Ultrahigh strength and high electrical conductivity in copper
TL;DR: Pure copper samples with a high density of nanoscale growth twins are synthesized and show a tensile strength about 10 times higher than that of conventional coarse-grained copper, while retaining an electrical conductivity comparable to that of pure copper.

Revealing the Maximum Strength in Nanotwinned Copper
TL;DR: The maximum strength of nanotwinned copper samples with different twin thicknesses is investigated, finding that the strength increases with decreasing twin thickness, reaching a maximum at 15 nanometers, followed by a softening at smaller values that is accompanied by enhanced strain hardening and tensile ductility.

Deformation Twinning in Nanocrystalline Aluminum
TL;DR: Transmission electron microscope observations that provide evidence of deformation twinning in plastically deformed nanocrystalline aluminum underscore a transition from deformation mechanisms controlled by normal slip to those controlled by partial dislocation activity when grain size decreases to tens of nanometers, and they have implications for interpreting the unusual mechanical behavior of nanocrystaline materials.
