Vercruysse, Florian (author), Celada-Casero, Carola (author), Linke, Bernd M. (author), Verleysen, Patricia (author), Petrov, R.H. (author)Because of their excellent combination of strength and ductility, quenching and partitioning (Q & P) steels have a great chance of being added to the third generation of advanced high strength steels. The large ductility of Q & P steels arises from the presence of 10% to 15% of retained austenite which postpones necking due to the...journal article 2020
