英文摘要：

The developmental progression of the material for the combined rotor of the steam turbine manufactured at home and broad was summarized. The effects of chemical composition and manufacturing technics on the steel of combined rotor were analyzed. And the comparison was done among six kinds of the rotor＇s material. It is pointed out that the service performance and manufacturing technology of the combined rotor of the steam turbine are now facing new challenge. More advanced technologies of smelting, ingot casting, forging and heat treatment will be applied to optimizing the material of the combined rotor. Besides, indepth research on the evolvement patterns of the rotor＇s material in service over a long period of time was developed.
