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 partitioning hold were optimized with regard to the final microstructure and mechanical properties.
