Abstract
The viability of utilizing cheaply sourced quarry tailings (QTs) particles as reinforcing materials for the development of
low cost high performance aluminium matrix composites for structural and industrial applications was explored.
Aluminium alloy (A6063) was reinforced with 2 – 10 wt. % of 80 µm QTs particulates using stir casting method.
Microstructural, mechanical and wear characterisations were carried out on the composites. Micro hardness and ultimate
tensile strength of the composites were improved with addition of reinforced particulate in the base matrix alloy. Addition
of quarry tailings reinforcements also decreased the wear rate of the composites from 245 mm/Nm3 to 180 mm/Nm3 for 10
N and from 260 mm/Nm3 to 135 mm/Nm3 for 15 N. Optical and SEM examinations revealed uniform distributions of the
QT particles in the molten matrix
