Mechanical characterisation and experimental analysis of AA6082 Aluminium metal matrix composites reinforced with goat bone ash

Abstract

ABSTRACT Aluminium matrix composites signify a recent advancement in the progression of metal matrix composites, possessing the capability to meet the requisites of various emerging engineering applications. This study aims to concentrate on the mechanical behaviour of AA6082, which was fortified with goat bone ash (GBA). Employing the stir casting technique for casting, aluminium-based metal matrix composites were synthesized, incorporating varied weight percentages (0%, 3%, 6%, and 9%) of goat bone ash as the strengthening element. The introduction of 3% ash particles yielded a 12% augmentation in impact strength, while an even more significant enhancement of 81% in hardness was attributed to the incorporation of 9% ash particles. The material exhibited a tensile strength of 131 MPa without reinforcement, and this value was significantly enhanced by 36.6% upon adding 6% GBA. Subsequently, it was inferred that reinforcement significantly enhanced the physical and mechanical attributes of aluminium metal matrix composites.
