A Review on Properties of Aluminium Based Metal Matrix Composites via Stir Casting
Aluminium metal matrix composites are significantly important in the various demanding fields of medicine and engineering like aerospace, defense, automobiles, dental and consumer goods. The industrial need of good materials with light weight, excellent properties and low cost demanded the scientists to research on composite materials. Among the MMCs, aluminium matrix composites (AMMCs) sought over other conventional materials because of their high strength to weight ratio, high wear resistance and low economic. These AMMCs offer a large variety of mechanical properties depending on the chemical composition of the Al matrix. The reinforcement in AMMCs could be in the form of continuous/discontinuous fibers, whisker and particulate as second phase depending on their applications and property requirements. Addition of various reinforcements such as fly ash, TiC, SiC, Al2O3, TiO2, B4C etc. to aluminum matrix will enhance the mechanical and tribological properties. This paper attempts to review the different combinations of the usage of reinforced materials as a reinforcing agent in different Aluminium matrix alloys in the processing of aluminium metal matrix composites along with its properties.
