High-Strength Martensitic Steels with Low Ms Temperature

Popis výsledku v původním jazyce

Various novel heat treatment and thermomechanical treatment procedures have been developed recently in order to enhance mechanical properties of high-strength steels. These procedures rely on retained austenite in the microstructure to increase elongation, while keeping the high ultimate strength. One of these procedures is the Q&P process (Quenching and Partitioning). It produces martensite and retained austenite to obtain strengths of more than 2000 MPa and elongation levels of 10-15 %. The industrialapplication of this process is complicated by the need for quenching in the range between Ms and Mf. The Ms temperature normally lies in the 200-250 °C interval. This is why new steels with low Ms temperature were selected for the experimental programme. Thanks to this feature, the steels could be quenched in water or polymer-based baths. The primary alloying elements of these four selected steels were manganese, silicon, molybdenum and chromium. The development of the heat treatment se
