Non isothermal kinetics of crystallization and DSC analysis of FeNi based metallic glasses

A study on microstructure, magnetic properties and kinetics of the nanocrystallization of Fe40Ni38B18Mo4 metglass

“…The E value of MS2 was also in good agreement with the reported values in literature [19,20]. The E value for MS1 obtained by Kissinger approach was in close agreement with those obtained by Kurajica et al [21] and Antonione et al [17]. The activation energy for MS1 and MS2 reported in literature [17][18][19][20][21][22] has been presented in Table 4.…”

“…The average enthalpy changes (DH) of the crystallization process were computed using DSC peaks (area under curve) obtained with four different heating rates. These values were in close agreement with the values reported by Antonione et al [17]. Results thus obtained for primary crystallization (MS1) and secondary crystallization (MS2) processes have been tabulated in Table 1.…”

“…The E value for MS1 obtained by Kissinger approach was in close agreement with those obtained by Kurajica et al [21] and Antonione et al [17]. The activation energy for MS1 and MS2 reported in literature [17][18][19][20][21][22] has been presented in Table 4. It can be seen from this table that there was a large scatter in the E values determined by different approaches for both MS1 and MS2 and these were ranging from 280 to 451 kJ/mol for MS1 and from 270 to 403 kJ/mol for MS2.…”

Thermally induced crystallization of amorphous Fe40Ni40P14B6 alloy

“…Amorphous alloy Fe 40 Ni 40 P 14 B 6 is potentially useful for different applications [26], and, therefore, it has been a subject of many studies [26][27][28][29][30][31][32][33][34][35][36][37]. An examination of the structure of the alloy sample isochronally heated at 40 Kmin -1 up to 723 K revealed that a completely crystalline sample contained (Fe,Ni) 3 (P,B) and γ-(Fe,Ni) phases [27].…”

On the crystallization kinetics and micro-structural transformations of Fe40Ni38B18Mo4 alloys

“…Antonione et al [11] was the first to report the crystallization kinetics of metglas. Using nonisothermal calorimetric studies they reported activation energies of &3.067 eV/atom and &3.46 eV/atom respectively for the two phases.…”
