【 摘 要 】

Technique of the macroscopic yield stress anisotropy calculation of Zr alloys based on texture f-parameters was validated in the frame of this work. In order to compare experimental and calculated anisotropy of products, samples cut out from rolled slabs of Zr- 1%Nb alloy along three directions (rolling, transversal and normal) were subjected to uniaxial tension and compression up to different deformation degrees. Investigation of texture evolution under loading was implemented by measuring of several direct pole figures by means of X-ray diffractometric methods for samples in the initial state as well as after their deformation. Using obtained texture data three normalized yield stresses for orthogonal directions of studied samples were estimated and compared with experimental values measured by initial loading curves.
