Stripes with a period of 87 nm appear in the mirror region of the fracture surface of metallic glasses. Two competing failure mechanisms of immediate meniscus instability and cavitation mechanism near the crack tip control the fracture process of metallic glasses and the formation process of nanostripes.
在金属玻璃断口的镜面区域出现了周期为 87nm 的条纹。在临近裂纹尖端的弹状失稳和空化机制这两种竞争失效机制控制着金属玻璃的断裂过程和纳米条纹的形成过程。
