A simple theoretical treatment of conduction in solids shows that apparent electron transport numbers determined by different experimental techniques are not identical. The techniques considered for stabilized zirconia were oxygen-transfer measurements and emf measurements on galvanic cells having oxygen at two different activities DELETE ABSTRACT 18377. The early stage of plastic deformntion in polycrystalline niobium at room temperature was investigated using a strain sensitivity of 1 x 10/sup -6/. Variables studied include grain size, prestraining, and strain-aging. In the annealed or locked dislocation condition, the 1 x 10/sup -6/ yield stress is while this yield stress is only 3.2-3.6 kg/mm/sup 2/ for specimens in the prestrained or unlocked dislocation condition. Observations of slip lines and dislocation etch pits in the microstrain region of annealed specimens indicate that grain-to-grain deformation occurs readily before the upper yield-point stress is reached.
