Abstract

This work is devoted to the issues of comparison of domestic and foreign standard samples (certified reference materials) of nickel alloys of various grades. Using the method of x-ray fluorescence spectrometry on sets of State standard samples of alloys VZh172 and VZhL21 containing elements such as Al, Co, Cr, Mo, Ti, W, Zr, Fe, Mn, calibration dependences of the mass fraction of elements on the intensity of the signal – the characteristicx-ray radiation. Using statistical techniques, an assessment was made of the possibility of joint use of sets in the construction of general calibration characteristics for the simultaneous determination of Al, Co, Cr, Mo, Nb, Ta, Ti, W, Zr, Fe, Mn in nickel alloys of similar composition.
