摘要：
An as-cast austenitic stainless steel was hot deformed at 1173 K, 1223 K, and 1373 K (900 degrees C, 950 degrees C, and 1100 degrees C) to a strain of 1 with a strain rate of 0.5 or 5 s(-1). The recrystallised fraction is observed to be dependent on dynamic recrystallisation (DRX). DRX grains nucleated at the initial stages of recrystallization have similar orientation to that of the deformed grains. With increasing deformation, Cube texture dominates, mainly due to multiple twinning and grain rotation during deformation.
