ABSTRACT
During the last decade, the global air trafc has been growing rapidly. This caused the growth in the production of modern liners. There is a tendency to reduce the exploitation costs, including the amount of fuel being used. Simultaneously, more restricted requirements in the area of environment protection are being introduced, which involves a reduction of the amount of noxious substances formed during combustion of fuel. One of the essential development directions in aircraft engine construction is raising the combustion temperature, which increases the efciency, and reduction of the amount of noxious substances being created. This determines the usage of high temperatureresistant and creep-resisting materials with complex chemical composition and sophisticated microstructure, for elements of the hot parts of aircraft engines, for example, turbine blades.
