Abstract
The plastic deformation of α-uranium single crystals was studied for various crystallographic orientations and temperatures. Explanations are given for the form of the strain curves in terms of the principal systems of plastic deformation. The single crystals were irradiated by neutrons in a reactor at temperatures up to 100°C with integral fluxes up to 5.5·1017 neutrons/cm2 and a flux of 4·1020 neutrons/cm2. The irradiation increased the critical shearing stress by factors of 3 to 5 for slip in the (010) plane and reduced the relative elongation and the region of “easy slip.” On annealing single crystals irradiated by fluxes up to 5.5·1017 neutrons/cm2 the mechanical characteristics were restored.
