The phase equilibrium diagram for the Fe-Nb-Tisystem

Microstructure analysis, differential thermal analysis, x-ray diffraction, and electron probe microanalysis have been applied to the phase equilibria in the Fe - Nb - Ti ternary system over the complete composition range. The 950 degrees C isothermal section of the diagram has been constructed. Positions have been determined for the monovariant transformation lines in the melting diagram. No ternary intertmetallides have been found.
