摘要：

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 Sigma 13 GB with an additional twist component. The reliability and precision of this new approach is analyzed and the limitations are discussed. (C) 2016 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
