Evaluation of Mechanical Properties and Micro Structural study of AA 7050 Reinforced with SiC Metal Matrix Composite

Abstract

The present work deals with the fabrication of the Aluminium matrix composites by ultrasonic dispersion of silicon carbide particles in molten Aluminium Alloy. AA7050 has been selected as matrix alloy as it is readily castable. The mechanical properties such as hardness, Young’s modulus, tensile strength will be studied and compared with those of the base alloy. The correlation of the properties with respect to the variation of the processing parameters, viz., and weight percentage will be done. The weight percentage of silicon carbide will be varied from 0 to 20%. The proposed values are for chosen based on the literature data. In addition, the analysis of the micro-structural properties of metallurgical structure and grain size will be carried out.
