TTT Fit

Fit diffusive phase transformation kinetics to build accurate TTT-based material models.

Fit TTT Curves to DANTE’s Phase Transformation Models

TTT Fit enables engineers to calibrate diffusive transformation kinetics directly from Time-Temperature-Transformation (TTT) data. Whether your curves come from experiments, literature, or 3rd-party software, TTT Fit produces accurate phase transformation parameters for use in DANTE simulations.

Precise Fitting of Diffusive Transformation Kinetics

TTT Fit is designed to generate accurate DANTE material parameters by fitting real or generated TTT curves. This allows metallurgists and engineers to define diffusive phase transformation behavior—such as ferrite, pearlite, and bainite formation—with precision before running heat treatment simulations.

Users can load time-temperature-phase data, set parameter bounds, select the fitting method, and iterate through fitting loops to obtain the best model match.
