The secondary recrystallization of drawn pure Mo wires has been studied. Particular attention has been paid to the effect of temperature gradients in the annealing process. The secondary recrystallized grains were obtained by annealing at about 2000/sup 0/C. Orientations of the wire axis of the secondary recrystallized grains are mainly <023> or <135>, while oriented grains are less frequently observed. In contrast, the primary recrystallized texture consists of the <011> main component and <023>-<012> sub-component; many <011> oriented grains have large grain sizes. The discrepancy in orientation between the primary and secondary recrystallized grains is explained in terms of the difference in grain boundary mobilities which depend on the character of grain boundaries.
