Abstract
The results of a three-dimensional atom probe (3DAP) analysis, on a subnano meter scale, of a ceramic/metal heterophase interface, MgO/Cu, are presente d. Segregation of Ag, from the Cu (Ag) matrix, at MgO/Cu interfaces is inve stigated and the Gibbsian interfacial excess of silver is determined; the r ange is 2.33 x 10(18) to 5.81 x 10(18) m(-2). Also, silver segregation at t he same MgO/Cu interfaces is analyzed employing a new approach that utilize s a proximity histogram or proxigram.
