# TTT Fit
The TTT Fit utility is another fitting utility used to fit for the diffusive phase transformation kinetics to the DANTE models using TTT curves. The TTT Curves can be generated from 3rd party software, or from experimental data.
## Use Case
Given the chemical composition from the experimental data file, the TTT Fit utility can fit for the kinetics of any phases. In this case, the experimental data was generated from the JMatPro software for ferrite.
The fitted plot can be seen below. Increasing the number of loops could possible increase the quality of the fit. The TTT Fit utility tool interpolates for the 1%, 10%, 20%, ... 99% fit.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://dante-solutions-inc.gitbook.io/dante-6.3-help-documentation/introduction-2/ttt-fit.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
