Выявлены факторы, определяющие интенсивность накопления дислокаций. Скалярная плотность дислокаций разделена на две компоненты: плотность геометрически необходимых и плот-ность статистически запасенных дислокаций. Особое внимание уделено геометрически необходимым дислокациям. Установлено их накопление с деформацией в различных субструктурных образованиях стали. Выделены критические размеры зерен, при которых изменяются закономерности накопления дислокаций.</p></abstract><trans-abstract xml:lang="en"><p>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.
