The technological and mechanical properties of some tungsten alloys

Conclusions

  1. 1.

    Extruded, rolled and forged rods have been produced from the vacuum-melted tungsten alloys: W−0.5 Ti, W−10 Mo−0.5 Ti, and W−0.5 Ti−0.1 Zr. To obtain good-quality rods from these tungsten alloys, an extention >4 must be used in extrusion.

  2. 2.

    The introduction of 10% Mo into the W−0.5 Ti alloy raises its strength at temperatures up to 2000°C and also improves the macrostructure and quality of the ingot, while maintaining adequate technological ductility.

  3. 3.

    The addition of 0.1% Zr to the W−0.5 Ti alloy sharply raises its recrystallization temperature and strengthens the alloy at 1500–1700°C, though working the alloy becomes more difficult.
