Ternary Isothermal Phase Diagram Sections
Many ternary systems pertaining to Ni-base superalloys are assessed to fit experimental data available in literature. These examples using the TCS Ni-based Superalloys Database (TCNI) are of calculated ternary isothermal phase diagram sections.
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 ternary diagrams you use either the Ternary Calculator (in Graphical Mode) or the Ternary module (in Console Mode). The fundamental calculation engine is the same but you access the settings in different ways.
