Abstract

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.
