Abstract
The flow stress of Nickel-based γ/γ′ superalloys containing up to 73 vol.% of Ni 3Al precipitates is calculated by dislocation dynamics simulations of a dislocation pair gliding on {111} planes, for temperatures up to 1000 K. It is calculated for different composition-related parameters (friction stress and APB energy), as well as for different microstructural parameters (channel width, precipitate volume fraction and the geometry of the intersection of the {111} glide plane with the precipitate). The emphasis is on the bowing-assisted cutting regime, which is the prevalent deformation mechanism observed in the simulations.
