X-ray fluorescence analysis of the elemental composition of Titanium metal waste

The purpose of this work was to conduct X-ray fluorescence analysis of the elemental composition of a sample of metal waste and determine the alloy grade, primarily titanium, planned for processing by electrical discharge dispersion to produce powder suitable for additive manufacturing. Methods. To determine the elemental composition of a titanium-containing alloy of unknown grade, a metal plate sample measuring 530 mm in length, 144 mm in width, and 4 mm in thickness was collected. Analysis was performed using a Niton XL3t portable X-ray fluorescence spectrometer. Before measurements, the sample surface was cleaned, and each point was analyzed at least three times to enhance reliability. X-ray fluorescence analysis provides rapid and nondestructive determination of the elemental composition of complex materials without the use of reference samples, enabling localized spot analysis with high accuracy and speed (up to 10 seconds), which is especially important when studying potentially heterogeneous objects. The design features of the Niton XL3t instrument enable localized spot analysis of the surface of the test objects, which is crucial when working with materials potentially characterized by structural or chemical heterogeneity. To determine whether the actual chemical composition complies with the regulatory requirements specified in the steel grade list and GOST 19807–91, a comparison was made between the experimentally determined concentrations of elements and the theoretical composition of the alloy. Results. X-ray fluorescence analysis of the elemental composition of titanium-containing metal waste using a Niton XL3t portable spectrometer reliably established that the sample corresponds to the VT1-2 alloy grade. Conclusion. The obtained results form the scientific and methodological basis for subsequent research on the processing of these metal wastes using electrical discharge dispersion to produce spherical powders applicable in additive manufacturing.
