The Jominy Predictor Utility uses the DANTE phase transformation kinetics model to predict the hardness and microstructural profiles for a Jominy end quench test. This utility can be used to compare with actual experimental data to adjust the phase transformation kinetics within the DANTE material database.

## Use Case

The Jominy Predictor utility outputs the hardness and phase volume fractions based off of a Jominy end quench test. This utility can be used to modify the material parameters inside the DANTE material database to match experimental results.

Next, we can adjust the Martensite and Bainite transformation kinetics to adjust the amount of volume fraction for each phase. By adjusting the values, the amount of bainite increased.

If experimental data is available, using this technique can increase the accuracy of the phase transformation kinetics which will lead to more accurate thermal and stress analysis.
