A novel high-strength steel has been made through thermo-mechanical controlled processing with the finish rolling temperature of 750°C followed by air cooling. Subsequently, both partial austenitisation at 800°C and fully austenitisation at 930°C have been attempted for equal duration of 30min prior...
