a, b TEM investigation reveals the amorphous structure of 120 nm Ni-BMG nanowires, formed through homogeneous flow. a Overview of a nanowire formed through homogeneous flow where the selected area electron diffraction (SAED) pattern suggests an amorphous structure. b HRTEM image and FFT pattern of the nanowire region marked in a. c–e Transition from amorphous to crystalline diffraction patterns along the 20 nm Ni-BMG nanowires formed outside of the homogeneous flow region. c SAED over nanowire reveals the presence of crystalline phases. d HRTEM image of marked region in c. e FFT patterns from marked regions in d reveals a transition of the structure from amorphous to crystalline along the growth direction of the nanowire.
