摘要：
Structural modification in a Zr-based metallic glass caused by irradiation with 7 MeV Xe26+ ions was investigated. Needle-like nanocrystalline structures, formed under ion irradiation, consist of Cu10Zr7 phase (primary) and/or minor (NixCu1-x)(10)Zr-7 phase. The formation of needle-like nanocrystals suggested an anisotropic atomic diffusion caused by ion irradiation. (C) 2014 Elsevier Ltd. All rights reserved.
