The study of crystallization of Mg-based bulk metallic glass (BMG)

Bulk metallic glass (BMG) is an excellent candidate for future material in various applications due to its superior physical and mechanical properties. The characterization of the crystallization evolution of Mg58Cu31Gd11 has been performed using in-situ synchrotron radiation technique. Differential scanning calorimeter (DSC) and laboratory X-ray diffraction were also implemented to confirm the crystallization during heating at 20 °C/min. The glass transition temperature (Tg) was resolved and the occurrence of two stages crystallization was found during the process. The Mg2Cu growth accompanies the crystallization process and occurrence of more complex compound is suggested. (paper)
