Development of high strenght steels
Original language description
Innovative processing strategies of high-strength steels enable better combinations of strength and ductility than the classical ones. One of these new heat treatment methods is also quenching and partitioning (Q-P) process, which benefits from a positive effect of retained austenite on mechanical properties. Resulting microstructure after Q-P process consists of martensite with 5-15% of retained austenite, which allows it to achieve strengths above 1800MPa with ductility around 10%. In this work Q-P process was incorporated into the more complex thermo-mechanical treatment with incremental deformation, which refines final microstructure and thus further improves its mechanical properties, increasing the strength to 2000MPa without deteriorating the ductility. Three steels with 0.43%C and varying manganese (0.6-1.2%) and silicon (2-2.6%) content were used to investigate the influence of these main alloying elements. Important parameters of the process, such as cooling rate and partitio
