| Summary: | Title screen The transmission electron microscopy (TEM) has been used to indicate the contribution of stress tensorcomponents to internal stresses in deformed polycrystalline austenitic steel. TEM images of steel deformation demonstrate bend extinction contours the parameters of which allow detecting the stress tensor components (bending and torsional stresses of a crystal lattice). The diagrams are constructed for the contribution of stress tensor components to internal stresses in grains having different types of bending. The regularities are obtained for the stress distribution due to bending-torsion of a crystal latticein the deformed face centered cubic crystal system. The experiment shows that the contribution of bending and torsion stress components to the internal stresses is different during the increase of deformation. The torsion stress component always grows with the increase of deformation, while the bending stress component either grows or lowers. The growth in the torsion stress component is typical for grains with compound bending. Режим доступа: по договору с организацией-держателем ресурса |
