Исследование микроструктуры и механических свойств гибридных композитов A713 – TiB2 – графен, полученных методом литья с перемешиванием
Аннотация
Исследованы микроструктура и механические свойства алюминиевых композитов на основе матричного сплава A713, армированного частицами TiB2 и графена. Композиты изготовлены с использованием технологии литья с перемешиванием. Содержание армирующих частиц графена в композитах сохранялось постоянным — 0,5 % (масс.), количество частиц TiB2 варьировалось — 2, 4 и 6 % (масс.). Проведен микроструктурный анализ композитов методами световой и электронной микроскопии, а также рентгеновской дифракции. Определены механические свойства методами испытаний на растяжение и измерения твердости. Для оценки характера разрушения образцов при растяжении выполнен анализ поверхности излома с использованием СЭМ.
