[Auszug] At about this strain rate the yield stress of niobium free of impurities is predicted2 to be ~ 2.5 kg mm2 and this is postulated to be the PeierlsNabarro force. Considering this model, the yield stress of this 'pure' niobium at 77 K should be ~ 50 kg mm2. Using a 'flash-annealing' technique the ...
