金属玻璃纳米线是在通过常规机械测试产生的断口表面自发形成的。纳米线的存在与高温下粘度较小的一维弯月面构型以及金属玻璃较宽的过冷液相区直接相关。电子显微镜观察显示了薄膜的直径、长度和非晶态结构，能量色散X射线显示了薄膜的化学成分。此外，我们还发现圆脊是由纳米管构成的。非晶态纳米结构的发现不仅提供了对断裂过程的基本理解，也为纳米工程的构建提供了新的视角。
Metallic glass nanowires were spontaneously created on the fracture surfaces that were produced by a conventional mechanical test. The presence of the nanowires is directly related to the one-dimensional meniscus configuration with a small viscosity at high temperatures and to the wide supercooled liquid region of the metallic glass. The electron microscopic observations demonstrate the diameters, the lengths, and the amorphous structural states, and the energy dispersive X-ray reveals the chemical components. In addition, we found that round ridges are constructed from nanotubes. The finding of amorphous nanostructures not only provides a fundamental understanding of fracture processes but also gives a new insight into nanoengineering constructions.
