Abstract:

An algorithm is developed that automates the application of the energy conserving orientational ECO force bicrystal grain boundaries. This will allow for simpler and more rapid calculations of grain boundary mobility values at varying orientations and temperatures. Additionally, the ECO driving force is expanded from its original implementation for only face-centered cubic crystals to body-centered cubic structures.
