669.017.13.1′293′295 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°C isothermal section of the diagram has been constructed. Positions have been determined for the monovariant transformation lines in the melting diagram. No ternary intermetallides have been found.
