Аннотация


Исследована аустенитная сталь AFA, легированная 4 % Al, в состоянии поставки и после отжига при 1050 и 1230° C. Определен химический состав стали, проведен микроструктурный анализ, изучена морфология вторичных фаз с использованием методов сканирующей электронной микроскопии и дифракционного анализа. Получены кривые высокотемпературной ползучести. Проанализированы изменения свойств стали после испытаний на ползучесть. Показано положительное влияние отжига на сопротивление ползучести стали AFA. Установлено, что после отжига при 1230° C сталь имеет лучшие характеристики высокотемпературной ползучести: установившаяся скорость ползучести равна 1,61 · 10-6 с-1, а энергия активации 608,2 кДж/моль.

Ключевые слова
