Abstract

High temperature deformation behavior and texture evolution during ECAP(equal channel angular pressing) of Zn-0.3Al alloy were investigated in this study. ECAP was conducted at temperatures from $40^{\circ}C$ to $160^{\circ}C$ on the plate type specimen of 5mm thickness and 20mm width. The specimens obtained by ECAP showed typical texture with basal poles tilted away from the ND toward ED. A series of compression tests was carried out at temperatures from RT to $200^{\circ}C$ under the strain rate from 0.03 to 10/s. With the strain rate increased, serration behavior was observed to be prominent.
