摘要

This study examines impact of particle size and weight percentage on mechanical characteristics of Al-Si alloy-based composites that have brass slag reinforcement. Stir casting route was employed to incorporate fine particle size between (100–215 µm) and coarse particle size between (215–350 µm) brass slag particles into the Al-Si matrix at 3, 6, and 9 wt.%. The composite reinforced with 9 wt.% fine brass slag (FBS) exhibited the most significant enhancement in mechanical performance. Optical micrographs showed that brass slag particles were evenly dispersed through the matrix. It is also noticed that the 9 wt.% fine particle reinforced composite samples exhibits increased ultimate tensile strength (UTS), yield strength, and toughness, with enhancement of 49.5%, 44.2%, and 57% respectively, in comparison to base alloy. In order to determine impact strength, Charpy and Izod impact tests were utilized. An Improvement of 75% in impact strength with FBS particle as compared to base alloy under simply supported loading condition whereas improvement of 35% is shown under cantilever loading condition.
