Computer simulation of phase transformation and plastic deformation in IN718 superalloy: Microstructural evolution during precipitation

Microstructural evolution during co-precipitation of γ′, γ″ and δ phases from a supersaturated γ matrix during aging of superalloy Inconel 718 (IN718) is investigated by computer simulation using the phase-field method. The precipitation model is quantitative, using as model inputs ab initio calcula...
