Summary

Novel Zr-based bulk multi-component metallic glasses Zr-Cu-Ni-Al and Zr-Ti-Ni-Cu-Be have a wide supercooled liquid region and a high thermal stability. Oxidation studies on these alloys are important as the alloying elements, especially Zr, Ti, Al and Be have a high reactivity with oxygen. In the present study oxides of Zr46.75Ti8.25Cu7.5Ni10Be27.5 (Vitreloy 4, V4) and Zr65Cu17.5Ni10Al7.5 (Inoue alloy) formed under different conditions have been investigated using a combination of argon ion sputtering and X-ray Photoelectron Spectroscopy (XPS). In addition, in situ oxidation studies were carried out by exposing the clean specimen surface to pure oxygen doses up to 1000 Langmuir. The results show that Zr and Be (in the alloy V4) seem to be preferentially oxidised due to their segregation in presence of oxygen inhibiting the oxidation of other alloying elements especially Cu and Ni. The formation of the oxide films and the role of the alloying elements in the film formation are discussed using heats of formation and diffusion rates of the alloying elements.
