Influence of Metastable Retained Austenite on Macro and Micromechanical Properties of Steel Processed by the Q-P Process

Original language description

By stabilising metastable austenite with a suitable morphology in a martensitic structure, it is possible to impart to multi-phase steels high ductility combined with tensile strengths exceeding 2000 MPa. One way to achieve such mixed structures consisting of martensite and retained austenite (RA) is the Q&P (quenching and partitioning) process. The resulting structure contains metastable austenite in the form of thin foils located between martensite laths or plates. The stability of austenite under mechanical load- ing is the essential factor contributing to the extraordinary plasticity of such materials during cold defor- mation. A steel with 0.43% of carbon, alloyed with manganese, silicon and chromium was chosen for the experiment described in thepresent paper. Using the Q&P process, a martensitic structure with 20% of retained austenite was obtained. As cold plastic deformation causes the austenite to transform, 10% cold deformation was applied after the Q&P process. This deforma
