Abstract
A method of making a strip of ZIRCALOY 2 or 4 is disclosed wherein an ingot is worked, roughly shaped into a billet then quenched from the beta range, hot rolled in alpha range, annealed and cold rolled to 0.3 to 0.9 mm. The O and C, in ppm, are selected to satisfy the formula: O.sub.2 <1200-0.75 x C (R) so that a T texture is obtained systematically for thicknesses of at least 0.8 mm. The disclosure also concerns the strips obtained. The method can be applied to obtaining strips of excellent formability for the production of components for nuclear water reactors.
