概要 （英文）

A STEAM TURBINE ROTOR CAN BE MENTIONED AS ONE OF THE MOST IMPORTANT COMPONENTS FOR SECURING THE RELIABILITY OF NUCLEAR AND THERMAL POWER PLANTS,SINCE IT IS A LARGE BODY ROTATING AT HIGH SPEED. THE RELIABILITY DEPENDS ON ACCURATE EVALUATION OF LOW-CYCLE FATIGUE LIFE CONTROLLED BY CRACK INITIATION AND PROPAGATION UNDER CREEP-FATIGUE INTERACTION. IN THIS REPORT,THE BEHAVIOR OF ELEVATED TEMPERATURE LOW-CYCLE FATIGUE CRACK INITIATION AND PROPAGATION IN STEAM TURBINE ROTOR STEELS IS DISCUSSED,BASED ON THE TEST RESULTS OF SMOOTH AND NOTCHED SPECIMENS.
