Modelling the creep anisotropy of nickel-base superalloys with a composite model

Abstract
The creep anisotropy of nickel-base superalloys with a cubic γ' morphology is studied with a composite model. Creep curves and the internal stress distribution in the microstructure under [011] load are calculated with a Finite Element Procedure. Analytical considerations are made for arbitrary loading directions. γ' cubes (with their interfaces aligned parallel to {001} planes) under [001] load have a significant larger creep strength than under [011] or [111] load. Under [011] load the matrix deformation is mainly concentrated in the roof matrix channels.
