Segregation competition and complexion coexistence within a polycrystalline grain boundary network
P Garg, Z Pan, V Turlo +1
Interfacial segregation can stabilize grain structures and even lead to grain boundary complexion transitions. However, understanding of the complexity of such phenomena in polycry…
Mechanisms of near-surface structural evolution in nanocrystalline materials during sliding contact
Zhiliang Pan, Timothy J. Rupert
The wear-driven structural evolution of nanocrystalline Cu was simulated with molecular dynamics under constant normal loads, followed by a quantitative analysis. While the microst…
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,…
Amorphous intergranular films as toughening structural features
Zhiliang Pan, Timothy J. Rupert
The ability of amorphous intergranular films to mitigate damage formation at grain boundaries is studied with molecular dynamics simulations. We find that such films can alter both…
Damage nucleation from repeated dislocation absorption at a grain boundary
Zhiliang Pan, Timothy J. Rupert
Damage nucleation from repeated dislocation absorption at a grain boundary is simulated with molecular dynamics. At the grain boundary-dislocation intersection site, atomic shuffli…
