Abstract

The effect of friction stir processing on the electrical resistivity of aluminium alloy (AA6082) is characterised and reported in this paper. The AA 6082 aluminium alloy was friction stir processed at three rotational speeds of 1500, 2500 and 3500 rpm and three different traverse speeds of 50, 150 and 250 mm/min. The processed samples were characterised by optical microscopy and electrical resistivity measurements. Optical microscopy showed a decrease in the grain size of the processed metal compared to the base metal. The electrical resistivity measurements showed that the resistivity of the processed samples is higher compared to the base material.
