| Abstract Scope |
An advanced phase field model that is capable of accounting for dislocation behavior on various slip planes in hexagonal close packed materials is used to quantify and compare equilibrium stacking fault widths, loop formation, and dislocation motion for multiple active slip modes in magnesium. Our phase field model is directly informed with density functional theory, which enables the model to consider slip-mode dependent energetics. As such, we anticipate that the intrinsic dislocation behavior, quantified using the phase field dislocation dynamics model, will be useful input informing larger-scale plasticity modeling of Mg and Mg alloys. |
