Conclusions

  1. 1.

    The isothermal section of the Hf-Mo-C ternary system at 1400°C has been constructed.

  2. 2.

    The features distinguishing the phase equilibria at 1400°C from those in the 1700°C section are the decomposition of the binary carbide η-MoC1−x, its stabilization in the ternary system, resulting in the appearance of (γ + C) and (γ + η + C) fields, and a substantial widening of the (λ2 + β2 + 6) and (β2 + δ + α) fields, caused by the (β2 + 6) field.

  3. 3.

    The extent of the homogeneity field of the phase based on the cubic carbides (Mo, Hf)C1−x differs little, as regards both hafnium and molybdenum contents, from that at 1700°C.
