Abstract:
In this work, we correlate the microstructure and passivation of the Al 95− x Ni x Y 5 lightweight glassy ribbons ( x = 7 and 10) using various techniques. The overdosed Ni ( x = 10) can increase the melt viscosity and then deteriorate its glass-forming ability (GFA), ribbon formability, and Y-depleted extra layer formation. Consequently, the overdosed Ni weakens the passivation stability and corrosion resistance of the as-spun ribbon. The key role of the overdosed Ni can form a strong network and crystalline grain boundary in the amorphous matrix, which can transport Y and O to participate in the oxidation. These results can help us explore a valuable method for designing new Al-based metallic glasses.
