Abstract

The crystallization behavior of Zr₆₃Al_7.5Cu_17.5Ni₁₀B₂ amorphous Alloy was studied by means of scanning differential calorimetry (DSC), X-ray diffraction (XRD), and transmission electron microscopy (TEM). A single stage transformation of the amorphous phase forming a Zr₂Cu-type crystalline phase was observed. Kinetics for such single stage crystallization was analyzed by means of Johnson-Mehl-Avrami equation and discussed regarding to the value of Avrami exponent. In addition, the cube of crystal size presents a linear relationship with isothermal annealing time. This indicates that the crystallization process of Zr₆₃Al_7.5Cu_17.5Ni₁₀B₂ amorphous alloy belongs to thermally activated process of Arrhenius type. From the HRTEM analysis, small amount of Zr₂Cu-type crystals in the nano-scale dimension (10-20 nm) were observed to precipitate from the amorphous matrix upon the early stage of isothermal annealing the amorphous alloy at the temperature between the glass transition (T_g) and the onset crystallization temperature (T_x).
