The paper is devoted to the study of the material’s condition of guide blades made of heat-resistant nickel alloy with different operating time. It is established that the structure of the blade material and their mechanical properties are not satisfactory for further operation. To recovery the performance properties and structure of the blade material, several types of heat treatment were tested and the optimal one was chosen. The complex parameter of strength and plasticity is calculated and on its basis the estimation of degree of recovery of blade’ material after heat treatment is carried out.
