<p>This study investigates the microstructural evolution, dynamic softening behavior, and strain distribution effects during hot deformation of 2507 super duplex stainless steel. The research highlights the interaction between ferrite and austenite phases and their critical influence on the material's thermomechanical processing performance. Key findings reveal significant differences in softening behavior between the two phases, with <i>δ</i>-iron exhibiting superior thermal ductility due to its lower stacking fault energy compared to <i>γ</i>-austenite, which shows more pronounced strain hardening under similar conditions. The study further demonstrates that the distribution of strain across the material significantly affects microstructural evolution. Regions subjected to higher strains experience increased grain refinement and dislocation density, while areas with lower strains retain coarser grains and lower defect densities. These observations underscore the importance of achieving uniform strain distribution to ensure balanced microstructural evolution and improved mechanical properties. Additionally, the research emphasizes that asymmetric strain distributions can lead to localized stress concentrations at phase interfaces, potentially degrading material performance. To enhance thermomechanical processing stability, it is recommended to optimize strain distribution across deformation passes, particularly by balancing the strain applied to <i>δ</i>-iron and <i>γ</i>-austenite phases. This approach ensures uniform microstructural evolution, reduces macroscopic non-uniformity, and ultimately improves the mechanical characteristics of 2507 super duplex stainless steel.</p>
