Cu64Zr36 amorphous ribbons were prepared by melting-spun technique. The crystallization process and kinetics were investigated by isothermal annealing at different temperature, DSC and XRD. The results show that the crystallization process is that Cu10Zr7 would precipitates primarily, then CuZr2. The activation energies of glass transition and crystallization are 433.7 kJ/mol and 603 kJ/mol, respectively.
