Creep of niobium alloy with solid solution reinforcement
- 24 Downloads
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.
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).
