Structural relaxation, beta relaxation and crystallization processes of the Cu53Y42Al5 metallic glass were studied in the present work. X-ray diffractometry was used to study the structure of the samples. Phase transformations were studied by differential scanning calorimetry by using a power compensated type differential calorimeter. Cu-mould casting resulted in the formation of crystalline samples while fully glassy Cu53Y42Al5 alloy samples were produced by melt spinning at a high cooling rate of about 105-106 K/s. This glassy alloy is characterized by strong beta relaxation and low activation energy values for crystallization and relaxation in comparison with other metallic glasses studied earlier.
