About the Diffusion Module (DICTRA)
The Diffusion Module (DICTRA) is an Add-on Module to Thermo-Calc that makes modeling multicomponent diffusion-controlled transformations simple and accessible. The Diffusion Module (DICTRA) is based on the numerical solution of the multicomponent diffusion equations and the CALPHAD approach.
