The graph method can be used for the determination of phase equilibria in multi-component systems. The determination of phase equilibria in an n-component phase diagram using the graph method can be realized on the basis of data on the phase equilibria in (n-1)-component systems. The phase diagrams of the five-component system Ni-Re-V-Cr-Mo at 1425 K, six-component system Ni-Mn-V-Cr-Mo-W at 1225-1250 K and seven-component system Ni-V-Nb-Ta-Cr-Mo-W at 1375 K have been investigated. All four-component equilibria in these systems have been determined by experimental investigation. Isothermal cross-sections have been constructed for all systems.
