	1	Texture Evolution and Ultrafine Grain Formation in Cross-Cryo-Rolled Zircaloy-2显示文摘The texture and mechanical properties of cross-rolled zircaloy-2 at 77 and 300 K were investigated.Crossrolling at 77 K was performed to impart different thickness reductions of 25% and 50%,while at 300 K with 25%,50%,75% and 85% reductions to the sample.EBSD analysis of deformed sample showed that near-basal orientation is not deformed completely after 50% rolling reduction.The activation of prismatic silp,f11 '22g contraction twin and f10' 12 g extension twin were evident from the deformed microstructure at 77 K.The propensity for activation of basal slip \a[ at77 K was also observed.The deformation of the sample at 300 K occurs by prismatic,basal \a[ and pyramidal \c a[slips,which were predicted by pole figures.After annealing,the tensile strengths(735 and 710 MPa) are almost the same for 50% cryo-cross-rolled and room-temperature cross-rolled zircaloy-2 with almost 2.7% difference in their ductility.KAM analysis of the deformed samples was made to estimate the stored strain energy and dislocation density.Annealing of deformed sample at 673 K for 30 min results in recrystallization,which leads to the formation of ultrafine grains.
