Аннотация
На основе электрического взрыва проводников разработан метод высокоскоростной деформации материалов для исследований динамической прочности при ударных нагрузках микросекундной и субмикросекундной длительности. Проведены экспериментальные исследования динамических характеристик объемного металлического стекла на основе титана и циркония при ударных нагрузках субмикросекундной длительности (~0.5–0.7 мкс) в диапазоне давления до 12 ГПа. Для этих аморфных сплавов получены значения предела упругости Гюгонио и предела прочности на растрескивание. Определены параметры ударной адиабаты Гюгонио в пространстве Ush – up. В результате анализа микроструктуры сохраненных образцов выявлены области рекристаллизации.
