The present letter aims to report the effect of supercooled liquid region on crystallization behavior of an Al[sub 85]Ni[sub 5]Y[sub 4]Nd[sub 4]Co[sub 2] 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 α-Al phases are formed simultaneously. © 2001 American Institute of Physics.

    A linear correlation of fragility parameter D* with supercooled liquid region width ΔTx for Ca-based bulk metallic glasses (BMGs) was revealed. This relationship is found in La- and Zr-based BMGs as well and extended to several glass-forming systems. The origin of this phenomenon lies in the...
