| Abstract Scope |
Hot rolling plays a critical role in achieving the final texture, microstructure, and magnetic properties of non-oriented electrical steels (NOES). NOES with and without austenite-to-ferrite phase transformation not only exhibit different high-temperature deformation behavior (i.e., due to the presence or absence of the harder austenite phase) but also develop different final textures and microstructures. In this study, the high-temperature deformation behavior was simulated using uniaxial compression in the range of 850-1050 °C and strain rates of 0.01-1 s⁻¹ for two NOES alloys: one with 1.3 wt.% Si (with phase transformation) and the other with 3.2 wt.% Si (without phase transformation). The presence of austenite in the low-Si NOES under the deformation conditions was evaluated using dilatometry. Furthermore, the critical strain required for the initiation of dynamic recrystallization was estimated and correlated with differences in deformation behavior. A microstructural study was conducted to establish the mechanisms of hardening/softening under the applied deformation conditions. |
