We discuss the effect of Sn addition on anomalous glass transition behavior in Cu-Zr bulk-forming metallic glasses. We found that an unusual endothermic reaction in Cu55Zr40Sn5 ribbon can originate from the growth reaction of quenched-in nuclei from 0.4 nm to 3.7 nm in the supercooled liquid region. This anomalous devitrification may prove useful for the synthesis of a novel composite with uniform atomic/nanometer scale heterogeneity modulated by controlling cooling rate as well as by tailoring alloy composition.
