| Abstract Scope |
Grain boundaries play a key role in determining the mechanical properties of polycrystalline materials, yet our understanding of grain boundary structure is incomplete. Most grain boundaries in real materials are random boundaries; yet the most commonly used grain boundary structural descriptors – the CSL and structural unit models – are ill suited to the description of random boundaries. In this work, we propose an alternative structural descriptor using an interstitial polyhedral model. This work presents several boundaries in FCC materials observed at atomic resolution with HRTEM and applies the interstitial polyhedral model to the interpretation of their structure. |
