Metallic nanoglasses are amorphous materials with microstructural features analogous to nanocrystalline materials, which consist of glassy grains connected by glass-glass interfaces. They can be produced by cold-compaction of glassy nanospheres which are prepared by inert-gas condensation [1,2]. The interfaces are characterized by an excess volume , a lack of short range order , and a different composition than the glassy grains . Moreover, the volume fraction of the interfaces depends significantly on the processing route .
In this contribution, we present a detailed analysis of the interplay between the deformation behavior and the microstructure of metallic nanoglasses. We discuss the role of the volume fraction of the interfaces, segregation at the interfaces, and the grain interiors in the deformation behavior of metallic nanoglasses during uniaxial tensile tests.
