| Abstract: | The key of the ultra-supercritical power generation development is the high temperature materials properties.In the present paper,the alloying and main properties of ferritic steels,austenitic steels and Ni-based alloys used for the ultra-supercritical power generation are discussed.It is indicated that the resistance to steam oxidation and fire-side corrosion becomes more important with the increase of the boiler parameters,which advances the development of new austenite steels and Ni based alloys.Moreover... |
