 Abstract
The crystallization behavior in the and amorphous alloys has been investigated. As-quenched amorphous phase decomposes by simultaneous formation of Al and intermetallic phase at the first crystallization step, while as-quenched amorphous phase decomposes by forming Al nanocrystals in the amorphous matrix. The density of Al nanocrystals is extremely high and the size distribution is homogeneous. Such a microstructure can result from rapid explosion of the nucleation event in the amorphous matrix or growth of the preexisting nuclei embedded in the as-quenched amorphous matrix. The final equilibrium crystalline phases and their distribution at 873 K are exactly same in both and alloys.
