CRC/TRR 270: Project B7

The common goal is to develop new magnetic materials for efficient energy technologies.

This requires a detailed understanding of the structural, magnetic and electronic interactions within the material in order to adjust the local and global properties through newly developed processing techniques such as additive manufacturing and strong plastic deformation methods.

The overall goal of this project is to use computer simulations for predicting the interplay of nanophase formation, resulting microstructure and magnetocaloric properties of Fe-based rare-earth free materials. We will initially explore the influence of laser powder bed fusion (LPBF)-process parameters on the early stage of nanophase formation with a focus on binary Fe-X alloys as model systems. For various nanoarchitectures, we will study the heat transport by non-equilibrium molecular dynamics (MD)-simulations and investigate the role of interface phenomena in order to predict optimal microstructures. Further, we plan to develop effective Hamiltonians, which allow to directly predict the magnetocaloric response.

Project period: 01-01-2020 – 31-12-2023
