Conclusions

  1. 1.

    Nickel-chromium alloys with 20% Cr and 6–9.6% Nb undergo dispersional hardening.

  2. 2.

    At relatively low aging temperatures a highly dispersed body-centered Ni3Nb phase precipitates first from the solid solution; with increasing aging time this phase becomes a plate-like equilibrium phase of the same composition with a rhombic lattice.

  3. 3.

    The transformation of the highly dispersed excess phase into the plate-like phase induces a decrease of hardness in the alloy with 7.2% Nb and induces an increase of hardness in the alloy with 6% Nb (after prolonged heating).

  4. 4.

    The maximum heat resistance (at 700 and 750°C under a stress of 30 and 20 kg/mm2 respectively) of alloys of the Ni+20% Cr+Nb system is reached when the concentration of Nb is 7.2%.
