Conclusions

  1. 1.

    The effect has been investigated of porosities from 5 to 35% on the creep characteristics during the compression of niobium carbide testpieces over the temperature range 2250–3200 °K and over the stress range 1–5 kgf/mm2.

     
  2. 2.

    The test data agree satisfactorily with the analytical relation\(\hat \dot \varepsilon = \exp (5n/\Pi )\), obtained on the basis of a model of a porous body, taking into account the complex stress distribution.
