摘要
文章介绍了超超临界汽轮机转子用9%-12%Cr耐热钢的发展历程,重点阐述了其基体组织与强化相的研究进展,并探讨了含B的 9%-12%Cr转子用中存在的问题,展望了超超临界机组汽轮机转子用耐热钢中的发展趋势.
Abstract
In the present work,the development and research on 9%-12%Cr martensitic heat-resistant steels have been review.Specifically,the focus was primarily placed on the microstructure and precipitates.The problems existing in the 9%-12%Cr marten-sitic heat-resistant steels containing B are discussed,and the development This article introduced the development and main method of strengthening of 9%-12%Cr steel used for Ultra-Supercritical fossil power plant steam turbine rotor.The improvement of rotor trend of heat-resistant steel used for ultra-supercritical steam turbine rotor is forecasted.
