Conclusions

  1. 1.

    The creep of niobium alloys with solid-solution reinforcement in the temperature range 800–1600°C is controlled by the same mechanism: the transition of edge dislocations.

     
  2. 2.

    The use of Garofalo-Li coordinates (log [Sh(ασ)] − logɛstab) makes possible the extrapolation of the established creep rate to lower rates (to 0.00001% ·h−1).
