Attempt to depict glass forming ability of bulk metallic glasses using the criterion of the total relaxation time at the glass transition

Compositional dependence of thermal stability, glass-forming ability and fragility index in some Se–Te–Sn glasses

“…All these values are closed to 0.5 and lie in the last accepted range. In addition to the present work, several works [12,13,36,37] showed that T rg is almost constant value (mainly = 2/3) for all glassy alloys. Hence it does not reflect any difference in the GFA among different compositions of the studied glasses.…”

“…Efforts [13][14][15][16][17][18] have been made to study and to relate thermal stability and glass-forming ability of chalcogenide glasses with their composition because of its importance in determining the utility of chalcogenide alloys as recording materials or in other practical applications. Further, the composition dependence of thermal stability, glass-forming ability and other thermal parameters yields valuable information about the evolution of network connectivity and the network topological thresholds.…”

Rare earth based bulk metallic glasses

“…This broadness may be ascribed to the smearing of the density of states associated with the short mean free path in the disordered alloys. Interestingly, due to its sensitivity to the electronic and atom structure, the resistivity in the normal state of La-based REBMGs and other BMG families can be used to monitor the structure evolution during relaxation, glass transition and crystallization, and even evaluate the glass-forming ability [168][169][170][171][172][173][174].…”

An Insight into the Correlation between Chemical Composition Changes of Aluminum-Iron-Polyphosphate Glasses and Thermal Properties

“…The more time the glass transition needs, the higher is the glass-forming ability. Therefore, the total relaxation time for the glass transition (τ) can be approximated as τ = ΔT g/ β, where ΔT g is the width of the glass transition region (ΔT g =T g ″-T g ′), and β is the heating rate [ 40 , 41 , 42 ]. The estimated relaxation time as a function of glass composition is presented in Figure 9 .…”
