The results of studies of the characteristics of the fine structure of a bimetal made of stainless steel 50Kh15M2F and carbon steel 20 after explosion welding and subsequent heat treatment in the joint zone are presented. It was found that normalization at temperatures above 900 ° C leads to a martensitic transformation in steel 50Cr15Мo2V, which is accompanied by an increase in hardness and the development of a fine structure: an increase in the level of elastic deformation of the crystal lattice and fragmentation of coherent scattering regions.
