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…

Amorphous complexions enable a new region of high temperature stability in nanocrystalline Ni-W
Jennifer D. Schuler, Olivia K. Donaldson, Timothy J. Rupert
Solute segregation is used to limit grain growth in nanocrystalline metals, but this stabilization often breaks down at high temperatures. Amorphous intergranular films can form in…
