Chemo-mechanical phase-field modeling of iron oxide reduction with hydrogen


Iron oxide reduction with carbon or carbon monoxide for the manufacturing of iron and steel accounts for over 25% of CO2 emissions. As an alternative, hydrogen attracts lots of interesting in iron oxide reduction.  Reduction of iron oxide (in the form of Fe2O3) involves phase transformations, which can further  influence  the stress state, mechanical behavior, and local reaction/transformation rates.  In this work, a chemo-mechanically coupled phase-field (PF) model is developed to investigate the chemo-mechanical interplay during the reduction, and its impact on the reduction profile.


Dr.rer.nat. Yang Bai received his doctoral degree (2020) in the department of materials science from TU Darmstadt, and master’s degree (2016) in solid mechanics from Beijing Institute of Technology, and bachelor’s degree (2013) from Peking University, China. He is the postdoc of Computational Sustainable Metallurgy group at Max-Planck-Institut für Eisenforschung (MPIE). His research interests focus on the phase-field method, solid mechanics, multiphysics coupling, and materials simulation.
