description: This work is devoted to the development of a method for modeling the thermal fatigue of gas turbine engine blades based on the use of corselet samples in order to further evaluate its effect on the durability and the amount of plastic deformation depending on the temperature ranges of thermal cycling. Tasks that were solved in the course of the study: 1. The analysis of methods for modeling the thermal fatigue of products operating under conditions of cyclic temperature changes is carried out; 2. Installation and adjustment of the installation for thermocyclic tests, which ensures the implementation of tests in conditions close to the actual operating conditions of the nozzle and working blades of the gas turbine engine, has been carried out; 3. On the mounted experimental setup and on the Gleeble-3800 modular complex, thermocyclic tests of samples of various shapes and compositions in several temperature ranges were carried out, and the number of heating-cooling cycles up to the destruction of samples made of ZhS32 and VZhM5U alloys has been established; 4. The value of plastic deformation occurring in the heating-cooling cycles in samples of different shapes made of ZhS32 and VZhM5U alloys has been estimated. Based on the results obtained, it is concluded that the temperature range of the thermocyclic test affects the number of cycles before the formation of the main crack in the sample. The analysis of the obtained experimental data, as well as the theoretical calculation of the value of plastic deformation in samples of various shapes made of ZhS32 and VZHM5U alloys in several temperature ranges showed that the shape of the sample significantly affects its durability during thermal cycling.
