摘要
超超临界电站能够有效提高化石燃料的利用率,缓解能源危机和环境压力。马氏体型耐热钢因其有良好的热物理性能和廉价的成本而广泛应用于电站锅炉中。650℃及以下的电站锅炉关键材料主要采用马氏体型耐热钢。介绍了世界各主要国家探索开发650℃马氏体耐热钢的主要科技项目,包括欧洲、美国和日本。从合金化角度介绍了马氏体耐热钢中主要元素的作用。介绍了当前研究650℃马氏体耐热钢的主要成果,分析了这些钢种的强化机制。
The ultra-supercritical power plants are accepted for high energy efficiency in the world. The ultra-supercritical technology will release pressure of energy crisis and environment problems. Because of its good thermal properties and cheap cost,martensite heat-resistant steel is widely used in power station boiler. The martensite creep-resistant steels were used as key materials for power plant applications with service temperatures not exceeding 650 ℃. The projects about these kind of materials were recommended in some main countries. The effects of various elements were analyzed based on alloying principle in creep-resistant steels. Some new creep-resistant steels designed for 650℃power plant applica-tions recently were discussed and the strengthening mechanism was analyzed.
