Kinetic study of non-isothermal crystallization in Fe78Si9B13 metallic glass

Glass transition kinetics and crystallization mechanism in Se90Cd8Bi2 and Se90Cd6Bi4 chalcogenide glasses

“…The average values of n, for the two glasses, are calculated from the last equation and listed in Table 3 this table, it is clear that the values of n are not integers. A noninteger value of n indicates that two crystallization mechanisms were working during amorphous-crystalline transformation [41]. The obtained values of Avrami exponent (n) indicate that the crystal growth, in the two studied samples, occurs in one dimension (or growth from surface nuclei).…”

Thermal stability of (Ce0.72Cu0.28)90‐xAl10Fex (x = 0, 5 or 10) bulk metallic glasses

“…These effective activation energies observed in the Cebased bulk metallic glasses are lower compared with those reported in other based amorphous materials, such as Ybased [20], Fe-based [8,9], Co-based [21], Cu-based [22] and Zr-based bulk metallic glasses [1,3]. For crystallization process in bulk metallic glass, compared with lower effective activation energy, the materials are of the higher effective activation energy need higher thermal activated temperature.…”

“…Recently, there have been many reports on thermal properties and mechanical properties of bulk metallic glasses (BMGs), such as Zr-base [1][2][3], Pdbase [4,5], Ti-base [6,7] and Fe-base BMG [8,9]. These bulk metallic glasses present excellent resistance with respect to crystallization in the supercooled liquid region.…”

Optimization of soft magnetic properties and crystallization in FeAgNbSiB, FeAgNbB and FeAgCoNbB amorphous alloys

“…Because of some unique properties (very high magnetic permeability and also resistivity) these alloys have found nowadays industrial applications in the field of electrical engineering as magnet cores or different kind of sensors [1][2][3][4][5]. Moreover magnetic properties of amorphous alloys based on iron can be significantly improved by applying a specific thermal annealing [6][7][8][9].…”
