Effect of Magnesium on Hardness and Microstructure of Metal Matrix Composite Al.6061/(Al₂O₃)_p Produced by Stir Casting Route

Abstract:

Al.6061/Al₂O₃ metal matrix composites (MMCs) has been fabricated by stir casting. The MMCs were prepared by addition of Al₂O₃ particulates reinfoced with varios Mg content, 8, 10, 15 %wt Mg. Al.6061/Al₂O₃ composites with different Mg contents were successfully fabricated by stirring technique under optimum processing conditions. Effects of Mg content on microstructure and hardness were studied by Scanning Electron Microscopy (SEM)-EDX, SEM-Xray Map, XRD and Rockwell Hardness. The results indicate that Al₂O₃particles disperse homogeneously in Al matrix and interfacial reaction between Al matrix and Al₂O₃ particles is effectively controlled. Distribution of Al₂O₃ reinforcement and interfacial bonding were improved by adding Mg. Additionally, the hardness of composites were remarkably improved with the Mg. The highest hardness of composites obtained in 15%wt Mg with a value of 55 HRB.
