2. The tensile strength of the steel improved with decreasing FA temperature. Notably, the steel annealed at 1000 °C demonstrated a yield strength (YS) of 340 MPa and a tensile strength (TS) of 750 MPa, along with an impressive ductility of 106%. This exceptional combination of strength and ductility underscores the effectiveness of the FH process in optimizing the mechanical properties of the material. Acknowledgements The authors would like to extend their sincere gratitude to Juha Uusitalo, operator of the Gleeble 3800 thermo mechanical simulator, for his valuable assistance in conducting the experimental FH cycles. We also wish to thank the FMT group at the Kerttu Saalasti Institute for their support in funding the EBSD experiments.
