Effect of crystallogeometric states on the development of macrobands and deformation inhomogeneity in [111] nickel single crystals

The deformation relief in fee single crystals with a [111]-oriented compression axis at a strain of 0.05-0.15 was studied by optical and scanning electron microscopy. The effect of the alignment accuracy of crystallographic orientations of the compression axis and lateral faces on the development of deformation macrobands and folds was investigated by the example of nickel. The deformation inhomogeneity and the factors responsible for strain localization are determined by the grid method.
