Conclusions

  1. 1.

    Alloying with tantalum, which strengthens both the solid solution and the intermetallic γ′ phase, substantially increases the heat resistance of nickel alloys.

  2. 2.

    The additional strengthening of alloys with tantalum is due to formation of primary ductile tantalum monocarbides and their stronger bond with the matrix in comparison with carbides of the Cr23C6 type or isolated secondary tantalum carbides.
