Fragility of superheated melts and glass-forming ability in Al-based alloys

A new concept, the fragility of superheated melt defined as, Graphics has been proposed in this work. It has been found that this kind of fragility value of liquid above liquidus temperature is closely related to the glass-forming ability in Al-based amorphous alloys. By calculation of the M, the glass-forming ability of Al-based amorphous alloys could be predicted prior to the preparation for amorphous solids. (C) 2005 Elsevier B.V. All rights reserved.
