Effect of grain size on compression behavior of magnesium processed by Equal Channel Angular Pressing

Year: 2013

Type: article

Abstract: Commercially pure magnesium was processed by a single pass of Equal Channel Angular Pressing (ECAP) at 523 K.The grain structure was evaluated at the region near the intersection between the channels of the die. Compression test workpieces were machined from the as-received material and the material processed by ECAP. These workpieces were tested at room temperature. The results show the grain structure is refined in the intersection between the channels. The ECAP processed material displays higher strength and reduced surface bulging due to the refined structure. The plastic flow during compression of the ECAP processing material concentrates along bands of refined grains.
