Development of β → ω and β → α phase transformations in the rolled quenched alloy Zr-20%Nb was studied by methods of X-ray texture diffractometry. Usage of a position sensitive detector allowed to construct, besides usual texture pole figures, distributions of X-ray line broadening and lattice elastic deformation depending on the orientation of reflecting planes. Diagrams of correlation between pole figures of different types for β-, ω- and α-phases were analyzed to reveal factors controlling inhomogeneity of phase transformations and substructure features of derivative phases.
