综述了块体金属玻璃的热塑性拉伸技术的最新进展。拉伸与模板化压花的结合使得能够制造高深宽比的纳米结构阵列，而早期的拉伸方法仅限于单个纤维。两步拉深可以制造出金属玻璃结构，如在衬底上垂直排列的纳米线、纳米级拉伸试件、中空微针、螺旋轴和微纱线，这些都是用其他热塑性成形工艺难以制造的。这些几何结构将为大块金属玻璃在传感器、光学吸收、经皮给药和高通量尺寸效应表征等领域开辟新的应用领域。在这篇文章中，我们回顾了基于模板的热塑性拉伸在大块金属玻璃中的出现。综述了实验装置的发展、绘制过程的定量描述以及绘制方法的通用性。
This study summarizes the recent progress in thermoplastic drawing of bulk metallic glasses. The integration of drawing with templated embossing enables the fabrication of arrays of high-aspect-ratio nanostructures whereas the earlier drawing methodologies are limited to a single fiber. The two-step drawing can produce metallic glass structures such as, vertically aligned nanowires on substrates, nanoscale tensile specimens, hollow microneedles, helical shafts, and micro-yarns, which are challenging to fabricate with other thermoplastic forming operations. These geometries will open new applications for bulk metallic glasses in the areas of sensors, optical absorption, transdermal drug-delivery, and high-throughput characterization of size-effects. In this article, we review the emergence of template-based thermoplastic drawing in bulk metallic glasses. The review focuses on the development of experimental set-up, the quantitative description of drawing process, and the versatility of drawing methodology.
