Abstract

The evolution of texture in Zr-2.5 Nb during uniaxial compression was studied in annealed specimens with α grain sizes of 5 and 10 μm. It is shown that texture development is determined by the mechanism controlling <c>-axis deformation. In fine grained material <c+a> and <a> slip are found to be responsible for texture evolution. Tensile twinning controls the formation of a sharp [0001] compression texture in coarse grained material. It is suggested that the mode of <c>-axis deformation is determined by the α grain size.
