Abstract
Область использования: материаловедение и может найти применение при изготовлении и термической обработке канальных и твэльных труб из циркониевых сплавов. Сущность изобретения: изделия подвергают нагреву до 920 950°С со скоростью не менее 100°С/с, выдерживают при этих температурах в течение 10 15 с, охлаждают до комнатной температуры со скоростью 450 1200°С/с в интервале температур 920 500°С, после чего отжигают в течение 24 100 ч при 580 540°С соответственно. В результате такой обработки существенно улучшаются ползучесть и коррозионная стойкость за счет создания квазиизотропной мелкозернистой структуры. 4 табл. 2 ил.
