Abstract:

Aluminum-based metal matrix composites are continuously changing to meet the industry’s specialized needs. In the aluminum alloy series, the AA5052 had a lightweight, high strength, good weldability, excellent corrosion resistance, and a good surface finish during the machining operation. The present work is to improve the mechanical characterization of AA5052 by adding 1 and 2 wt % of Aluminium Titanate (Al2TiO5) reinforcement particles through a stir casting process. The influences of Al2TiO5 reinforcement particle’s microstructural analysis were investigated. The tensile, impact and hardness of the AA5052/ Al2TiO5 composites were also determined by Universal Testing Machine (UTM), Charpy, and Vickers microhardness tester, respectively. The AA5052/ 2%- Al2TiO5 composite microstructure shows a uniform grain distribution. The increased wt 2 % of reinforced particles to AA5052 resulted in an improved microhardness (73.4 HV) and tensile strength (210.28 Mpa). The AA5052/ Al2TiO5 composites can be utilized for various structural applications due to their superior mechanical properties.
