The resulting microstructures have been studied as a function of annealing temperature by means of XRD and TEM in-situ. It is shown that IGC of the prealloy results in a duplex nanostructure, whereas MA and SPID lead to a metastable solid solution phase that decomposes to fine Ag and Cu on heating.enKornwachstumKugelmahlenmechanisches LegierenMikrogefügenanokristalliner WerkstoffPulvermetallurgiePulverpressenRöntgenbeugung620660671Influence of powder consolidation methods on the structural and thermal properties of a nanophase Cu-50wt%Ag alloyEinfluß der Pulverkompaktierungsmethode auf das Gefüge und die thermischen Eigenschaften einer nanokristallinen Cu-50gew%Ag Legierungjournal article
