Comparative study of non-isothermal crystallization kinetics between Fe80P13C7 bulk metallic glass and melt-spun glassy ribbon

Thermal Stability and Phase Transformations of Multicomponent Iron-Based Amorphous Alloys

“…For all the crystalline phases in all the alloys examined, relatively high E a values are obtained, probably as a result of cooperative participation of a large number of atoms in each step of the transformations [36]. The E a values, obtained using various methods [19,[21][22][23][24], are in agreement with the literature overall E a values corresponding to the similar systems [36,50,51].…”

Thermally induced crystallization of amorphous Fe40Ni40P14B6 alloy

“…In a study of crystallization in As 40 Te 50 In 10 glass, Gaussian function was used to separate overlapped DTA peaks and determine apparent activation energy and reaction order corresponding to the individual crystalline phases [20]. Gaussian function was also applied to deconvolute overlapped crystallization DSC peaks of Fe 80 P 13 C 7 metallic glass, in order to deduce crystallization mechanism from the local values of Avrami exponent [21]. By fitting different mathematical functions to the curves corresponding to different kinetic models, Perejόn et al suggested the use of Fraser-Suzuki function as the most appropriate deconvolution function [22].…”

Effect of Ge Addition on Magnetic Properties and Crystallization Mechanism of FeSiBPNbCu Nanocrystalline Alloy with High Fe Content

“…Therefore, the small, dense and uniform nanocrystalline structure of the annealed Ge2 alloy may account for its excellent magnetic properties. The effective activation energy (E) of the alloys can be used to describe the difficulty of the crystallization process [24]. The effective activation energy can be determined by various methods [25][26][27]; here, it is calculated by the Kissinger equation as follows [26,27]:…”
