Reversible cyclic deformation mechanism of gold nanowires by twinning–detwinning transition evidenced from in situ TEM

Reversible deformation of metal nanowires accommodating large strains by twinning-detwinning


In situ studies of deformation in metal nanowires have yielded interesting results, as recently published in Nature Communications. An international research team performed cyclic loading on gold nanowires and observed twinning and detwinning phenomena, respectively caused by tensile and compressive loading, and elucidate the underpinning mechanism by molecular dynamics simulations.
