Formation of Inhomogeneous Texture and Structure in Metal Materials under Equal-Channel Angular Pressing
Texture analysis and the new X-ray method of Generalized Pole Figures (GPF) were used by the study of texture and substructure inhomogeneity of Ti rods, submitted to Equal-Channel Angular Pressing (ECAP) at 400oC. Local texture features testify about gradual rotation of loading axes by ~15o when crossing the rod’s section. As a result of second pass (route C), the specific ECAP texture weakens and the textureless component intensifies. Observed substructure changes are connected with development of dynamic recovery and dynamic recrystallization.
