Abstract

Heat-resistant nickel alloys are materials used to manufacture a wide range of gas turbine engine parts. The level of refractory strength of the heat-resistant nickel alloys is determined by their chemical and phase composition, as well as by the manufacturing techniques used, which ensure the formation of a given material structure. An important factor in the industrial production of the heat-resistant nickel alloys and in the development of new-generation alloys is the ability to control the chemical composition of the cast bar stock and finished products from the heat-resistant nickel alloys by modern methods of spectral analysis. The development of a set of methods for measuring the mass fraction of elements in heat-resistant nickel alloys by mass spectrometry with inductively coupled plasma, optical emission and X-ray fluorescence analysis, makes it possible to control the content of alloying and microalloying elements and various impurities.
