Cyclic Behavior of Turbine Disk Alloys at 650°C
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Five gas turbine disk alloys representing a range of strengths and processing methods were tested for resistance to both cyclic crack initiation and propagation at 650° C using a 0.33 Hz ...
Gas Turbine Engine Disk Retirement-for-Cause: An Application of Fracture Mechanics and NDE
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Historically, gas turbine engine disks are retired when they accrue an analytically determined lifetime where the first fatigue crack per 1000 disks could be expected. By definition then, 99.9 ...
