Description
Summary:Using the methods of electron backscatter diffraction, electron microscopy and X-ray diffraction analysis, it is demonstrated that irradiation of the surface of a submicrocrystalline molybdenum specimen with a pulsed electron beam in a non-melt regime results in the formation of a gradient structure in its bulk. The irradiation temperature is shown to affect the density of defects, the value of stress, and the distributions of grainboundary misorientations in the surface and bulk of the submicrocrystalline molybdenum specimens. Keywords: submicrocrystalline structure, distribution of grain-boundary misorientations, molybdenum, electron beam.
