Conclusions

  1. 1.

    Treatments II and III increase the heat resistance up to the softening temperature (700°C for the KhN77MVTYuB alloy and 750°C for the KhN70MVTYuB alloy).

  2. 2.

    Treatment III is preferable to treatment II. Treatment II increases the deformability, decreases the sensitivity to notches, and the intragranular tendency to crack persists up to higher temperatures.

  3. 3.

    Treatment II is easy to apply to machine parts and is carried out by ordinary technological processes, and is therefore more economical and more advantageous for commercial applications.

  4. 4.

    For alloys which are subjected to higher temperatures (700–800°C) in operation it is not logical to carry out intermediate deformation in the hardening process.
