Conclusions

The system W-Re-C was studied by the method of x-ray structural analysis. Phase equilibria were established for as-cast alloys and alloys quenched from 2000, 1500, 1000, and 800°C. Rhenium and α-W2C form continuous series of solid solutions. Forthe composition W3Re2C, there exists a ternary compound with a cubic structure which is related to the β-Mn structure (space group P41 3-O7, a=6.859±0.002 A). At temperatures above 2500°C, there exists the ternary carbide (W, Re)C, which has a cubic face-centered NaCl type structure (space group Fm3m-O 5h , a==4.063± 0.001 A). Preliminary data were obtained on the existence of a rhombic low-temperature W2C modification.
