Twelve-pass friction stir processing (FSP), with 50 pct overlap was carried out on aluminum alloy 5086-O rolled plates to obtain total area of 40 x 150 mm2. Two methods of friction-stir processing, intermittent multipass friction stir processing (IMP), and continuous multipass stir processing (CMP) were carried out, and their effect on the mechanical properties of the processed material was studied. The results revealed that material subjected to IMP showed better mechanical properties compared with the material subjected to CMP. Also, a variation in mechanical properties was observed with an increase in the tool traverse speed for single-pass, CMP, and IMP types of processing.
