Channel angles of 90° and 110° and common corner angle 30° have been considered for this study. It has been revealed that the channel angle has a significant influence on deformation homogeneity, microhardness, ultimate tensile strength, ductility and corrosion behavior of Mg alloys. Investigation with reference to as-received AZ80 Mg alloy indicates 18.47% improvement in UTS and 76.07% enhancement in ductility after processing through 3P-90° and 2P-110° ECAP, respectively. Also, the corrosion rate reduces to 89.47% after processing the sample with 3P-110° ECAP die. © 2019, ASM International.CorrosionCorrosion rateCorrosive effectsDuctilityGrain size and shapeMagnesium alloysMechanical propertiesPressing (forming)ProcessingTensile strengthAZ80Channel angleCorner angleECAPGrain sizeEqual channel angular pressing
