Electron irradiation-induced structural transformation in metallic glasses

abstract

• Microstructural evolution of Zr55Cu30Al10Ni5 and Cu50Zr45Ti5 metallic glasses under 200 keV electron irradiation has been studied in situ by transmission electron microscopy. Zr55Cu30Al10Ni5, which has a wider supercooled liquid region, is found to be stable under electron irradiation and no crystallization is observed up to an irradiation fluence of 8.7 1026 electrons m-2. In contrast, nanometer size crystalline Cu10Zr7 phases are formed in Cu50Zr45Ti5 under electron irradiation. The partial crystallization is attributed to irradiation enhanced atomic mobility. 2009 Acta Materialia Inc.
