Binary Phase Diagrams
You can use the TCS Mo-based Alloys Database (TCMO) to plot binary phase diagrams in Thermo-Calc. Each binary system is critically assessed to reproduce the phase diagram and thermodynamic properties data available in the literature.
The CALPHAD Method and the Thermo‑Calc Databases. Also visit the video tutorials on our website or our YouTube playlist.
The examples shown here are important sub-systems of the Mo-Si-B based alloys. Mo3Si, Mo5Si3, and Ti5Si3 are also major phases that influence the performance of the Mo-Si-B based alloys.
