Abstract
A three-dimensional finite element (F.E.) model is used to estimate the mismatch stresses at a microscopic scale in γ - γ' single-crystal nickel-based superalloys. F.E. calculations point out the specificity of stress/strain distributions in these alloys, in particular the fact that internal stresses concentrate in the connected γ matrix. The analysis of stress/strain fields and elastic energy evolution as a function of precipitate morphology and volume fraction allows to explain some atypical precipitate shape changes such as splitting during precipitation treatments or raftening during high temperature creep tests.
