As predicted from thermodynamic considerations, a grain boundary segregated monophase alloy is observed in the annealed mechanically alloyed state for low Ag content by using atom probe tomography. From the detected Ag solute grain boundary enrichment the segregation free enthalpy is estimated to range between -25 and -49 kJ mol^-1 following the McLean equation, in agreement with values reported for coarse-grained Cu–Ag. The extension of the alloying range is described by a two-domain thermodynamic model that considers the excess free volume in the grain boundaries and the strain in the strain interior on the basis of the universal equation of state at negative pressure. To access the grain boundary volumetric strain experimentally, a method based on a combination of density measurements and microscopical quantification of closed pore areas is presented. Moreover, we apply x-ray diffraction line broadening analysis to determine the local strain amplitude, which yields a root-mean-square microstrain of 0.3% for a grain size of 30 nm. It is shown that the grain boundary free volume represents the major origin for the global solubility enhancement in nanocrystalline Cu–Ag at 503 K.}}, author = {{Riedl, Thomas and Kirchner, A and Eymann, K and Shariq, A and Schlesiger, R and Schmitz, G and Ruhnow, M and Kieback, B}}, issn = {{0953-8984}}, journal = {{Journal of Physics: Condensed Matter}}, number = {{11}}, publisher = {{IOP Publishing}}, title = {{{Elemental distribution, solute solubility and defect free volume in nanocrystalline restricted-equilibrium Cu–Ag alloys}}}, doi = {{10.1088/0953-8984/25/11/115401}}, volume = {{25}}, year = {{2013}}, } @inproceedings{4113, author = {{Lindner, Jörg}}, location = {{Kusadasi (Turkey)}}, title = {{{Ion Interactions with Nanopatterned Surfaces}}}, year = {{2013}}, }
