Title Physically based plasticity model coupled with precipitate model for IN718
Author(s) Fisk, Martin ; Lindgren, Lars-Erik

English abstract
This talk describes the nucleation, growth and coarsening of γ′′ precipitates in Inconel 718 (IN718) during heat treatments. The model can be used in thermo-mechanical simulations of repair welding followed by heat treatment to predict residual stresses and final microstructure in aeroengine components. The interactions between precipitates and dislocations are included in a dislocation density based material model.
