Enhancement of Mechanical properties of AlSi5Cu3 Aluminum alloy using TiB 2 reinforcements

Abstract

In present investigation, ex situ composite of AlSi5Cu3 aluminum alloy reinforced through TiB 2 reinforcement particles has been developed. Different weight percentage of TiB 2 particles were incorporated in liquid melt via stir casting method. Combine effect of stirrer speed (500,700 rpm), and weight percentage (1, 2, 3) TiB 2 particle on mechanical properties were studied. Microstructural study has been carried out using optical microscopy and SEM analysis, which shows homogeneous distribution of particles and improvement in grain size compare to aluminum alloy AlSi5Cu3. Presence of TiB 2 was confirmed using XRD analysis. Improvement in tensile strength and hardness was observed due to homogeneous distribution of particles.
