Abstract

Gas turbine engine parts are made of nickel superalloys by die casting. One of the most important technological stages of this process, which largely determines the quality of the finished casting, is the removal of model masses from shell molds. The review examines the advantages and disadvantages of various methods of removing model compounds, as well as the main trends of domestic scientific research studies aimed at intensifying the process, reducing the possibility of cracks formation in molds and casting defects.
