“…Eq. (7) indicates that the apparent activation energy of glass transition is directly proportional to crystallization temperature, but inversely to glass transition temperature in the present Fe based amorphous alloys, It is very different from previously reported results [5,6], in which apparent activation energy of glass transition was deduced from structural relaxation model to be approximately directly proportional to glass transition temperature. In order to confirm correlation between E g and T g in the Fe based amorphous alloy, the E g as a function of T g for the amorphous FCZBN and FBZN alloys is plotted on Fig.…”

“…Its physical meaning and correlation with T g , T x and GFA have been interesting subjects in amorphous alloy investigations. Some efforts have been made to set up a correlation between E g and T g [5,6], or characterize GFA by combining some parameters, which can be measured by the nonisothermal scanning technique together with some suitable method or equation [7,8]. However, it is still lacking in comprehensive understanding of E g and relationships between T g , T x , E g and GFA.…”

“…This rapid crystallization also prevents one from measuring the viscosity and other properties of its equilibrium liquid. Examples of materials that crystallize rapidly soon after the onset of their T g endotherm are vapor-deposited CCl 4 (see Table in ref ) and a variety of hydrocarbons, hyperquenched metal alloys (atomic glasses of high fictive temperatures), , ,, ASW, HGW, ,, mechanically amorphized solid 1,3,5-tri-α-naphthylbenzene (a molecular glass), , etc. When such amorphous solids already contain crystal nuclei or microcrystals or both on their surface or in their bulk, they crystallize even more rapidly on heating, as, for example, some glassy metal alloys, and ASW, HGW, ,, and mechanically amorphized solids. …”

“…It should be noted that several glasses have been found to crystallize also at T below their T g , but only after having been kept for a long period at that T . Among these are a few Ni-based, hyperquenched metal alloy glasses, , which crystallize incongruently and relatively slowly over a period of several hours to several days when kept at temperatures slightly below T g . Our scrutiny of the calorimetric data on these glasses has shown that the ratio of the crystallization temperature of their unannealed state to T g is 0.99 for Ni 75 P 16 B 6 Al 3 , 0.91 for Fe 40 Ni 40 B 20 , and 0.97 for Fe 40 Ni 40 P 14 B 6 .…”
