Аннотация


Исследована возможность повышения ударной вязкости среднемарганцевой TRIP-стали Fe - 0,2 % C - 6 % Mn - 3 % Al за счет применения новой термической обработки, включающей закалку из межкритического интервала температур и последующий отпуск. Проведены электронно-микроскопические и рентгеноструктурные исследования стали после термической обработки. Определен режим закалки, при использовании которого достигается наиболее высокая ударная вязкость.
