| The microstructure and mechanical behaviour of dual-phase steels are highly sensitive to the variation of the process (temperature of austeno-ferritic heat treatment). Online control by magnetic method is relevant to detect any fluctuation of the microstructure. The dual-phase is a steel composed of ferrite and martensite phases. Each phase can be considered as a sphere embedded in a homogeneous equivalent medium. The magnetic model used for each phase is based on a magneto-mechanical coupled model. This is an explicit single crystalline model representative of the behaviour of the corresponding phase. Localization rules allow the simulation of the average medium. Experiments are carried out and compared to the modelling. |
