Abstract

Rapid solidification of the Zr3Al liquid alloy allows retention of the high temperature β–Zr solid solution with bcc structure. Mechanical grinding is shown to amorphize this metastable phase very easily. Calculations show that the retained bcc phase has a free energy above that of the amorphous phase. The density of bcc Zr3Al at room temperature is found to be 2% lower than that of its equilibrium L12-ordered fcc structure as determined from their respective lattice parameters. The bcc phase thus represents a 2% volume expansion with respect to the fcc structure.
