Radial streaking in electron diffraction patterns from cold-worked metal foils

摘要: Abstract Electron diffraction patterns from thin foils of heavily deformed chromium and aluminium exhibited noticeable elongation the spots in a radial direction on each ring. The increased with area specimen irradiated by beam. For given beam size streaking decreased increasing recovery structure was absent fully annealed specimens. Several possible interpretations have been examined, but none is able to account satisfactorily for all effects observed.
