The X-ray laboratory is appareled with different equipment that uses fluorescence and X-ray diffraction techniques. These techniques are complementary and used in CENIM for the quantitative modification of both the elements and the phases that give them physical characteristics. Their use is essential in cutting-edge fields such as nanomaterials, high-entropy alloys, high-performance light alloys based on Mg, Al or Ti, new generation steels, biomaterials, recycling…

The tasks of Lab 189 will include the use of fluorescence and X-ray diffraction as essential techniques to control the quality and characterize the different materials that will be developed for application in additive manufacturing processes and the resulting materials after new manufacturing processes additive in metals. They allow to determine the chemical composition of the materials and to identify the crystalline phases present, respectively. In this way, any deviation from the desired chemical composition can be controlled, and the formation of unwanted phases can be determined by reaction between the different components during the different processing phases. In addition, in materials for health applications, these techniques will allow to dismiss the presence of toxic elements and phases that may react with tissue fluids.

On the other hand, the CENIM X-ray laboratory is the only lab in the Region of Madrid that has micro-fluorescence and X-ray diffraction equipment. In this way, composition and phase profiles can be made to evaluate the homogeneity of the different samples. Finally, as the processing methods to be used might in some cases lead to the presence of a strong crystallographic texture or introduce high residual stresses, they will be characterized by X-ray diffraction techniques.
