Nanocrystalline metals often exhibit high strength yet suffer from poor ductility. Here, the authors employ grain boundary engineering to overcome this problem by introducing amorphous intergranular films, which enables superior mechanical properties

Nanocrystalline Al-Mg alloys are used to isolate the effect of grain boundary doping on the strength of nanostructured metals. Mg is added during mechanical milling, followed by low homologous temperature annealing treatments to induce segregation wi

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 {\deg}C. Annealing drove Zr segregation to the grain boundaries, which led to the formation

We have fabricated single carbon nanowires (CNWs) suspended between carbon MEMS (CMEMS) structures with good Ohmic contacts employing photolithography, electrospinning and pyrolysis of SU8. By applying a current between the underlying CMEMS electrode

The control of interfaces in engineered nanostructured materials has met limited success compared with that which has evolved in natural materials, where hierarchical structures with distinct interfacial states are often found. Such interface control
Nanocrystalline materials are defined by their fine grain size, but details of the grain boundary character distribution should also be important. Grain boundary character distributions are reported for ball milled, sputter deposited, and electrodepo

Microcompression testing is used to probe the uniaxial stress-strain response of a nanocrystalline alloy, with an emphasis on exploring how grain size and grain boundary relaxation state impact the complete flow curve and failure behavior. The yield
