| Abstract Scope |
Interfaces play a significant role in the mechanical properties of metals starting from the effect of grain boundaries over twin boundaries to phase boundaries of both structural and chemical nature. This is well established in classical alloying systems, but still leaves open questions in nanoscale materials when the volume fraction of interface affected volumes does become significant. On occasion, however, mechanical deformation itself leads to the formation of new interfaces. The contribution will illustrate these effects by both exploring interfaces in reactive multilayer system as well as 3D printed nanostructures. In the former case an experimental study on Ni-Al multilayers will be compared to a molecular dynamics model that allows for the exploration of both small scale deformation as well as impact loading. In the latter the voxel to voxel change in both microstructure and chemistry will also shed light on local mechanical properties. Both approaches will be critically compared. |
