The present letter aims to report the effect of supercooled liquid region on crystallization behavior of an Al85Ni5Y4Nd4Co2 metallic glass produced by rapid solidification of the melt. It is found that crystallization behaviors of this alloy above and below the glass-transition temperature are completely different. Formation of the primary nanoscale α-Al particles observed during continuous heating or after annealing above glass-transition temperature does not occur during isothermal annealing below glass-transition temperature when an unidentified intermetallic compound, and a-Al phases are formed simultaneously.
