  • The principal tasks of the researcher will be the following: • Participate to bainite and martensite transformation modeling (kinetics and microstructure) as well as all the associated tempering mechanisms (transition carbide/cementite precipitation, carbon segregations, stress relaxation, dislocation recovery) 1,2. Once developed and calibrated on experimental data from the literature and produced in the course of the project, these sub-models should be implemented in the Finite Element process framework of LTU to predict the microstructure and properties on realistic full-scale parts 3,4. • Help understanding and modeling the mechanical properties of the studied microstructure with respect to the observed microstructure evolutions (microstructure -based mean field models) 5. • The researcher could contribute also to the insitu HEXRD experiments and their analysis 6. • Contribute to the dissemination of the results (regular meetings, publications, conferences).

    The mission of the researcher is to conduct research in physical metallurgy at IJL in the frame of the RFCS project MIPRE.

    The Institut Jean Lamour (IJL) is a joint research unit of the CNRS and the University of Lorraine. The IJL has about 500 members including researchers, teacher-researchers, engineering, technical and administrative staff, doctoral students and post-doctoral fellows, and hosts about 80 internships per year. It collaborates with more than 150 industrial partners and its academic collaborations are deployed in some 30 countries. Its exceptional instrumental park is spread over 4 sites, the main one being a new building located on the Artem campus in Nancy. The study will be carried out within the 303 "Microstructures and Constraints" team on the RFCS MIPRE project. L'étude sera réalisée au sein de l'équipe 303 « Microstructures et Contraintes » sur le projet RFCS MIPRE.

    Eligibility criteria

    • The researcher should have good ability to work as a team, in a multicultural and international environment and integrate into a collaborative project involving industrial partners • Experience in phase transformation modeling in metallic alloys (displacive transformations in particular) is requested • Knowledge in physical metallurgy (deformation mechanisms, phase transformation, microstructure mechanics) would be necessary to conduct the project • Experience in micromechanical modeling would be an advantage
