    Main objectives of the team

    From solidification processes are issued the first materials microstructures, inherited by the subsequent forming processes. It is of paramount importance to follow the thermomechanical history along the entire material forming route to understand, master and optimize the features of solidification microstructures, including the nature, the morphologies and the dimensions of thermodynamic phases. Similarly, the microstructure plays a key role on the thermomechanical history during solidification processing. The formation of numerous casting defects involves coupling between thermomechanics and microstructures. The studies of the team are combined at several scales and include the consequences of solidification microstructures on solid state phase transformations and properties of components.
