Effect of Weight Percentage on Mechanical Properties of Boron Carbide Particulate Reinforced Aluminium Matrix Composites

Abstract:

Aluminium matrix composites (AMCs) play a vital role as advanced engineering materials due to their excellent mechanical properties like light weight, strength, wear resistance, toughness. This work focuses on the fabrication of aluminium (AA6061) matrix composites reinforced with 3%, 6% and 9% B₄C particle of 104μm using stir casting method. The wettability of B₄C particles in the matrix has been improved by adding K₂TiF₆ flux in to the molten metal. The microstructure and mechanical properties of the fabricated AMCs are analyzed. Uniform distribution of B₄C particle in the matrix was confirmed using scanning electron microscope (SEM) images. It was found that the tensile strength and hardness of the fabricated AMCs increases with increased B₄C particle content.
