Abstract

The article presentsan overview of materials related to the technological process of production of modern model compositions for casting ofcritical parts of gas turbine engines from nickel superalloys made by the National Research Center «Kurchatov Institute» – VIAM. The general characteristics of model compositions are considered, including the composition and basic requirements for them, as well as issues of the activity of the manufacturing area established in the mid-2010s and producing a wide range of high-quality model compositions based on domestic raw materials.
