Conclusions

  1. 1.

    The addition of palladium to rhenium activates the sintering process of the latter. The optimum palladium content in our work was 0.2–0.4 wt.%.

     
  2. 2.

    The density of Re+ Pd specimens increases with rise in sintering temperature up to 2000°C.

     
  3. 3.

    After sintering at 1900–2000°C, specimens with a relative density of up to 92% of theoretical can be obtained from standard VTUR-6-4-63 rhenium powder activated with palladium, whereas specimens prepared from pure rhenium of the same batch have a density of the order of 80%.

     
  4. 4.

    It will be necessary to investigate the mechanism by which palladium influences the sintering process of rhenium powder.
