Abstract

Cu60Zr30Ti10 (at.%) metallic glass was prepared in two forms: as a rod of diameter 3 mm and length of 26 mm and as a thin ribbon wide 5 mm and thick 35 μm. Chemical composition of the alloys was as certain by Scanning Electron Microscopy (SEM) coupled with EDX analysis. Phase composition was evaluated by X-ray diffraction (laboratory and high-energy XRD at synchrotron). Thermal stability of rod and ribbon samples was investigated by Differential Scanning Calorimetry (DSC), where thermal characteristics such as glass transition temperature, crystallization temperature and subsequent supercooled liquid region were compared for the two materials. Based on performed in-situ high temperature X-ray diffraction experiment we were able to determine changes in phases composition of the Cu60Zr30Ti10 amorphous alloys upon an annealing.
