EVOLUTION OF THE STRUCTURE OF TIN BRONZE AND COPPER AFTER DYNAMIC COMPRESSION BY THE KOLSKY METHOD USING A SPLIT HOPKINSON PRESSURE BAR
DOI: 10.17804/2410-9908.2019.3.041-051 The effect of high-speed dynamic compression on the structure and mechanical properties of low-alloyed tin bronze in different initial states (coarse-grained, with additional annealing, and cast, obtained by spun casting) and commercially pure copper of the M1 standard is investigated. The results obtained show that the dynamic compression of tin bronze samples in the coarse-grained initial state causes intensive twinning starting from a strain rate of 2.6·103·s-1. At relatively low deformation rates, the dynamic compression of samples in the initial cast state promotes an increase in their strength characteristics, whereas, with a further strain rate increase, the development of relaxation processes is observed. However, additional homogenization annealing decreases the probability of relaxation processes under loading, which results in the highest possible mechanical characteristics. The studies of the M1 commercially pure copper have shown that variations in the deformation rate much less affect the properties than in case of bronze, and their values are lower due to relaxation processes both under loading and after deformation.

ЭВОЛЮЦИЯ СТРУКТУРЫ ОЛОВЯНИСТОЙ БРОНЗЫ И МЕДИ ПОСЛЕ ДИНАМИЧЕСКОГО СЖАТИЯ ПО МЕТОДУ КОЛЬСКОГО С ИСПОЛЬЗОВАНИЕМ РАЗРЕЗНОГО СТЕРЖНЯ ГОПКИНСОНА
Исследовано влияние высокоскоростного динамического сжатия на структуру и механические свойства низколегированной оловянистой бронзы в различном исходном состоянии (крупнокристаллическое, с дополнительным отжигом, и литое, полученное посредством центробежного литья) и меди технической чистоты стандарта М1. Полученные результаты показывают, что динамическое сжатие образцов оловянистой бронзы в крупнокристаллическом исходном состоянии приводит, начиная со скорости деформирования 2,6·103·c–1, к интенсивному развитию двойникования. В то же время при относительно небольших скоростях деформации динамическое сжатие образцов в исходном литом состоянии способствует повышению прочностных характеристик, а при дальнейшем повышении скорости деформации – к развитию релаксационных процессов. Однако дополнительный гомогенизирующий отжиг снижает вероятность протекания релаксационных процессов при нагружении, чем способствует получению максимально возможных механических характеристик. Испытания технически чистой меди М1 показали, что изменение скорости деформации значительно слабее влияет на свойства, чем в случае бронзы, и их значения ниже вследствие протекания релаксационных процессов как во время нагружения, так и после деформирования.
