Forschungsartikel (Zeitschrift) | Peer reviewedZusammenfassung
A novel approach for quantitative measurements of grain boundary (GB) excess volume has been developed using correlative analytical transmission electron microscopy (TEM) and successfully demonstrated for several simulated symmetrical [100] tilt GB configurations as well as for the experimental case of an Al bicrystal containing a near Σ13GB with an additional twist component. The reliability and precision of this new approach is analyzed and the limitations are discussed.
