An experimental investigation of texture evolution during high temperature compression of Mg-3Sn-2Ca (TX32) alloy containing 0.4%Al using electron back scatter diffraction (EBSD) technique is reported. Isothermal uniaxial compression tests were performed in the temperature and strain rate ranges 300-500°C and 0.0003-10 s-1 to examine the influence of processing conditions on the dynamic recrystallization (DRX) behavior and texture evolution. The onset of DRX during compression at low temperatures (300 and 350°C) and low strain rates (0.0003 and 0.001 s-1) gave rise to a fine, partially recrystallized and necklaced grain microstructure, with the basal poles located at 15-30° from the compressive direction although they were split. Specimens deformed at temperatures higher than 450°C resulted in a fully recrystallized microstructure and an almost random crystallographic texture. It is clear from Schmid factor analysis that the contribution of pyramidal slip system is significant for deformation at temperatures above 450°C.
