Ultrasonic Welding of Fe₇₈Si₉B₁₃ Metallic Glass

Abstract:

The solid bonds of multi-layer Fe₇₈Si₉B₁₃ metallic glass foils have successfully been produced by ultrasonic welding technology. The interface of weld joints was investigated by Optical micrograph (OM), scanning electron microscope (SEM) observation, micro-area X-ray diffraction (micro-XRD) and differential scanning calorimetry (DSC) analysis. The results demonstrate that no visible interface and defects were observed and the amorphous structure was maintained. The thermal properties of the joined metallic glasses were the same as that of the parent metallic glass. The formation of joining metallic glasses was attributed to the superplastic flow and the thermal stability at elevated temperatures in the supercooled liquid state. Ultrasonic welding as tack welding proposes an effective method for the preparation of bulk metallic glasses (BMGs) and lays the foundation for its future applications.
