摘要：
The hot torsional deformation of an austenitic Ni-Cr-Co-Nb-Ta-Mo superalloy is subjected to physical modeling. The influence of temperature-deformation parameters on the evolution of the alloy microstructure is studied, and the development of dynamic recrystallization as a function of these parameters is estimated. The results obtained can be used for developing and optimizing the conditions of hot plastic deformation of similar alloys.
