Summary

The systems Nb-Re-C and Ta-Re-C were investigated by the methods of x-ray and metallographic analyses. The phase equilibria in these systems at 1800°C were determined (Figs. 1 and 3). In the ascast high-rhenium alloys, a metastableϑ -phase was detected. Theϑ -phase could not be obtained in the pure form; this phase is in equilibrium with NbC and TaC. Theσ -phase does not exist in the system Ta-Re at 1800°C.
