Abstract

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.
