9%Cr tempered martensitic steels are currently used in fossil power and in petrochemical plants. Due to attractive properties and manufacturing costs, there are also potential candidates for structural components of new generation nuclear reactors. To optimize their high temperatures mechanical properties (~500-650°C), a thermal-mechanical treatment based on “ausforming” is being considered. It is composed of an austenitization step, followed by warm-rolling of metastable austenite at intermediate temperatures (500-600°C), then quenching and tempering. This study aims at understanding the effects of each of these steps, and particularly the warm-rolling of the metastable austenite, on the resulting microstructure and mechanical properties.A...
