DEFORMATION STRUCTURE OF HIGH-PURITY IRON AFTER EXPLOSIVE LOADING IN SPHERICAL SYSTEMS
DOI: 10.17804/2410-9908.2016.6.069-079 The deformation structure of high-purity iron after loading by spherically converging shock waves is studied by optical metallography, transmission electron microscopy, and microhardness measurements. It is revealed that high-rate plastic deformation of iron proceeds by slip. Shear bands and bands of strain localization along grain boundaries are formed in the course of loading. A mixed structure consisting of dislocation cells and bands is observed at the microlevel. Under realized loading conditions, high-rate plastic deformation of iron proceeds in the ε-phase; therefore twins are not formed. The deformation structure of high-purity iron is compared with the structure of Armco iron formed after similar loading conditions. The found difference is explained by different mobility of dislocations.

ДЕФОРМАЦИОННАЯ СТРУКТУРА ВЫСОКОЧИСТОГО ЖЕЛЕЗА ПОСЛЕ ВЗРЫВНОГО НАГРУЖЕНИЯ В СФЕРИЧЕСКИХ СИСТЕМАХ
Методами металлографии, просвечивающей электронной микроскопии, а также измерением микротвердости изучена деформационная структура железа высокой чистоты после нагружения сферически сходящимися ударными волнами. Обнаружено, что высокоскоростная пластическая деформация железа осуществляется скольжением. В процессе нагружения происходит локализация деформации, приводящая к образованию полос сдвига, а в глубоких слоях шарового образца ‒ дополнительно полос локализации деформации по границам зерен. На микроуровне формируется смешанная структура, состоящая из ячеистой и полосовой структуры. При реализованных режимах нагружения высокоскоростная пластическая деформация протекает в ε-фазе, поэтому двойники не образуются. Проведено сравнение деформационной структуры высокочистого железа со структурой армко-железа, формирующейся после аналогичных условий нагружения.
