Effect of method of manufacture on the structure and lamination tendency of thoriated tungsten

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

  1. 1.

    To obtain fine and evenly distributed thoria particles, it is necessary to produce bars from finegrained powders.

  2. 2.

    To obtain the comparatively large grain that facilitates the working of tungsten, it is necessary to weld bars made of a fine-grained powder at a temperature of 2600±50°C.

  3. 3.

    Only bars of sufficiently high density (>18.0 g/cm3) and even ThO2 particle distribution should be subjected to plastic working.

  4. 4.

    After recrystailization annealing the size of the tungsten grains should be not larger than 5–8μ. All these factors decrease the lamination tendency of tungsten.
