Binary Phase Diagrams

You can use the TCS Mg-based Alloys Database (TCMG) to plot binary phase diagrams in Thermo‑Calc. These examples show a selection of the important assessed systems that are the building blocks of the database itself when applying the CALPHAD method.

The CALPHAD Method and the Thermo‑Calc Databases. Also visit the video tutorials on our website or our YouTube playlist.

When working in Thermo‑Calc with binary diagrams you use either the Binary Calculator (in Graphical Mode) or the Binary module (in Console Mode). The fundamental calculation engine is the same but you access the settings in different ways.
