Pseudo-binary Phase Diagram

This example using the TCS Ni-based Superalloys Database (TCNI) is a type of calculated isoplethal phase diagram section of a ternary system called a pseudo-binary, meaning that the section lies precisely in the plane of constant potentials (meaning along tie-lines). It is compared with literature data.
