Effect of Hardness, Tensile and Wear Behavior of Al-4.5wt%Cu Alloy/Flyash/SiC Metal Matrix Composites
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 1
Abstract
Abstract: Metal-matrix composites (MMCs) have emerged as potential alternatives to conventional alloys in high-strength and stiffness applications. In the present investigation Al-4.5wt.%Cu alloy reinforced flyash and SiC particulates were casted by liquid metal stirring casting technique. The 2wt.%flyash with 2, 4, 6wt.%SiC and 4wt.%flyash with 2, 4, 6wt.%SiC were reinforced in Al-4.5wt.%Cu matrix. The composites were tested for hardness, tensile strength and dry sliding wear behavior. The results show improved hardness, tensile strength and wear resistance with increase in percentage of reinforcements. Optical micrograph indicates better bonding between matrix, flyash and SiC particle with no fracture initiation at matrix particle interface.
