description: The topic of the final qualification work: Study of recrystallization during hot deformation of a heat-resistant alloy of the Ni-Cr-Co-Mo system. This work is devoted to the study of recrystallization during hot deformation of a turbine blade by constructing a mathematical model of the stress-strain state and comparing the data of the model with the data of physical modeling of the process of hot plastic deformation of a heat-resistant alloy of the Ni-Cr-Co-Mo system. Tasks that were solved in the course of the study: 1. On the basis of processing the data of physical modeling of the process of hot plastic deformation of a heat-resistant alloy of the Ni-Cr-Co-Mo system, special recrystallization diagrams were constructed. 2. Using finite element modeling and the DEFORM program, a mathematical model of the stress-strain state was developed. 3. The implementation of data from the constructed recrystallization diagrams and the stress-strain state model makes it possible to predict the distribution of the grain structure over the cross section of the finished product and, accordingly, theÂ mechanical and service properties of the product from the alloy under study obtained using hot plastic shaping. Physical modeling in combination with the use of the finite element method makes it possible to effectively assess the stress-strain state during hot plastic deformation of products with a complex cross-sectional profile and optimize the process of hot plastic shaping. Simulation of dynamic recrystallization makes it possible to control the process of structure formation during hot plastic deformation.
