The 17th International Conference on MECHANICS, RESOURCE AND DIAGNOSTICS OF MATERIALS AND STRUCTURES (MRDMS 2023) Application of dynamic recrystallization physically based multilevel model to describe hot upsetting multistage process D. S. Bezverkhy and N. S. Kondratev* Perm National Research Polytechnic University, Laboratory of Multilevel Structural and Functional Materials, 29 Komsomolsky Ave., Perm, 614990, Russian The current problem is the mathematical modeling of technological processes, which are often multistage. This paper examines a multistage technological process of hot upsetting of a workpiece in the shape of a cube, taking into account dynamic recrystallization. The finite element software Abaqus is used to carry out calculations of multistage hot upset. Areas of the workpiece are identified for its detailed description using a multilevel model that takes into account dynamic recrystallization. The material considered is structural superalloy Inconel 690, widely used in aircraft engine construction, oil and gas and nuclear industries. © 2024 The Authors, Published by Elsevier B.V.

(2016), Akkuzin S. et al. (2021)). During the processes of pre-processing and manufacturing of product parts, the material structure changes significantly and affects the mechanical properties of the product (Gardner S. et al.
