Structural and Crystallization Characteristics of Cu-Based Metallic Glass Powders Produced by Gas Atomization

Abstract:

In this work, Cu₅₀Zr₄₃Al₇ metallic glass powders were produced by gas atomization method. The structure and crystallization characteristics of the as-prepared powders with different particle size distributions were studied in detail. The amorphous state of the alloy powders was confirmed by X-ray diffraction (XRD), in which amorphous phase formed. The scanning election microscopy (SEM) result showed that the selected metallic glass powder performed excellent owned good spherical morphology, which was also observed on an optical microscope (OM). At the same time, the particle size distributions ranging from 20 μm to 200 μm of as-prepared metallic glass powders were determined by laser diffraction. Moreover, the crystallization behavior of the Cu₅₀Zr₄₃Al₇ metallic glass powders was investigated by differential scanning calorimetry (DSC).
