Thesis title
Uncertainty quantification of interfacial energies in CALPHAD method
Research overview
Exploring interfacial energy's pivotal role in metal processing, particularly in cemented carbidesystems, is crucial. For instance, assessing the wettability of binder alloys becomes imperativefor developing alternatives to carcinogenic cobalt metal binders. Our prior CalPhaD method-based study revealed that an Fe-Ni-Co-Mo alloy could potentially replace Co in cementedcarbide systems due to enhanced wettability. This research aims to quantify uncertainties inpredicting interfacial energies using a combination of atomistic simulations and computationalthermodynamics. By justifying Mo's role in improving alloy wettability, this study facilitates thedevelopment of alternative binders for Tungsten Carbide (WC) hard metals.
