Viscosity, surface tension of liquid, thermal/electrical conductivity, and their composition and temperature dependence, are all important properties for modeling the AM process together with heat and heat capacity. While the treatment of heat and fluid flow is considered as state of the art in current FEM models, material properties are treated in a highly simplified manner. During the last few years new models to predict thermophysical material properties using the CALPHAD method have been developed and by adopting a unified treatment of both process parameters and alloy dependent thermophysical properties, there is the potential for more accurate solidification simulations for AM.
This presentation will describe how such an approach has been adopted to implement into Thermo-Calc a module for Additive Manufacturing. This combined approach can be thought of as an example of ICME (integrated computational materials engineering). Examples will be shown together with other ongoing/completed developments related to AM.
