Влияние температуры старения на механические свойства при растяжении пластины из алюминиевого сплава 2219-T87
Аннотация
Исследовано влияние температуры и продолжительности искусственного старения на характеристики прочности и пластичности алюминиевого сплава 2219-T87 при статических испытаниях на растяжение пластины толщиной 6 мм. Установлено, что предел прочности сплава после старения снижается, а предел текучести значительно увеличивается в результате процесса дисперсионного твердения. При этом повышение температуры искусственного старения способствует более значительным изменениям прочностных характеристик сплава и снижению его пластичности, чем увеличение времени выдержки. Показано, что для достижения оптимального соотношения механических характеристик сплава 2219-T87 в каждом конкретном случае необходим индивидуальный подход к назначению режима искусственного старения.
