Abstract Scope |
During the last years, Thermo-Calc has developed new models to predict thermophysical material properties using the CALPHAD method with unprecedented accuracy.
While the treatment of heat and fluid flow is state of the art in current FEM models, material properties are treated in a highly simplified manner. This gives us the unique possibility to address the solidification problem during AM with the focus on a unified treatment of both process parameters and also alloy dependent thermophysical properties. A new Module for Additive Manufacturing, using this approach, was implemented in 2023b release. In addition, results from transient simulations can be automatically transferred to Precipitation and Diffusion Module to evaluate location specific properties. This combined approach can be thought of as an example of ICME. Examples will be shown together with other ongoing/completed developments related to AM which includes key-holing prediction and process maps thru TC-Python. |
