The isochronal and isothermal DSC annealing techniques have been employed to investigate the crystallization behavior of a newly developed Ti16.7Zr16.7Hf16.7Cu16.7Ni16.7Be16.7 high entropy bulk metallic glass. In non-isothermal condition, the activation energies for glass transition, onset and the first crystallization process were determined by Kissinger equation, to be 331.8±8.0, 215.3±4.5 and 245.5±6.3 kJ/mol, respectively. The isothermal kinetics was modeled by the Johnson-Mehl-Avrami (JMA) equation. During the crystallization process, the isothermal activation energy calculated by the Arrhenius equation changes little with an average value of 259.9 kJ/mol. The Avrami exponent is in the range from 1.81 to 2.04, indicating that the crystallization process is mainly dominated by growth of particles with a decreasing nucleation rate.
