Abstract

The present paper aims to report the effect of partial or full replacement of Y in the Al85Y8Ni5Co2 alloy by other rare-earth (RE) metals. Influence of small amount of Zr, Pd or Cu additions was also studied for comparison as these elements also have a negative heat of mixing with Al. The studied alloys were produced by rapid solidification of the melt. Glass-forming ability, crystallization behaviour and stability of the supercooled liquid have been studied by X-ray diffraction (XRD) and differential scanning calorimetry (DSC). It has been found that additions of RE metals have not caused critical changes of the properties of the Al85Y8Ni5Co2 alloy while small amount of Pd or Cu additions significantly change its crystallization behaviour and destabilize the supercooled liquid. Addition of more than about 3 at.% of Zr causes precipitation of the primary Al3Zr phase during rapid solidification.
