Abstract Scope |
A coupling of Finite Element Method (FEM) and Kinetic Monte Carlo (KMC) models was devised in order to model the deformation, recrystallization, and grain growth response to the shear loading and annealing of Al-Si alloys. The coupling was demonstrated through comparison to data in the literature, and then applied to simulate the recrystallization of pure Al, Al-1Si, and Al-4Si between temperatures of 200 ºC and 400 ºC. Loading conditions of uniform shear and tribometric shear were considered. Experimental observation of recrystallization under tribometric loading conditions further validated the fidelity of our model predictions. This allowed us to predict the recrystallization nucleation behavior, recrystallization kinetics, and recrystallized grain structure of the deformed material as a function of temperature, loading, and Si composition. We propose this powerful capability is invaluable for modeling microstructural evolution in shear processing. |
