| description | The zirconium-based material proposed according to the present invention contains the following components (proportions are given in wt %): niobium 0.5 to 1.5; tin 0.9 to 1.5; iron 0.3 to 0.6; chromium 0.005 to 0.2; carbon 0.005 to 0.04; oxygen 0.05 to 0.15; silicon 0.005 to 0.15; zirconium accounting for the remainder. The proposed article made from the said material for use in the active zones of atomic reactors has a microstructure formed by the zirconium matrix reinforced by particles of tin- and iron-containing intermetallic compounds, at least 60 % by volume of the total quantity of the iron-containing intermetallic compounds consisting of intermetallic particles of the type Zr(Nb,Fe)2, Zr(Fe,Cr,Nb), and (ZrNb)3Fe. The distance between particles is 0.20 to 0.40 mu m. The process for producing the above mentioned articles involves producing an ingot, preliminary beta-treatment thereof, production of a blank by hot forming the ingot at the temperature at which alpha-zirconium exists, annealing the blank at a temperature of 380 to 650 DEG C, cold forming the blank with intermittent annealing at the temperature at which alpha-zirconium exists, and final working of the blank to make the finished product.
Matériau à base de zirconium qui contient les constituants suivants (les proportions sont indiquées en pourcentage en poids): niobium 0,5 à 1,5, étain 0,9 à 1,5, fer 0,3 à 0,6, chrome 0,005 à 0,2, carbone 0,005 à 0,04, oxygène 0,05 à 0,15, silicium 0,005 à 0,15, le reste étant constitué par du zirconium. L'article de la présente invention constitué dudit matériau et destiné à être utilisé dans les zones actives de réacteurs atomiques possède une microstructure formée par la matrice de zirconium renforcée par des particules de composés intermétalliques contenant de l'étain et du fer, au moins 60 pour cent en volume de la quantité totale de composés intermétalliques contenant du fer étant constitués de particules intermétalliques du type Zr(Nb,Fe)2, Zr(Fe,Cr,Nb) et (ZrNb)3Fe. La distance entre les particules est de 0,20 à 0,40 mum. Le procédé de fabrication susmentionné consiste à produire un lingot, à soumettre ledit lingot à un bêta-traitement préliminaire, à produire une ébauche en façonnant à chaud le lingot à la température à laquelle l'alpha-zirconium existe, à recuire l'ébauche à une température de 380 à 650 °C, à façonner l'ébauche à froid avec des étapes de recuisson intermittentes à la température à laquelle l'alpha-zirconium existe et à effectuer |
