Mechanism-based modeling of anisotropic coalescence in superalloys
A new anisotropic criterion has been incorporated into a lattice model to predict rafting phenomena in nickel-base superalloys. The new criterion overcomes the limitations of earlier approaches, improves the prediction maps and is simple enough to be incorporated into a purely Monte Carlo algorithm which provides the evolution of a two-dimensional anisotropic lattice model associated with the superalloy. The results seem to reproduce the observed rafting behaviour even more accurately than a combined Monte Carlo-finite element approach, yet demand a much shorter computation time.
