Features of Texture and Structure Development in Zirconium under Equal-Channel Angular Pressing

초록

A detailed X-ray study of Zr rods, subjected of ECAP at 350 degree by routes C and Bc, was conducted by the new X-ray method of Generalized Pole Figures, combining texture measurement with registration of X-ray line profiles. The data analysis is based on conceptions of the texture formation theory, connecting features of grain reorientation with activated deformation mechanisms. A degree of reproduction of the same distinctive texture by successive ECAP passes with antecedent rotation of the rod reflects attendant structure changes in material.
