Evaluation of Mechanical Properties of Aluminum Alloy (Al2024) Reinforced with Silicon Carbide (SiC) Metal Matrix Composites

Abstract

The investigation of mechanical properties of silicon carbide (SiC) powders reinforced with aluminum alloy composites are recorded in this paper. SiC powders of approximately 35µm size were added in an aluminum alloy matrix to manufacture the samples of ratios 1, 2, 3 and 4 by weight % using the stir casting technique. The specimens were fabricated and several tests were conducted to evaluate the mechanical properties such as tensile strength, hardness and impact strength and then the values are compared with the base alloy. It has been observed from the results that the hardness, impact energy and tensile strength increases with the increase in % of SiC particles until 2% and drops on further increase in the SiC particles.
