Uniaxial tension and advanced expansion due to expression tests were applied to prepare different deformed Zr-2.5Nb cladding samples. The total tensile strains have reached to a maximum value of 20% in tube axial and hoop direction, respectively. The microstructure and texture evolution during each deformation process will be comparatively investigated by EBSD technique.
