Effect of Specimen Preparation Method on Transmission Electron Microscope Investigation in a Bulk Metallic Glass

Abstract:

In this paper, high resolution transmission electron microscopy (HRTEM) has been used to observe a Zr_41.25Ti_13.75Ni₁₀Cu_12.5Be_22.5 (at. %) bulk metallic glass (BMG) prepared from different methods, i.e. ion milling and electropolishing. The ion thinning brings out the white bulb pattern on the specimen surface and induces localized temperature increasing. The electropolishing does not influence microstructure of the amorphous phase. A new preparation technique of grinding method is introduced. For BMG, the electropolishing and grinding are the better method for TEM specimen preparation as compared with the ion thinning.
