Description
Summary:The aim of the study was to analyze the crystallization kinetics of the Mg<sub>72</sub>Zn<sub>28</sub> metallic glass alloy. The crystallization kinetics of Mg<sub>72</sub>Zn<sub>28</sub> 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 Mg<sub>12</sub>Zn<sub>13</sub> 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 <i>E</i><sub>g</sub> = 176.91, <i>E</i><sub>x</sub> = 124.26, <i>E</i><sub>p1</sub> = 117.49, and <i>E</i><sub>p2</sub> = 114.48 kJ mol<sup>−1</sup>, respectively.
