摘要：
The mechanism of the formation of a fragmented structure has been studied using the EBSD analysis on the example of the microstructure of the zone of the welding joint obtained by explosive welding of copper sheets. The process of the structure formation included, besides the formation of boundaries of deformation origin, also deformation twinning and dynamic recrystallization. A method of a computer analysis of the distribution of interfragment misorientations, which makes it possible to determine the partial contributions of different mechanisms of fragmentation and to estimate the parameters of the distribution, is suggested. Based on the analysis performed, it is recommended to select metals inclined to deformation twinning to obtain ultrafine-grained materials.
