Conclusions

  1. 1.

    The W-Re equilibrium diagram has been constructed [Figure 6].

  2. 2.

    Addition of Re to tungsten raised the temperature of incipient recrystallization of tungsten VCh wire by 200–400°C, depending on the rhenium content.

  3. 3.

    Rhenium improved the strength and ductility of tungsten in the 20–3000°C range.

  4. 4.

    W-Re wire developed a high strength and ductility after annealing at 1400–1950°C. An alloy with 20% Re annealed at 1400–1500°C had a strength of 180–190 kg/sq. mm and 18–20% elongation.

  5. 5.

    W-Re alloys were harder than plain W in the 20–1000°C range. At 800°C, the alloys with 10, 25 and 75% Re had a hardness of about 200 kg/sq. mm while an alloy of W with 2% Re had one of about 110 kg/sq. mm.

  6. 6.

    Alloying of tungsten with rhenium increased several-fold its resistivity at various temperatures.

  7. 7.

    W-Re alloys can be recommended for elements of electric vacuum devices such as cathodes, heaters, radio tube grids, etc. They are also suitable for thermocouples and electrical contacts.
