Влияние предварительного растяжения и режимов искусственного старения на микроструктуру и свойства Al - Li-сплава 2А97-Т3

Чжан Пэн, Чэнь Мин-Хэ

Аннотация


Исследовано влияние различных режимов старения и предварительного растяжения (3 %) на микроструктуру и механические свойства Al - Li-сплава 2А97-Т3 (1,31 % Li; 3,55 % Cu; 0,37 % Mg, остальное алюминий). Проведены растровая электронная микроскопия сплава в комбинации с энергодисперсионной спектроскопией, а также электронная микроскопия в обратно рассеянных электронах. Определен предел прочности при испытаниях на растяжение.
