Using crystal plasticity, finite element analyses were carried out to model cyclic deformation for a low solvus high refractory (LSHR) nickel superalloy at elevated temperature. The implemented using representative volume (RVE), consisting of realistic microstructure obtained from SEM images the material. Monotonic, stress-relaxation and test data 725 °C used determine parameters fitting process their sensitivity RVE size random grain orientation. In combination with extended method (XFEM),...
ABSTRACT The complex geometrical configuration of shaped film cooling holes (FCHs) enhances the efficiency turbine blades, while stress concentration at FCH edge and manufacturing defects usually leads to high‐cycle fatigue (HCF) failure under service conditions. In this study, HCF tests 900°C were conducted on DD6 single‐crystal superalloy containing dustpan dovetail FCHs. effect FCHs strength was investigated, related mechanism analyzed using SEM, EDS, EBSD. results show that including...
Ni-based superalloys in turbine disc applications face increasing susceptibility to oxygen-assisted fatigue crack propagation due increased entry temperatures. The continued lack of understanding the interplay between factors operating during limits: (1) development lifing methodologies accurately predict performance alloys/components and (2) associated alloy developments. An underpinning requirement better understand role oxygen is characterise process diffusion localised stress/strain...
Abstract The strain localization and crack initiation behavior of a powder metallurgy (PM) nickel‐based superalloy FGH4098 under low cycle fatigue (LCF) loads at room temperature is investigated by combining scanning electron microscope (SEM)‐digital image correlation (DIC) characterization with crystal plasticity simulation. elastic anisotropy near annealing twin boundaries contributes to results in high propensity LCF failure. effect local microstructure on the {111} slip bands tortuous...
