摘要：
Differential speed rolling (DSR) was carried out on commercial pure titanium at rolling temperatures from room temperature to 773 K The basal texture appears when the rolling temperature is higher than 573 K and it lacks stability during annealing. Originating from texture effects, the DSRed sheet exhibits a larger Lankford value and a smaller planar anisotropy, which lead to a remarkable improvement in stretch formability regardless of a decrease in tensile elongation compared with symmetrically rolled sheet (C) 2010 Acta Materialia Inc Published by Elsevier Ltd All rights reserved
