Conclusions

  1. 1.

    Alloying of tungsten and W−C alloys with zireonium, niobium, and tantalum increases the short-term and also the long-term strength. The strength is increased most by small additions of the alloying element (up to 0.1 at. %). In effectiveness of hardening at temperatures ≤0.6Tm the elements investigated are arranged in the following order: Zr, Nb, Ta.

  2. 2.

    At temperatures ≥0.6Tm separate and combined alloying of tungsten with carbon and substitutional elements of groups IV and V does not improve the heat resistance.

  3. 3.

    Alloying elements raise the ductile-brittle transition temperature Tx of tungsten and W−C alloys. The increase of Tx is highest with the addition of zirconium.
