Abstract

Procédé pour éliminer en totalité ou en partie les fractions séparées d'alliages et d'impuretés, y compris les fractions riches en étain, dans les alliages de zirconium. On chauffe l'alliage à une température d'au moins 1 000 degrés C environ pendant une durée suffisante pour éliminer les fractions séparées par homogénéisation dans l'alliage, en respectant les conditions déterminées par l'équation:A process for removing all or part of the separate fractions of alloys and impurities, including tin-rich fractions, in zirconium alloys. The alloy is heated to a temperature of at least about 1000 degrees C for a time sufficient to remove the fractions separated by homogenization in the alloy, under the conditions determined by the equation:
