The development of steel with high specific strength is required for reducing vehicles’ weight and decrease of carbon dioxide emissions and fuel consumption. The most promising direction is the development of steels containing light elements such as manganese, aluminum, silicon, additionally alloyed with carbon. The final mechanical properties of these steels are affected by hot plastic deformation, which transforms the cast microstructure into a fine-grain one. Fe–30Mn–10Al–3Si–1C steel in the cast state was studied in this work. Compression tests were carried out in the range of strain rates of 0.1, 1, and 10 s-1 and temperatures of 900–1100 °C on the Gleeble 3800 thermomechanical simulator. The models of the relationship of flow stress and grain size with hot plastic deformation parameters were constructed. These models can be used to develop and optimize technologies for hot plastic deformation of Fe–30Mn–10Al–3Si–1C steel. The studied steel has a high level of hardness after hot deformation in the temperature range of 1000–1050 °C due to the formation of a fine grain microstructure, which can guarantee a high specific strength of the final products obtained using optimized hot plastic deformation modes.
