Ternary Systems
For the TCS Ti/TiAl-based Alloys Database (TCTI), these ternary system examples show the phase stabilities in two dimensional plots, isothermal or vertical sections. The ternary isothermal sections can be created in Thermo‑Calc using the TERNARY module in Console Mode and the Ternary Calculator in Graphical Mode.
Ti-Nb-Si

Figure 2: Calculated isothermal section of Ti-Nb-Si at 1773 K [1998Bew; 1994Sub].
Ti-C-Si
