摘要：

The phase composition and defect substructure of the pearlite steel (0.65%C, <1%Mn) layers with liquid and solid phase transformation subjected to pulse low-energy high-current electron beam processing have been investigated by means of transmission electron microscopy. The electron beam effect is expressed in the defect substructure change of the ferrite interlayers and in the amplitude increase of the far acting stress fields in the zone of thermal action. Different stages of polymorphous alpha ->gamma ->alpha transformation have been analyzed in a solid-phase transformation zone. The reasons for the formation of two-dimensional classes of alpha-phase grains with varying matrensite phase morphology in the liquid phase transformation zone are discussed.
