Microstructural evolution and strength-toughness behavior of fire-resistant steel under thermo-mechanical controlled processing

Fire-resistant steels are engineered to retain high strength at elevated temperatures, typically maintaining a yield strength (YS) ratio (600 °C/RT) above 0.67 to prevent sudden structural collapse during fire exposure. Although achieving such strength retention is critical, ensuring sufficient frac...
