Abstract: A method and a device for determining the material properties of a polycrystalline, in particular metallic, product during production or quality control of the polycrystalline, in particular metallic, product by means of X-ray diffraction using at least one X-ray source and at least one X-ray detector. In this case, an X-ray generated by the X-ray source is directed onto a surface of the polycrystalline product and the resulting diffraction image of the X-ray is recorded by the X-ray detector. After exiting the X-ray source, the X-ray is passed through an X-ray mirror, wherein the X-ray is both monochromatized and focused, by the X-ray mirror, in the direction of the polycrystalline product and/or the X-ray detector, and then reaches a surface of the metallic product.

Abstract: The invention relates to a method for the heat treatment of a metallic product (P), in particular a strip or sheet, in which the product (P) is controlled and/or regulated by means of a control and/or regulating device (100) controlled and/or regulated furnace device (110) is carried out at a predetermined speed in a conveying direction (F), the product (P) being heated up to a first point (I) and then up to a second location (H) or is cooled down to a third location (III). The method according to the invention is characterized in that an austenite content of the product P is predicted for the second location (H) or for the third location (III) and it is then checked whether this austenite proportion is within a desired target range, in which case If a deviation from this is found, for example a zone temperature of the furnace device 110 is adjusted and preferably regulated in such a way that the austenite proportion of the product P predicted for the second location (II) or for the third location (III) is within a desired quality window for the target value of the austenite content.
