Abstract

The paper presents technological methods for manufacturing disks with functionally gradient characteristics from heat-resistant nickel alloys for parts of aircraft gas turbine engines. As a result of the analysis of the works, it has been determined that such materials can be obtained by pressure welding during hot processing, the technology of granule metallurgy and regulated recrystallization of grains as a result of heat treatment. One of the alternative methods for obtaining such materials is the manufacture of metal composite materials.
