Abstract
Responsible parts of gas-turbine engines are made of nickel superalloys by the method of precise (precision) casting, also called investment casting. Removal of model compositions from shell molds is the most important stage of this technological process, which largely determines the quality of the finished casting. The article examines the features of the modern method of removing waxy model compositions, which is widely used in the domestic industry, using a boiler-autoclave in a medium of superheated water vapor.
