Fatigue crack initiation in nickel-based superalloys studied by microstructure-based FE modeling and scanning electron microscopy
In this work stage I crack initiation in polycrystalline nickel-based superalloys is investigated by analyzing anisotropic mechanical properties, local stress concentrations and plastic deformation on the microstructural length scale. The grain structure in the gauge section of fatigue specimens was...
