Characterization of the Oxide Layer Formed on the Cu-Zr Based Metallic Glass during Continuous Heating

Abstract

In the present study, the oxidation behavior of and metallic glasses has been investigated using transmission electron microscopy with a particular attention on the oxidation behavior in the supercooled liquid state. Identification of the oxidation product after continuous heating treatment shows that in metallic glass, with the monoclinic structure forms on the supercooled liquid as well as on the crystallized matrix. On the contrary, in metallic glass, with the tetragonal structure forms on the supercooled liquid, but that with the monoclinic structure forms on the crystallized matrix. The result indicates that the metallic glass exhibits far better oxidation resistance in the supercooled liquid state than the metallic glass.
