Nanomaterials are advanced materials exhibiting unique mechanical, chemical and physical properties due to their structural constituents having size less than 100 nm. Such materials are suitable for using in wide field of possible applications e.g. special structural applications, catalysis, biomedicine or electronics. There are many methods how to produce nanocrystalline materials or nanoparticles including vapor, liquid and solid processing routes. In this work, ultra-high-strength nanocrystalline silver was prepared by combination of selective leaching and subsequent consolidation by spark plasma sintering. Conventional cast silver was used as reference materials.

Keywords: nanocrystalline materials, silver, selective leaching, spark plasma sintering, mechanical properties
