Effect of fly ash content in Aluminum matrix composite through stir casting method on mechanical and physical properties

Abstract

Metal Matrix Composite (MMC) is a potential innovation material to meet the requirements required in various applications. such as in the aerospace, automotive and mining sectors. Stir casting has been known widely as a methode to produce MMC. In this study, Alumunium alloy and fly ash is utilized as matrix composite and reinforced phasing, respectively. Effect for mechanical and physical properties are investigated for the addition fly ash (4, 8 and 12wt%). Alumunium alloy melt with fly ash is stirred with 350 rpm for 5 minutes and poured into the mold at temperature of 800°C. Hardness, impact and density test are performed to investigate the characterization of specimen. The experimental results show that maximum value is obtained at 8 wt% fly ash with 65.83 HB, 11. 8 Joule, 14.299 Kgf/mm2 and 2.7 g/cm3 for hardness, impack, tensile strenght and density, respectively.
