Application of metal matrix composite fabricated by reinforcement materials – A review

Abstract

Metal Matrix Composites (MMCs) are recently developed fabricated materials with characteristics like reduced thermal expansion coefficient, enhanced specific strength, improved wear resistance, and light in weight. They contain feature such as low density, good strength-to-weight ratio, lightweight, low cost, excellent quality, and high performance. Among others, Aluminium (Al) and Al alloy based MMCs are employed in a variety of industrial applications. The characteristics of the composite are greatly influenced by the Al-based MMC fabrication processes. The manufacturing processes for reinforced composites as well as contemporary fabrication techniques are reviewed in present article. The impact of various process factors on the characteristics of aluminium based MMC has also been discussed. Various techniques such as powder metallurgy, stir casting, hand lapping etc. are utilized for the fabrication of composites. The primary objective of the present work is to review different fabrication methods of Al MMCs along with their features. This article also deals with changes occur in mechanical and physical properties with fabrication methods. The effects of the addition of different reinforcement have also been discussed in the present work. Investigation of mechanical and microstructure properties have also done in this paper. The main purpose of this review is to find effect of fabrications process on different properties of fabricated material as well as finding of suitable method of fabrication.
