Originální abstrakt

During operational conditions of internal combustion turbines of turbojet engines, the impeller blades are stressed by load cycles which vary in time, temperature and stress. In the course of operation, the blades are exposed to a considerable number of degradation effects, particularly high-temperature corrosion, fatigue processes and creep. Operational conditions of heat parts, used in gas turbines and turbo-compressors, were simulated by creep tests of Inconel 713 LC nickel superalloy during a constant load of temperatures ranging from 750 up to 950C. Changes in the structure dependent upon time, temperature and stress applied were analysed by means of light and electron microscopy methods after the fracture of test bars.
