Аннотация

Работа посвящена исследованию особенностей выделения {111}α пластин Ω-фазы в Al–Cu–Mg сплаве с отношением Cu/Mg > 10 и низким содержанием Si. Впервые было установлено, что в отличие от Al–Cu–Mg-сплавов с добавлением Ag, в исследованном сплаве выделение наноразмерных пластин с габитусной плоскостью {111}α происходит по гетерогенному механизму, а именно вдоль малоугловых границ, линий дислокаций и на межфазной границе раздела θ′-фаза/Al-матрица.

Ключевые слова: фазовые превращения, упрочняющие частицы, старение, термоупрочняемый сплав, гетерогенное выделение
