Abstract

The present study shows that the as-melt-spun Zr₂₈Y₂₈ Al₂₂Co₂₂ amorphous ribbon undergoes solid-state phase separation into Zr- and Y-rich regions when heated below the glass transition temperature (T_g). Dynamic mechanical measurements show that two types of low-temperature relaxation occur below T_g, and transmission electron microscopy observation confirms the solid-state phase-separated microstructure. The diffusion coefficient of solid-state phase separation is calculated by the measured separation distance.
