Evaluating the microstructure evolution and wear behavior of friction stir processed aluminum matrix surface composites with nano-sized SiC particles

Abstract

In this research, Al6061 matrix composites were prepared via friction stir processing (FSP) to investigate the effect of incorporation of nano-SiC particles on dynamic recrystallization (DRX) and wear behavior. The microstructure was evaluated using electron backscattered diffraction (EBSD) and transmission electron microscopy (TEM), respectively. Wear and microhardness testing were performed on the various samples to investigate the differentiation. The results illustrated that the percentage of subgrain boun…
