Amorphous complexions alter the tensile failure of nanocrystalline Cu-Zr alloys
Jenna L. Wardini, Charlette M. Grigorian, Timothy J. Rupert
Grain boundary-based mechanisms are known to control the plastic deformation and failure of nanocrystalline metals, with manipulation of the boundary structure a promising path for…
Multi-principal element grain boundaries: Stabilizing nanocrystalline grains with thick amorphous complexions
Charlette M. Grigorian, Timothy J. Rupert
Amorphous complexions have recently been demonstrated to simultaneously enhance the ductility and stability of certain nanocrystalline alloys. In this study, three quinary alloys (…
Critical cooling rates for amorphous-to-ordered complexion transitions in Cu-rich nanocrystalline alloys
Charlette M. Grigorian, Timothy J. Rupert
Amorphous complexions in nanocrystalline metals have the potential to improve mechanical properties and radiation tolerance, as well as resistance to grain growth. In this study, t…
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…
Thick amorphous complexion formation and extreme thermal stability in ternary nanocrystalline Cu-Zr-Hf alloys
Charlette M. Grigorian, Timothy J. Rupert
Building on the recent discovery of tough nanocrystalline Cu-Zr alloys with amorphous intergranular films, this paper investigates ternary nanocrystalline Cu-Zr-Hf alloys with a fo…
