Role Of Fabrication Route On The Mechanical And Tribological Behavior Of Aluminum Metal Matrix Composites - A Review

Aluminum matrix composites (AMCs) are the new emerging materials of this generation which can be tailored and engineered to obtain specific required properties for special applications. AMCs are recognizably different category of advanced engineering materials having superior properties over other conventional aluminum alloys. AMCs exhibits attractive properties of high hardness, better yield strength, strength to weight ratio, high thermal conductivity, low coefficient of thermal expansion, superior wear and corrosion resistance. Due to this they have repealing keen interest in recent times for various potential applications in aerospace, automotive and various other structural applications. Use of AMCs is constantly growing over the years, because of its better physical, mechanical and tribological properties as compared to other metal matrix composites. Extensive research and development has been made in the Al-based MMCs with every possible alloy and different reinforcements by using different synthesis techniques so as to get the material of desired properties. By suitable use of metal matrix and the reinforcement a wide range of properties combination can be obtained. This paper attempts to review the role of different types of fabrication routes in the AMCs. In this paper we also briefly discuss the major fabrication-synthesis techniques, properties characterization, applications and the future scope of AMCs. (C) 2018 Elsevier Ltd. All rights reserved.
