A Ternary Phase-Field Model Incorporating Commercial CALPHAD Software (Preprint)
Abstract
A ternary phase-field model was developed that is linked directly to commercial CALPHAD software to provide quantitative thermodynamic driving forces. A recently available diffusion mobility database for ordered phases is also implemented to give a better description of the diffusion behavior in alloys. Because the targeted application of this model is the study of precipitation in Ni-based superalloys, a Ni-A1-Cr model alloy was constructed. A detailed description of this model is given in the paper.
