摘要：

The advantages of supercritical carbon dioxide Brayton cycle were analyzed based on the power system operation. The development of supercritical carbon dioxide Brayton cycle in fossil power, nuclear power and gas turbine power plants were reviewed. Candidate alloys used for the key hot components of the plants under supercritical carbon dioxide environment should have excellent corrosion resistance and mechanical properties. Therefore, the corrosion behavior of ferritic steels, austenitic steels and nickel based superalloys at different temperatures and pressures for supercritical carbon dioxide were investigated. The creep rupture life of several candidate materials at 650℃ was presented. Furthermore, some suggestions for supercritical carbon dioxide Brayton cycle were proposed from the aspects of material requirement. © 2016 Chin. Soc. for Elec. Eng.
