Deformation behaviour of commercial pure aluminium during multiple pass equal channel angular pressing (ECAP) through route #C has been evaluated using finite element analysis. The results obtained indicate that a parallelogram shaped uniform plastic strain distribution can be obtained in the work piece. The plastic strain variation along the top, middle and bottom of the work piece along its length suggests that during multiple pass ECAP following route #C, a uniform plastic strain can be obtained in the work piece after every two passes if one can neglect the front and back end of the work piece. The length of these ends that need to be removed in ECAP processed work piece was found to be equal to the ECAP channel width (w). Further, it has been established that during multi-pass ECAP through route #C, the corner gap subtended by the work piece is independent of its geometry, whereas the load-displacement curve is dependent on the work piece geometry.
