| Abstract: | The paper Introduces fracture appearance transition character of turbine high and middle pressure rotor made metal material. It analyses the influence about fracture appearance transition temperature of rotor metal material to impact toughness and puts forward the demand to turbine star-up and over-speed experimentation aimed at extending turbine rotor life-span. |
