The aim of the study was to analyze the crystallization kinetics of the MgZn metallic glass alloy. The crystallization kinetics of MgZn metallic glass were investigated by differential scanning calorimetry and X-ray diffraction. The phases formed during the crystallization process were identified as α-Mg and complex MgZn phases. Activation energies for the glass transition temperature, crystallization onset, and peak were calculated based on the Kissinger model. The activation energy calculated from the Kissinger model was = 176.91, = 124.26, = 117.49, and = 114.48 kJ mol, respectively.
