Grain-Structure Development in Heavily Cold-Rolled Alpha-Titanium (Postprint)

Abstract

High-resolution electron back-scatter diffraction (EBSD) analysis was employed to establish mircostructure evolution in heavily cold-rolled alpha-titanium. After thickness reductions of 75% to 96%, significant microstructure and texture changes were documented. The surface area of high-angle grain boundaries was almost tripled, thus giving rise to an ultra-fine microstructure with a mean grain size of 0.6 m. Moreover, orientation spread around typical split-basal rolling texture substantially increased. These effects were suggested to be related to the enhancement of pyramidal (c+a) slip.
