Characterization of crystallization kinetics of a Ni- (Cr, Fe, Si, B, C, P) based amorphous brazing alloy by non-isothermal differential scanning calorimetry

“…Although no sharp endothermic glass transition arrest is witnessed in this alloy, the measured glass transition temperature around 720 ± 2 K appears to be fairy reasonable for a Ni-based amorphous alloy of this generic composition [16]. The occurrence of the three distinct crystallization steps, albeit not new in the realm of metallic glasses, does not seem to have been investigated in this alloy before.…”

Influence of Pd on crystallization of Al–Ni–Sm-based ribbons

“…In the subsequent DSC scanning only R4 and R5 peaks have remained, thus the isothermal peaks account for R2 and R3 devitrification stages. The Arrhenius plots of the times for the maxima in the peaks [9] gave the apparent activation energies, E * A,i (see Table 2). The reason for the discrepancy between E * K,i and E * A,i is probably mostly of methodical origin, due to differences between heating rate and isothermal annealing regimes.…”

Detailed study of the crystallization behaviour of the metallic glass Fe75Si9B16

“…The crystallization kinetics is usually interpreted in terms of the standard nucleation-growth model formulated by Johnson-Mehl-Avrami (JMA) [16]. This model describes Fig.…”
