Microstructural aspects of fatigue in Ni-base superalloys [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015 Nickel-base superalloys are primarily used as components in jet engines and land-based turbines. While compositionally complex, they are microstructurally simple, consisting of small (50–1000 nm diameter), ordered, coherent Ni3(Al,Ti)-type L12or Ni3Nb-type DO22precipitates (calledγ′andγ′′, respectively) embedded in an FCC substitutional solid solution ...
