description: The research set the following goals:
1. Analysis of the literary sources on the features of structure formation high-strength austenitic steel during high-temperature thermomechanical processing.
2. Studying the mechanical and physical properties of sheet metal after deformation according to two different schemes.
3. Studying the microstructure and fractures of samples.
4. Choose the optimal thermal deformation scheme, based on the obtained results.
The microstructure of the samples was studied, using electron microscopy, were determined the possible causes of unsatisfactory toughness values. Was determined the physical and mechanical properties of sheet metal. As a result, the optimal treatment mode for thermal deformation was selected, which ensures the achievement of the desired properties.
