| Abstract Scope |
Phase-field modeling has proven its utility in predicting microstructure evolution for a variety of material systems. In this talk, recent applications of PRISMS-PF, an open-source, high-performance software framework, will be presented. First, an overview of PRISMS-PF, including recently implemented capabilities, will be discussed. Then, the talk will focus on its application to the simulation of the evolution of polycrystalline microstructures when stored energy in dislocations provides an additional driving force for grain growth. The model is employed to simulate the cyclic heat treatment of a Cu-Al-Mn-based alloy, in which the formation and dissolution of second-phase precipitates generate dislocations that contribute to the stored energy. The inhomogeneity in the dislocation density (and thus the stored energy) leads to complex grain morphologies, and the preferential formation of precipitates on grain boundaries provides large grains with an additional advantage for growth. Recent results on recrystallization and twinning will also be briefly discussed. |
