Abstract
The crystallization processes of amorphous Zr75Cu27Al8 alloy, both fro m amorphous state and supercooled liquid, were investigated. It was ma inly controlled by the growth of pre-existing quenched-in three-dimens ional nuclei with a constant growth rate. It was observed that the act ivation energy is much higher in the transition from amorphous state t han that from supercooled liquid. The crystallization product from bot h initial states consists of the b.c.t. Zr2Cu phase and an unknown pha se with f.c.c. structure. (C) 1998 Elsevier Science B.V. All rights re served.
