Abstract
A process for the fabrication of zirconium alloy sheet specifically intended for the manufacture of structural elements for boiling water reactors, which includes the following steps: a) producing in a vacuum an ingot having the composition of the desired alloy; b) forging and hot rolling the ingot; c) quenching of the blank thus obtained after reheating in the beta range; d) hot rolling after heating; e) heat treatment in the alpha range; f) at least one cycle of cold rolling followed by a heat treating in the alpha range; and g) final cold rolling followed by subcritical annealing in the alpha range; where the hot rolling of the sheet after quenching from the beta range is carried out in an initial direction, then in a direction perpendicular to the initial direction.
