High temperature fatigue crack growth in powder processed nickel based superalloy U720Li

High temperature fatigue crack growth in powder processed nickel based superalloy U720Li

Fatigue crack propagation at elevated temperatures (650 and 725°C) has been studied in a powder processed high strength nickel based superalloy, U720Li, in air and vacuum environments, using trapezoidal loading waveforms. Constant load (increasing ΔK) tests were used to generate daldN-ΔK curves, whi...
