Приведены данные о новом процессе достижения большой степени пластической деформации реверсивным выдавливанием в объемных заготовках с целью формирования мелкозернистой структуры. Разработан алгоритм этапов нагружения заготовки, обеспечивающий равномерное накопление степени деформации по ее объему. Приведены данные о кинематике течения металла, полученной путем моделирования процесса реверсивного выдавливания в Deform. Новая технология апробирована экспериментально с использованием меди М1. Проведено исследование микроструктуры после достижения степени деформации 5,5–6. Показана возможность получения объемной заготовки с величиной зерна 5–8 мкм.
