Fabrication of Al-TiC Composites by Three-Step Powder Metallurgy: Microstructure and Mechanical Properties
Main Article Content
Abstract
Owing to improving the mechanical properties, titanium carbide (TiC) strengthened Al-TiC composites were fabricated by three-step powder metallurgy (PM). A dense microstructure was obtained because of the small size TiC, which fills the inter-particle space. The porosity of Al-TiC composites was decreased from 5.16 to 1.52% due to the inclusion of TiC powder. The mechanical properties of Al-TiC composites improved because of effective necking of matrix (i.e., Al and TiC) particles. The Al-TiC30 composite exhibits enhanced mechanical properties (i.e., yield strength: 176.28 MPa, compressive strength: 301.57 MPa and hardness: 38.8 HRC) than the mechanical properties of unalloyed Al. The enhanced physical and mechanical properties of Al-TiC composites made them promising for automobile and aerospace applications.
