Comparison of the effects of b4C and SiC Reinforcement in Al-Si Matrix Alloys Produced via PM Method

Abstract

Reinforcement kind and ratios have significant effects on the metal matrix composite (MMC) materials. In this study, two different (B4C and SiC) reinforcement compounds between 5 and 15 wt% reinforcement ratios were used in Al-Si main matrix composite materials. Samples were produced via powder metallurgy (PM) method and were subjected to metallographic investigation with; SEM, EDS, FASTMAP, Optical Microscope analyzing methods. Microvickers measurements were carried out as HV1 load. The effects of B4C and SiC reinforcement in MMC were compared in details with these investigations. © 2019, The Minerals, Metals & Materials Society.
