Stabilization of Retained Austenite in High-Strength Martensitic Steels with Reduced Ms Temperature
Original language description
Today's advanced steels are required to possess high strength and ductility. One way of achieving a favourable ductility level and a very high ultimate strength is to stabilise retained austenite in martensitic matrix. Among heat treatment processes capable of producing such microstructure, there is the Q&P proces (Quenching and Partitioning). It can produce microstructures consisting of martensite and a certain amount of retained austenite, which exhibit strengths above 2000MPa and elongation levels of10-15%. For some processes, it is appropriate to depress the Ms and Mf temperatures and modify the ferritic and pearlitic transformations to occur at lower cooling rates. By choosing an appropriate steel chemistry, the retained austenite can be stabilized in martensitic matrix at lower temperatures than in the ordinary Q&P process. Four steels were selected for the present experimental programme. Several heat treatment sequences were tried with these steels and multiple parameters were
