Percolation of Ion-Irradiation-Induced Disorder in Complex Oxide Interfaces
Bethany Matthews, Michel Sassi, Christopher M. Barr +5
Mastery of order-disorder processes in highly non-equilibrium nanostructured oxides has significant implications for the development of emerging energy technologies. However, we ar…
Amorphous intergranular films mitigate radiation damage in nanocrystalline Cu-Zr
Jennifer D. Schuler, Charlette M. Grigorian, Christopher M. Barr +3
Nanocrystalline metals are promising radiation tolerant materials due to their large interfacial volume fraction, but irradiation-induced grain growth can eventually degrade any im…
Solid-state dewetting instability in thermally-stable nanocrystalline binary alloys
Jennifer D. Schuler, Guild Copeland, Khalid Hattar +2
Practical applications of nanocrystalline metallic thin films are often limited by instabilities. In addition to grain growth, the thin film itself can become unstable and collapse…
In situ high-cycle fatigue reveals the importance of grain boundary structure in nanocrystalline Cu-Zr
Jennifer D. Schuler, Christopher M. Barr, Nathan M. Heckman +4
Nanocrystalline metals typically have high fatigue strengths, but low resistance to crack propagation. Amorphous intergranular films are disordered grain boundary complexions that…
