Conclusions

  1. 1.

    The surface of primary solidification of tungsten in the nickel-copper-tungsten system has been determined.

  2. 2.

    It is shown that raising the copper content of a copper-nickel melt sharply decreases the solubility of tungsten in the melt, particularly at low nickel contents.

  3. 3.

    Equations have been derived expressing the dependence of the solubility of tungsten on the composition of the melt and temperature.

  4. 4.

    An assessment is made of the solubility of tungsten in pure copper in the temperature range 1300–1550°C.
