High-entropy bulk metallic glasses (HE-BMGs) are novel bulk alloys combined the multi-principal component characteristics of high-entropy alloys with the long-range disordered atomic stacking characteristics of metallic glass. HE-BMGs, like conventional BMGs, are thermodynamically in a metastable state. However, the crystallization processing of HE-BMGs is different from the conventional BMGs. In this paper, non-equiatomic ZrxTiNiCuBe (x=1.5, 2, 2.5, 3, 3.5at.%) HE-BMGs are prepared by copper mold casting method, and their crystallization kinetics was studied by differential scanning calorimeter (DSC) under both non-isochronal and isothermal conditions. The non-isothermal crystallization kinetics of Zrx HE-BMGs showed a multiple-stage processing. The characteristic temperatures increased with the increase of the heating rate, showing obvious kinetics effects. The activation energy calculated by the Kissinger equation showed Eg>Ex>Ep1,indicating that the overcoming the energy barrier for the rearrangement of was more difficult than atoms nucleation process and the grain growth process of crystallization. The activation energy of crystallization event is Ep1
