Abstract

The phase equilibria in the Co–Fe–Zr ternary system were investigated by means of optical microscopy (OM), electron probe microanalysis (EPMA), X-ray diffraction (XRD), and differential scanning calorimetry (DSC) on equilibrated ternary alloys. Four isothermal sections of the Co–Fe–Zr ternary system at 1300 °C, 1200 °C, 1100 °C and 1000 °C were experimentally established. The experimental results indicate that (1) no ternary compound was found in this system; (2) the solubility of Fe in the liquid phase of the Co-rich corner at 1300 °C is extremely large; (3) the liquid phase in the Zr-rich corner and the (Co,Fe)2Zr phase form the continuous solid solutions from the Co–Zr side to the Fe–Zr side; (4) the solubility of Zr in the fcc (Co, Fe) phase is extremely small.

Research highlights► We determined four isothermal sections of the Co–Fe–Zr system from 1000 °C to 1300 °C. ► No ternary compound was found in the Co–Fe–Zr ternary system. ► The solubility of Fe in the liquid phase at 1300 °C is extremely large. ► The (Co, Fe)2Zr phase form the continuous solution from Co–Zr side to Fe–Zr side. ► The solubility of Zr in the fcc (Co, Fe) phase is extremely small.
