Abstract
Method loading by spherical converging shock waves was applied to study the high-rate plastic deformation of a niobium single crystal. The structure of the recovered specimen was studied by X-ray diffraction analysis, optical, scanning, and transmission electron microscopy as well as by the measurement of microhardness along the radius in some radial directions. It is established that a niobium single crystal under such loading acquires polycrystalline structure and the high-rate plastic deformation of it occurs by slip and by formation of deformation vortices.
