Nanocrystalline Al-Mg with extreme strength due to grain boundary doping
Simon C. Pun, Wenbo Wang, Amirhossein Khalajhedayati +3
Nanocrystalline Al-Mg alloys are used to isolate the effect of grain boundary doping on the strength of nanostructured metals. Mg is added during mechanical milling, followed by lo…
Spatial variation of short-range order in amorphous intergranular complexions
Zhiliang Pan, Timothy J. Rupert
Amorphous materials lack long-range order but short-range order can still persist through the recurrence of similar local packing motifs. While the short-range order in bulk amorph…
Formation of ordered and disordered interfacial films in immiscible metal alloys
Zhiliang Pan, Timothy J. Rupert
Atomistic simulations are used to study segregation-induced intergranular film formation in Cu-Zr and Cu-Nb alloys. While Cu-Zr forms structurally disordered or amorphous films, or…
Plasticity-induced restructuring of a nanocrystalline grain boundary network
Jason F. Panzarino, Timothy J. Rupert
The grain boundary-mediated mechanisms that control plastic deformation of nanocrystalline metals should cause evolution of the grain boundary network, since they directly alter mi…
Effect of grain boundary character on segregation-induced structural transitions
Zhiliang Pan, Timothy J. Rupert
Segregation-induced structural transitions in metallic grain boundaries are studied with hybrid atomistic Monte Carlo/molecular dynamics simulations using Cu-Zr as a model system,…
