Маэн Хансо, Чой Юнг, Ли Сьок-Джа

Аннотация


Представлена модель дисперсионного твердения сплава системы Al - Mg - Si за счет выделения нескольких фаз, образующихся при различных условиях старения. Определены диаметры частиц выделяющихся фаз и их относительное количество методом термодинамического моделирования. Характеристики выделившихся фаз были учтены в предложенной модели, что привело к более точному прогнозированию. Установлено ускорение выделения β- и β'-фаз при увеличении времени старения и ускорение роста их частиц с повышением температуры.

Ключевые слова


модель; дисперсионное твердение; старение; сплав системы Al - Mg - Si; model; precipitation hardening; aging; alloy of the Al - Mg - Si system
