ABSTRACT:
For manufacturing zirconium alloy plates, more particularly for forming grids for holding nuclear fuel elements, a strip is obtained by hot rolling, then cold rolling, with a high cold hammering rate, then the strip is subjected to reheating for removing the tension at a temperature lower than the recrystallization temperature. Plates are cut out in the transverse direction of the strip.
