Abstract: The thermal fatigue environment of gas turbine engine airfoils is severe and is often a life-limiting mode of failure. Alloy and coating system evaluation and accurate service life predictions ...

Abstract: An understanding of thermal mechanical fatigue (TMF) crack propagation is fundamental to the application of fracture mechanics to gas turbine components. Typical operating conditions for a cooled ...

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 ...
