Abstract

L'INVENTION CONCERNE UN PROCEDE DE TRAITEMENT DE SOUDURES, AMELIORANT LES PROPRIETES MECANIQUES. ELLE SE RAPPORTE A UN PROCEDE QUI COMPREND LE CHAUFFAGE DE SOUDURES A UNE TEMPERATURE COMPRISE ENTRE 1200 ET 1480K, AVEC SIMULTANEMENT APPLICATION D'UNE PRESSION ISOSTATIQUE COMPRISE ENTRE 34,5 ET 344,7MPA. LA PRESSION ET LA TEMPERATURE SONT MAINTENUES PENDANT UN TEMPS QUI SUFFIT A LA REDUCTION DE LA POROSITE ET A L'AUGMENTATION DE L'HOMOGENEITE DE L'ALLIAGE. CELUI-CI A UNE MEILLEURE DUCTILITE ET UNE MEILLEURE RESISTANCE AU CHOC, ET LA DISPERSION DES PROPRIETES EST REDUITE. APPLICATION AU TRAITEMENT DES SOUDURES POUR REACTEURS NUCLEAIRES.
