摘要: The purpose of the present research is to study martensitic transformation in 22MnB5 steel under thermomechanical conditions by means dilatation data. To reach this aim, effects deformation temperature and strain rate on as well martensite start (Ms) were investigated. Thermomechanical treatments performed a dilatometer including isothermal samples range 550–9008C up final 0.5 three rates 0.1, 1, 10s � 1 . Finally, temperatures divided into two regimes lower higher than 8008C. In former, strain-induced phase transformations, while latter, occurrence dynamic recovery against mechanical stabilization austenite influenced transformation.
