Short-range order patterns in Mg66Zn29Ca5 metallic glass
Abstract
<p>Thanks to outstanding mechanical and chemical properties, metallic glasses have been recently alluring for biomedical applications. However, inadequate knowledge of atomic rearrangements as well as kinetics and mechanisms of crystallization prevents further microstructure improvement controlling the properties. In this work, we reveal that hierarchical transformations happen during the crystallization of Mg<sub>66</sub>Zn<sub>29</sub>Ca<sub>5</sub> metallic glass ribbons which were investigated using differential scanning calorimetry (DSC), electron microscopy (SEM and TEM), and X-ray diffraction (XRD). The activation energies corresponding to the crystallization of the glassy ribbons were evaluated by different thermodynamic models, i.e., Kissinger, and Augis and Bennett analysis. Our findings prove the formation of short-range order patterns in Mg<sub>66</sub>Zn<sub>29</sub>Ca<sub>5</sub> metallic glass with a unit size of ∼ 0.247 nm. Furthermore, the applied heating rate affects the glass transformation only slightly but accelerates the growth process quickly. The phase transformations occurring in annealed samples were studied by XRD, proving that crystallization starts with the formation of α-Mg + metastable Mg<sub>51</sub>Zn<sub>20</sub>. The metastable Mg<sub>51</sub>Zn<sub>20</sub> gradually transfers to Mg<sub>7</sub>Zn<sub>3</sub> with increasing temperature, and also Ca<sub>2</sub>Mg<sub>5</sub>Zn<sub>13</sub> precipitates. Close to the end of crystallization, Ca<sub>2</sub>Mg<sub>6</sub>Zn<sub>3</sub> precipitates by consuming Ca<sub>2</sub>Mg<sub>5</sub>Zn<sub>13</sub>. The Johnson–Mehl–Avrami–Kolmogorov (JMAK) model was employed to obtain the Avrami exponent of the crystallization reaction. The average slope of the Avrami plots is close to 2, indicating that crystallization progresses with diffusional growth and decreasing nucleation rate.</p>
