| Abstract: | This paper analyzes the mechanism of the temper embrittlement which happens in long-term used steam turbine rotor steel, points out the nondestructive inspecting method's application and problems for rotor steel, and expoundes on the development of electrochemical polarization method and chemical corrosion method. At last the opinion that how to improve the chemical corrosion method's precision is put forward. |
