Presentation Title Sharp Phase-Field Modeling of γ" Microstructure Evolution in Ni-base Superalloys

On-Site Speaker (Planned) Felix Ulrich Schleifer
Abstract Scope The γ" phase contributes significantly to the superior high-temperature performance of Nb containing Nickel alloys such as IN718. This tetragonal phase precipitates coherently in an fcc solid solution matrix and forms plate-shaped particles. The precipitate shape is determined by the interplay between interfacial energy and elastic lattice distortion. We investigate the formation of such a microstructure using the novel sharp phase-field model and quantify the relation between the precipitate shape and ripening kinetics. We consider tetragonal anisotropy of interfacial energy and misfit strains in two and three dimensions at high volumetric phase fractions. Using the sharp phase-field approach and the theory of precipitate ripening we identify critical parameters for the prediction of γ/γ" microstructure evolution. Based on this extensive description of the microstructure formation we present large-scale simulations of γ/γ" microstructural evolution during heat-treatment and life-time of Ni-based superalloys.
