3DAP Analysis of Au Segregation at a CdO/Ag Metal/Ceramic Heterophase Interface (J. T. Sebastian).
Atomic reconstruction of an MgO ceramic precipitate in a Cu metal matrix (the matrix atoms are omitted for the sake of clarity). From J. Ruesing, J. T. Sebastian, O. C. Hellman, and D. N. Seidman, "Three-Dimensional Investigations of Ceramic/Metal Heterophase Interfaces by Atom-Probe Microscopy," Microscopy and Microanalysis, 6 445-451 (2000). Data collected using the 3DAP and rendered using Apex.
