Temperature-dependent strain localization and texture evolution of highly nanotwinned Cu

Strong differences in the plastic strain and texture development in high purity nanotwinned copper foils deformed to failure in tension at ambient and liquid nitrogen (LN) temperatures have been observed. High energy microdiffraction patterns for the room temperature (RT) sample showed two distinct deformation regions relative to its fracture surface: d 500 μm; while for the sample deformed at 77 K, three distinct regions were observed: d
