Metallic glasses (MGs) possess not only superior mechanical and functional properties but also excellent net-shape forming ability, which could be used for fabricating micro/nano-structures and micro/nano-devices through thermal plastic forming. However, it is very difficult to prepare large area uniform micro/nano structures due to the drawback of the commonly used free micro/nano-imprinting technique, where the flowing stress decreases along the radial direction of the imprinting surface. In order to overcome this problem, a die micro/nano-imprinting technique has been developed, which can effectively enhance the uniformity of the stress within the supercooled liquid of the glassy alloys during thermoplastic forming. By employing the newly developed die micro/nano-imprinting technique, large-area metallic glassy nanowire arrays, micro/nano-structures or devices in micro size have been successfully prepared. The present results indicate that die micro/nano-imprinting is an effective approach for fabricating large-area uniform nanowire arrays, micro/nano-structures and other nanodevices with full amorphous structure.
