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…
Materials selection rules for amorphous complexion formation in binary metallic alloys
Jennifer D. Schuler, Timothy J. Rupert
Complexions are phase-like interfacial features that can influence a wide variety of properties, but the ability to predict which material systems can sustain these features remain…
