Abstract Scope |
Grain Boundaries (GBs) determine many of the properties of materials such as their strength, creep deformation, fatigue, and corrosion. Understanding the kinetics of grain boundaries is crucial to understanding material properties. In this study, we investigate the kinetics of Cu Sigma 5 (210) and Al Sigma 5 (210) GBs that are created by Molecular Dynamics Simulations. Then their potential energy landscapes are probed by Activation-Relaxation Technique, composing the data of kinetic transition events. The potential energy landscapes of the two materials with identical orientation, but chemical distinction, GBs are compared, specifically focusing on the chemical effect on modulating the activation energetics of GB kinetic processes. |
