The influence of rolling at a liquid-nitrogen temperature on the microstructure of commercially pure copper has been investigated by the methods of transmission electron microscopy (TEM) and automated analysis of electron backscatter diffraction (EBSD) patterns. It has been established that the process of the structure formation was sufficiently complex and included a geometric effect of deformation, recrystallization, twinning, and fragmentation. It is shown that upon deformation to 50% the structure evolution was controlled by the Taylor-Polanyi principle. However, it was established that at larger reductions the formation of grain structure was determined by the competition between the geometric effect of deformation and recrystallization. The contribution of twinning and fragmentation to the structure formation was insignificant in the entire interval of deformations investigated. The recrystallization, apparently, was caused by the warming up of the sample to room temperature after low-temperature rolling.
