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.
