Abstract

The paper summarizes the history of the development of technology of directional crystallization and melting and pouring equipment for the production of blades of gas turbine engines from heat-resistant alloys with directional and single-crystal structure in Russia and abroad. It is shown how the conditions of directed crystallization affect the structure of Nickel heat-resistant alloys. The characteristics of industrial plants developed in FSUE «VIAM» with a computer system for controlling the parameters of the technological process, as well as the ways of their further development are given.
