Abstract
Among the various Severe Plastic Deformation (SPD) processes, Equal Channel Angular Pressing (ECAP) is one of the most applicable one
which improves strength and ductility due to grain refinement and suitable texture development. In this study, cold rolling were carried out on the
4 pass ECAPed (in route A and C) strip shaped specimens of AZ31 magnesium alloy to investigate the ECAP effects on the roll-ability. Results
showed that reduction in area which can be concerned as an index for roll-ability inc
