Влияние горячей прокатки и обработки на твердый раствор на микроструктуру и механические свойства дуплексной нержавеющей стали 0Cr21Ni5Ti-2B с высоким содержанием бора

Ван Хуэй, Ван Тао

Аннотация


Разработана и изготовлена дуплексная нержавеющая сталь 0Cr21Ni5Ti-2B с содержанием бора 2 % (масс.). Определены фазовый состав стали, морфология и распределение боридов в различных состояниях: литом, после обработки на твердый раствор, горячей прокатки, горячей прокатки с последующей обработкой на твердый раствор. Исследовано влияние фазового состава и характеристик боридов на механические свойства стали.
