Review on Mechanical & Wear Behavior of Aluminum-Fly Ash Metal Matrix Composite.

Abstract--In recent years, metal matrix composites (MMC) reinforced with fly ash particulates have attracted considerable interest due to their inherent good mechanical properties such as tensile strength, compression strength, hardness, wear resistance etc. Further, incorporation of fly ash provides overall weight reduction & filler material, thereby substitution of Al alloy. In this paper an attempt has been made to provide an extensive literature review on the overall performance of these fly ash reinforced composites fabricated by stir casting. Literatures in each category are reviewed according to the key factors mentioned. The literature review framework in this paper provides a clear overview of the usage of fly ash as a reinforcing agent in different Al alloy matrices along with its distinctive performances. Keywords-- Aluminum alloy, fly ash, MMC, stir casting, Tensile strength, wear etc. I
