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.
