    Abstract

    Obtaining metallic materials with a grain size of tenths and hundredths of a micrometer (submicro and nanocrystals) with desired physicochemical properties is an important problem of modern materials science [1]. To date, several attempts have been made to refine the grain size by deformation at liquid nitrogen temperature [2–4], and most of this work was carried out on highly plastic copper. It seems relevant to a detailed study of the microstructure after cryogenic deformation, as well as the mechanisms of its formation. This work was aimed at a thorough certification of the microstructure of copper subjected to low-temperature deformation. For the certification of the microstructure, a relatively new method of automatic analysis of backscattered electron diffraction patterns (EBSD) was used.
