In some friction stir technologies (FST), the friction stir processing (FSP) is expected to be a microstructure refinement method for crystalline materials. In this study, we have applied the friction stir processing method to a 7075-T6 and -O aluminum alloys as a grain refinement method. Microstructure refinement with the average grain size of about 4μm was achieved for the 7075-T6 and -O aluminum alloys. This result suggests that the friction stir processing is a useful method as microstructure refinement for the 7075-aluminum alloys. In this paper, the mechanical properties of the friction stir-processed materials at room and high temperatures are briefly discussed. The mechanical properties of the unprocessed materials are also compared with those of the processed materials.
