scattering of electrons at particle-matrix interface accurately predicted the experimental electrical conductivity data.
