Formation of Texture and Structure in Rods of Copper and Titanium under Equal-Channel Angular Pressing

摘要

New data on structure and texture features of Cu and Ti rods, subjected to ECAP at 20℃ and 400℃ respectively, were obtained by means of advanced X-ray diffractometric methods. A deformation inhomogeneity through rod's cross-section was studied by reduced cubic samples 3x3x3 mm, cut out from different regions of rods. The inhomogeneity of ECAP rods is characterized by distributions of texture and substructure parameters. Main tendencies in structure formation by ECAP are revealed.
