摘要：

The process of transition of the Zr55Cu30Al10Ni5 bulk amorphous alloy from an amorphous into a crystalline state has been investigated by using differential scanning calorimetry and dynamic mechanical analysis. The parameters of crystallization of the alloy, such as glass transition temperature (T-g), crystallization temperature (T-x), activation energy of crystallization (E-a), solidus and liquidus temperatures (T-sol, T-liq), crystallization enthalpy (Delta H-x), melting heat (Delta H-m) and solidification heat (Delta H-sol) have been determined. The behavior of the storage modulus (E-I), the loss factor (tan delta) with a temperature change from room temperature to 873 K has been studied. The phase structure of the alloy after crystallization was investigated by using X-ray diffraction. (C) 2019 Elsevier B.V. All rights reserved.
