Are there two glass transitions in Fe–M–Y–B (M = Mo, W, Nb) bulk metallic glasses?

An anomalous glass transition was detected in differential scanning calorimetry (DSC) curves for Fe–M–Y–B (M = Mo, W, Nb) bulk metallic glasses, which has been investigated by DSC, X-ray diffraction and extended X-ray absorption fine structure. It is confirmed that the second inflection event in the supercooled liquid region is not a real glass transition, but rather a local atomic structure reordering, which is mainly caused by the strong affinity between B and other constituent elements as well as the repulsive interaction between M and Y.
