High-temperature stability and grain boundary complexion formation in a nanocrystalline Cu-Zr alloy
Amirhossein Khalajhedayati, Timothy J. Rupert
Nanocrystalline Cu-3 at.% Zr powders with ~20 nm average grain size were created with mechanical alloying and their thermal stability was studied from 550-950 °C. Annealing drove Z…
Grain boundary character distributions in nanocrystalline metals produced by different processing routes
David B. Bober, Amirhossein Khalajhedayati, Mukul Kumar +1
Nanocrystalline materials are defined by their fine grain size, but details of the grain boundary character distribution should also be important. Grain boundary character distribu…
Disruption of Thermally-Stable Nanoscale Grain Structures by Strain Localization
Amirhossein Khalajhedayati, Timothy J. Rupert
Nanocrystalline metals with average grain sizes of only a few nanometers have recently been observed to fail through the formation of shear bands. Here, we investigate this phenome…
