Tata Steel and University of Cambridge Thermodynamic modelling of minority phases in EAF steels

This PhD opportunity focuses on thermodynamic modelling of minority phases in EAF (Electric Arc Furnace) steels. The transition to EAF steelmaking creates challenges for the reliable production of thin rolled steel products where residual element accumulation may compromise processability and properties. This PhD will utilise thermodynamic modelling to obtain predictions of equilibrium and, where possible, non-equilibrium phases for a matrix of compositions covering flat rolled products including elevated levels of Cu, Mo, Ni & Sn. Direct comparisons will be made with experimentally identified phases from high throughput samples. Subsequent characterisation will be performed using a combination of scanning transmission electron microscopy, X-ray diffraction and, where necessary, synchrotron X-ray diffraction, nano-secondary ion mass spectroscopy, and 3D atom probe tomography. The data acquired will be used to modify thermodynamic database parameters to improve the predictions. Training in all computational and experimental methods will be provided in the projects, although relevant previous experience would be advantageous.
