Аннотация


Исследованы механические свойства порошковой стали, содержащей 0,06 % C, 22 % Cr, 13 % Ni, 5 % Mn, 2,0 % Mo (UNS S20910), полученной механическим легированием с последующим отжигом. Определены изменения структуры в процессе механического легирования и отжига методами рентгеновской дифракции, световой и электронной сканирующей микроскопии с приставкой для энергодисперсионного анализа. Определены режимы прессования и спекания для получения оптимальных механических свойств стали.

Ключевые слова
