ABSTRACT The crack propagation behavior of conventionally cast and wrought INCONEL 718 has been assessed to determine the dominant advancement mechanisms under different loading regimes. Long crack fatigue testing was carried out under constant load (CL) and overload (OL) scenarios. Under CL, low stress intensity ranges (ΔK) produced a faceted fracture
