The glide of dislocations in a (441)-oriented Nb single crystal irradiated at 325 K with 5.5 x 10/sup 21/ neutrons/m/sup 2/ (E > 0.1 MeV) is shown for increasing time of tensile elongation (2 x 10/sup -4/ mm/s) in the High Voltage Electron Microscope at Argonne National Laboratory. The dimensions of the tensile specimen in the guage length were approximately 2 mm x 0.5 mm x 0.0001 mm. An electron energy of 900 keV was used during the simultaneous deformation and TEM observation.
