Investigations On Hardness And Tensile Behavior Of Micron Sized Titanium Carbide Particles Reinforced Al2014 Alloy Composites

Abstract

The current research focuses on investigating the microstructural and mechanical properties of Al2014 reinforced with both titanium carbide particles. The composite material was produced using a novel casting method. In this study, TiCcontent was varied at levels of 3 and 6 wt. %. Employing scanning electron microscopy (SEM) tool, microstructural analyses were conducted, revealing a uniform dispersion of ceramic TiC particles within the Al2014 composites. Mechanical testing, following the ASTM standards, was carried out on the composites, specifically assessing hardness, tensile strength, yield strength, and percentage elongation to evaluate the properties of the Al-based MMCs. The findings of this study indicate a significant enhancement in both tensile and yield strength values for the fabricated composites. However, it is important to note that the percentage elongation decreases as the reinforcement content in the composite increases.
