Abstract

The paper presents the results of the application of experimental and computational methods for studying the thermal conditions of the process of directed crystallization of heatresistant alloys, which have found wide application in the production of blades for modern aviation
gas turbine engines made of heat-resistant alloys. Methods for estimating the values of the temperature gradient, the crystallization rate, the size of the liquid-solid zone at the crystallization front, and their effect on the structure and properties of superalloys are proposed and implemented
