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.
