Add-on Databases

This page has instructions on how to install ThermoTech databases, denoted TT—, to a new Thermo-Calc 2023a installation.

Note that for version 2019a and newer, it will no longer be possible to copy the TT-databases from the installation of Thermo-Calc 2018b or older.

3. Copy the TT database folder from 2022b to the database folder of Thermo-Calc 2023a.
