Thesis Title

Uncertainty quantification of interfacial energies in CALPHAD method

Research overview

Exploring interfacial energy's pivotal role in metal processing, particularly in cemented carbide
systems, is crucial. For instance, assessing the wettability of binder alloys becomes imperative
for 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 cemented
carbide systems due to enhanced wettability. This research aims to quantify uncertainties in
predicting interfacial energies using a combination of atomistic simulations and computational
thermodynamics. By justifying Mo's role in improving alloy wettability, this study facilitates the
development of alternative binders for Tungsten Carbide (WC) hard metals.
