Popis: The regularities of dislocation accumulation at forming dislocation structure of deformed martensitic steel are established on the base of electron microscopy. The factors determining an intensity of dislo- cation accumulation are revealed. Scalar dislocation density is divided into two components: density of geometrically necessary dislocations and density of statistically stored dislocations. The specifi c attention is given to geometrically necessary dislocations. Their accumulation in different substructure formations of the deformed steel is revealed. Critical grain sizes, when regularities of dislocation accumulation are changed, are determined
