In the present study, we propose a novel approach to exploring glassy alloys with high oxidation resistance in their supercooled liquid region. The oxidation resistance of the Zr-based metallic glasses can be strongly enhanced when the glassy surface is covered by a native amorphous metal oxide film. We have investigated the effect of codoping Al and Ti into the amorphous zirconia on glass stability...
The oxidation behavior of Ti50Cu50 metallic glass has been investigated. When the oxide is in amorphous state blow the glass transition temperature, the diffusion rate of Ti ion from the matrix controls the growth rate of the oxide layer. With the increase of thickness, the amorphous oxide is crystallized into TiO2, which grows in inward direction by diffusion of oxygen ion through the oxide layer...
