Ультрамелкозернистые Al – Mg2Si-сплавы с добавками переходных металлов и улучшенными механическими свойствами
Аннотация
Исследовано влияние комбинированной обработки методом ротационной ковки при комнатной температуре с последующим равноканальным угловым прессованием при 150 °C и старением на структуру, фазовые превращения и прочностные характеристики Al – Mg2Si-сплавов, легированных Sc или добавками (Sc + Zr) и (Sc + Hf ). На основании полученных результатов исследований рекомендованы режимы старения сплавов в исходном состоянии и при комбинированной обработке, обеспечивающие повышение как их прочности, так и пластичности. Наилучший комплекс механических характеристик получен у сплава Al – Mg2Si с добавкой (Sc + Hf ).
