Deformation mechanisms, length scales and optimizing the mechanical properties of nanotwinned metals

Refinement of microstructural length scales and modification of interface character offer opportunities for optimizing material properties. While strength and ductility are commonly inversely related, nanotwinned polycrystalline copper has been shown to possess simultaneous ultrahigh strength and du...
