摘要：

Commercially pure (CP) Ti was subjected to a complex severe plastic deformation (SPD) processing route consisting of equal channel angular pressing swaging and drawing, resulting in the formation of a homogeneous ultra fine-grained (UFG) microstruc ture showing a very high strength The significant anisotropy of mechanical properties found in the processed rod is related to a very strong crystallographic texture developed during SPD processing The features of plastic deformation of the UFG CP Ti are dis cussed with respect to its crystallographic texture (C) 2010 Acta Materialia Inc Published by Elsevier Ltd All rights reserved
