High-strength Ti sheets could be fabricated by effective grain-refinement through high-ratio differential speed rolling for a thickness reduction of 63% in a single rolling pass at room temperature. Formation of narrowly spaced shear bands distributed uniformly over the entire thickness section of the sheet and a high temperature rise by intensive shear banding during rolling resulted in the formation of ultrafine grains with the size of 0.1-0.3 mu m. The rolled Ti sheet exhibited an ultimate tensile strength of 895-915 MPa. (C) 2009 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
