Abstract
The effect on microstructure of overlapping multiple pass friction stir processing (FSP) of an AlSi9Mg cast aluminum alloy was investigated. The microstructure was examined by means of scanning and transmission electron microscopy. The studies show that the multiple pass FSP resulted in the elimination of porosity, the refinement of second phase particles and the decrease of grain size within the processed material surface. Electron back scattering diffraction analysis showed that high angle grain boundaries prevailed in the processed material. However, relatively high dislocation density revealed by transmission electron microscopy indicated that the recrystallization was not completed. The investigation showed that the FSP technique may be successfully used for producing a homogeneous near-surface layer in a cast aluminum alloy.
