A research team led by Brown University engineers has discovered a new mechanism that governs the peak strength of nanostructured metals. The team found that the deformation of nanotwinned metals is characterized by the motion of highly ordered, necklace-like patterns of crystal defects called dislocations. The finding, published in Nature, could lead to stronger and more ductile metals.
