Nanoscale Periodic Morphologies on the Fracture Surface of Brittle Metallic Glasses G. Wang,1 D. Q. Zhao,1 H.Y. Bai,1 M. X. Pan,1 A. L. Xia,1 B. S. Han,1 X. K. Xi,2 Y. Wu,2 and W. H. Wang1,* 1 Institute of Physics, Chinese Academy of Sciences, Beijing 100080, People’s Republic of China 2 Department of Physics and Astronomy, University of North Carolina, Chapel Hill, North Carolina 27599-3255, USA (Received 20 September 2006; published 5 June 2007) Out-of-plane, nanoscale periodic corrugations are observed in the dynamic fracture surface of brittle bulk metallic glasses with fracture toughness approaching that of silica glasses. A model based on the meniscus instability and plastic zone theory is used to explain such dynamic crack instability. The results indicate that the local softening mechanism in the fracture is an essential ingredient for controlling the formation of the unique corrugations, and might provide a new insight into the origin of fracture surface roughening in brittle materials.
