Determination of local strains in a neighborhood of cracks in a welded seam of Ni-Cr-Fe according to the power Fourier spectrum of Kikuchi patterns
Journal Title: Фізика і хімія твердого тіла - Year 2018, Vol 19, Issue 4
Abstract
A discrete two-dimensional Fourier transform and the power Fourier spectrum are used for determination of average strains near cracks in a welded seam of Ni-Cr-Fe alloy. The alignment of Kikuchi images with the help of genetic algorithms and subtraction of white Gaussian noise made it possible to more fully take into account the influence of instrumental factors on the formation of electron backscatter diffraction patterns.
