Numerical Modeling of Microstructure Formation during Solidification and Heat Treatments of Ni-base superalloys

Abstract : Numerical models have been developed for the simulation of microstructure formation in Ni-base alloys. The first step consists of a calculation of the segregation of solutal species in the primary solidified g-phase and formation/dissolution of the interdendritic g'-phase. Finally, local compositions of solutal species are used to calculate the nucleation, growth and coarsening of g'-precipitates with a precipitation model.
