A popular processing method, ECAP (equal channel angular pressing), was employed to process commercial pure magnesium. A magnesium sample experienced eight ECAP cycles, and then was sliced and prepared to observe the microstructure of two cross-section planes. The overall microstructure was obtained for both planes to reveal the global microscopic features of ECAPed magnesium. The results indicate that there are extensive deformation twins; different regions of each plane have different amounts of twins; overall, the center region tends to have fewer twins compared with the peripheral region for each cross-section plane; and the area of the region with low twin density decreases when the cross-section plane moves close to the middle of the sample along the pressing direction.
