Abstract
In this study, the mechanical performance and deformation behavior of various nano-twinned Ag foils were evaluated under two deformation modes. It was generally observed that the addition of nanotwins led to an enhanced strength, but the overall plastic flow and ductility decreased. Using a bimodal distribution of nanotwinned and non-nanotwinned grains was shown to be a possible route for overcoming this limitation. Specifically, some strengthening was observed which can be attributed to the nanotwinned grains, while the ductility was attributed to the contribution from non-nanotwinned grains. The overall deformation behavior is presented and discussed in terms of the nanotwin volume fraction.
Highlights
Nanotwinned (NT) metals have been the subject of many recent studies as they have shown the potential for achieving high strengths, comparable to nanocrystalline metals, while maintaining other desirable properties
Kulkarni and Asaro showed by molecular dynamics (MD) simulations that the deformation behavior and dislocation-twin boundary (TB) interactions in NT-Ag should be similar to NT-Cu.[3]
The effects of varying the volume fraction of NT grains in Ag foils are reported and the mechanical performance is examined under two different deformation modes
Summary
Nanotwinned (NT) metals have been the subject of many recent studies as they have shown the potential for achieving high strengths, comparable to nanocrystalline (nc) metals, while maintaining other desirable properties. The effects of varying the volume fraction of NT grains in Ag foils are reported and the mechanical performance is examined under two different deformation modes.
