Abstract

This study aimed to explore the impact of varying weight percentages of tungsten carbide (WC) reinforcement dispersed in an Al2024 solid solution. The homogenization of WC particulates (β-phase) within the Al2024 solid solution (α-phase) was achieved using the stir casting technique. Following casting, the specimens underwent a three-stage heat treatment process, including solutionizing, water quenching, and artificial ageing, with durations of 1, 3, 5, and 7 hours. Microstructure analysis and ultimate tensile strength investigations were carried out on both the as-cast and heat-treated specimens, following ASTM standards. The results highlighted that incorporating 8% WC by weight into the Al2024 solid solution with a 7-hour ageing duration significantly influenced the mechanical properties. Particularly, the presence of a lamellar eutectic microstructure (WC) played a vital role in altering the mechanical properties of the Al2024 alloy. The study focused on a comprehensive analysis of the composite material's microstructure and phase composition to gain insights into the interaction between WC particles and the Al2024 matrix during the heat treatment process.
