Abstract: A model Zr41.25Ti13.75Ni10Cu12.5Be22.5 (at.%) bulk metallic glass (BMG) is selected to explore the structuralevolution on the atomic scale with decreasing temperature down to cryogenic level using high energy X-raysynchrotron radiation. We discover a close correlation between the atomic structure evolution and thestrength of theBMGand find out that the activation energy increment of the concordantly atomic shifting atlower temperature is the main factor influencing the strength. Our results might provide a fundamentalunderstanding of the atomic-scale structure evolution and may bridge the gap between the atomic-scalephysics and the macro-scale fracture strength for BMGs.
