Abstract
The phase composition and defect substructure formed in carbon steel subjected to a microsecond high-current e-beam have been studied by the thin-foil electron diffraction microscopy. It has been shown that the mechanism and the degree of globular cementite dissolution, phase composition and the morphology of the appearing structure depend on the distance from a melt spot and are determined by the temperature field gradient. As an electron beam approaches the "spot" (the increase in steel temperature), the evolution of the material volume containing cementite particles is accompanied by the formation of structures that alternate in a regular manner.
