Regularities of Changes in Structure and Texture of Low Modulus Alloy Zr-25Nb at Cold Rolling of Monocrystals with Different Orientations
Abstract
The paper presents the results of studying the regularities of formation of the rolling texture in single crystals of Zr-25%Nb alloy, with different initial orientation relative to the external principal directions in the sheet: normal (ND) and rolling direction (RD). Varying the initial orientation of the single crystal made it possible to reveal stable orientations, among which are textural components {001} <100>, {001} <110>, {111} <110> and {111} <112>. For orientation <111> of single crystal, in the matrix of a quasi-single crystal it was possible to detect a finely dispersed ω-phase, which causes the appearance of an extended halo in the diffraction spectrum. The presence of
