Quantitative analysis of textures produced in a hot-extruded zirconium plate; Analyse quantitative des textures developpees dans une plaque de zirconium filee a chaud

Abstract

The textures produced in zirconium by the extrusion at 730 deg C of a cylindrical billet in the form of a plate having a rectangular cross-section, have been studied by the Schulz method using an isotropic standard. These textures have been determined both parallel to the plane of the plate and parallel to the plane of the sides, All the results are analyzed in a final discussion which makes it possible to show, in particular near the edges of the plate, that certain components of the textures observed in the two series of recordings are in fact aspects of the same texture seen from two different angles, It is shown furthermore that the zirconium thus shaped has cold-work textures and als recrystallisation textures formed after the preceding cold-working, If the observed textures are considered schematically, it can be see that two of these have already been described in the literature and are similar to those found in rolled products: these textures are such that the (0001) planes are inclined at 36 deg C and 60 deg C respectively with respect to a plan tangential to the curve (envelope of transverse flow rates) resulting from the extrusion geometry under consideration; the  More>>

The direction of extrusion associated with these planes and common to the three textures is of the type <1010>, Dilatometric tests have been carried out on samples taken both parallel and perpendicular to the extrusion direction, These tests show that the zirconium is dilatometrically anisotropic and that a plot of ({alpha}{sub v})-a against temperature shows a change of gradient at 400 deg C, this latter effect may be due to the change in the electronic configuration of the metal occurring at this temperature. (author) [French] Les textures conferees au zirconium par filage a chaud a 730 deg C d'une billette cylindrique sous forme d'une plaque de section rectangulaire, ont ete etudiees par la methode de Schulz en se referant a un etalon isotrope. Ces textures ont. ete determinees soit parallelement au plan de la plaque, soit parallelement au plan des rives. Tous les resultats sont analyses dans une discussion finale qui permet, en particulier au voisinage des aretes de la plaque, de montrer que certaines composantes des textures observees clans les deux series d'enregistrements, sont en fait l'expression de la meme texture vue sous deux angles differents. D'autre part. it est montre que le zirconium ainsi mis en forme comporte des textures d'ecrouissage et de recristallisation posterieure a l'ecrouissage precedent. En schematisant l'ensemble des textures determinees, on observe trois textures dont deux deja signalees dans la bibliographie et comparable a celles des produits lamines: ces textures sont telles que les plans. (0001 presentent des inclinaisons respectives de 36 deg C et 60 deg C par rapport a un plan tangent a la courbe (enveloppe des vitesses d'ecoulement transverse) resulant de la geometrie du filage considere; la troisieme texture est definie par le fait que le plan (0001) est orthogonal aux surfaces exterieures de la plaque. La direction de filage associee a ces plans et commune aux trois textures est du type <1010>. Des essais dilatometriques ont ete effectues sur des echantillons preleves dans le sens du filage et clans le sens transverse. Ces essais mettent en evidence l'anisotropie dilatometrique du zirconium ainsi qu'un changement de pente de la courbe ({alpha}{sub v}){sub a} en fonction de la temperature a partir de 400 drg C, pouvant etre explique par la variation de la configuration electronique du metal a partir de cette temperature.
