Add-on Databases

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

How to Update ThermoTech Databases to a New Version

Transferring TT databases from an older version of Thermo-Calc:

1. Install Thermo-Calc 2023b.
2. Open the Thermo-Calc data directory in the Thermo-Calc installations, both for 2023a and 2023b. The default paths for this are:
   Linux and Mac: Default path: /usr/local/thermocalc/<version>/data
   Windows: Default path: C:\program files\Thermo-Calc\<version>\data
3. Copy the TT database folder from 2023a to the database folder of Thermo-Calc 2023b.

How to Install ThermoTech Databases for the First Time

1. Download the TT database with the Link provided by Thermo-Calc Software upon purchase.
2. Open the Thermo-Calc data directory in the Thermo-Calc installations. The default path for this is:
   Linux and Mac: Default path: /usr/local/thermocalc/<version>/data
   Windows: Default path: C:\program files\Thermo-Calc\<version>\data
3. Make a new folder and give it the name of the purchased TT database (e.g. TTNI8, TTTIAL, TTTI3, TTZR1, etc…).
4.  Place the TT database (e.g. TTNI8setup.TDC, TTTIALsetup.TDC, TTTI3setup.TDC, etc…) into this folder.
5. You can verify, that the name you gave the folder is correct by opening the file tc_initd.tdb (also found in the data directory) with a text editor. This is the file Thermo-Calc uses to link the name of a database to its location.
