Notes:
The recrystallization of a Zr-2Hf alloy sheet deformed by plane strain compression atroom temperature and then heat treated in the temperature range 500-650°C is studied. The microstructure, local and global crystallographic textures are investigated by EBSD and X-ray techniques. The as-deformed condition exhibits a heterogeneous microstructure composed of highly and less deformed zones, the EBSD indexing of the latter ones being more reliable. The asdeformed condition displays a (0001) 〈 0 1 10 〉 crystallographic texture. The evolution of themicrostructure during recrystallization very much depends on the amount of local deformation. Recrystallization begins in highly deformed zones, new grains having two variants of texture components, {0001} 〈 0 1 10 〉 and {0001} 〈 0 2 11 〉. Some change of preferred orientations concomitant with grain growth at 600 and 650°C has been observed with a decrease in the {0001} 〈 0 1 10 〉 component and an increase in the {0001} 〈 0 2 11 〉 component
