摘要
介绍汽轮机高中压转子金属材料的脆性转变特性。分析转子金属材料脆性转变温度(FATT)对冲击韧性的影响,提出为延长汽轮机转子寿命对汽轮机启动和超速试验的要求。
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.
