Abstract
(DE)
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Bestimmen der Werkstoffeigenschaften eines polykristallinen, insbesondere metallischen Produkts (1) während einer Herstellung oder Qualitätskontrolle des polykristallinen, insbesondere metallischen Produkts (1) mittels Röntgenstrahlenbeugung unter Verwendung von wenigstens einer Röntgenquelle (11) und wenigstens eines Röntgendetektors (13). Hierbei wird eine von der Röntgenquelle (11) erzeugte Röntgenstrahlung (15) auf eine Oberfläche (2) des polykristallinen Produkts (1) gerichtet und das hieraus resultierende Beugungsbild (16) der Röntgenstrahlung (15) von dem Röntgendetektor (13) aufgenommen. Nach dem Austreten aus der Röntgenquelle (11) wird die Röntgenstrahlung (15) durch einen Röntgenspiegel (17) geleitet, wobei die Röntgenstrahlung (15) durch den Röntgenspiegel (17) sowohl monochromatisiert als auch in Richtung des polykristallinen Produkts (1) und/oder des Röntgendetektors (13) fokussiert wird und anschließend auf einer Oberfläche (2) des metallischen Produkts (1) auftrifft.
(EN)
The invention relates to a method and an apparatus for determining the material properties of a polycrystalline, in particular metallic, product (1) during the production or quality control of the polycrystalline, in particular metallic, product (1), by means of x-ray diffraction using at least one x-ray source (11) and at least one x-ray detector (13). X-ray radiation (15) generated by the x-ray source (11) is directed at a surface (2) of the polycrystalline product (1) and the diffraction image (16) of the x-ray radiation (15) resulting therefrom is recorded by the x-ray detector (13). After exiting the x-ray source (11), the x-ray radiation (15) is guided by an x-ray mirror (17), wherein the x-ray radiation (15) is focused both monochromatically and in the direction of the polycrystalline product (1) and/or of the x-ray detector (13) by the x-ray mirror (17) and said x-ray radiation subsequently impinges on a surface (2) of the metallic product (1).
(FR)
L'invention concerne un procédé et un dispositif de détermination des propriétés de matériau d'un produit (1) polycristallin, notamment métallique, pendant la production ou le contrôle de qualité du produit (1) polycristallin, notamment métallique, au moyen de la diffraction des rayons X en utilisant au moins une source de rayons X (11) et au moins un détecteur de rayons X (13). Un rayonnement X (15), généré par la source de rayons X (11), est ici dirigé sur une surface (2) du produit polycristallin (1) et l'image de diffraction résultante (16) du rayonnement X (15) est enregistrée par le détecteur de rayons X (13). Après être sorti de la source de rayons X (11), le rayonnement X (15) est guidé à travers un miroir à rayons X (17), le rayonnement X (15) étant à la fois rendu monochrome et focalisé dans la direction du produit polycristallin (1) et/ou du détecteur de rayons X (13) par le miroir à rayons X (17), et venant ensuite frapper une surface (2) du produit métallique (1).
