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.…”

“…Zr 63.5 Al 10.7 Cu 10.7 Ni 15.1 Table 1 The characteristic temperatures in the bulk metallic glasses. and Zr 61.5 Al 10.7 Cu 13.65 Ni 14.15 bulk metallic glasses [1,2]. Parameter β expresses the sensitivity of the characteristic temperatures to the heating rate.…”

Fabrication of Ti–Cu–Ni–Al amorphous alloys by mechanical alloying and mechanical milling

“…Generally, the temperature for onset of crystallization is strongly associated with the nucleation process, and the peak temperature is related to the growth process [26]. The apparent activation energies of characteristic temperatures can be determined from the peak shifts of the heating DSC curves at different heating rates and using the Kissinger equation [27] equation [28].…”

Influence of casting temperature on the thermal stability of Zr-based metallic glasses

“…Therefore, it is vitally important to understand the thermal stability of metallic glasses. So far, a lot of research work has been performed on thermal stability of metallic glasses, such as the thermal stability of different alloy systems [11][12][13][14][15] and the microalloying effects on thermal stability [16][17][18]. The fluxing technique has been successfully used in the synthesis of different amorphous * Corresponding author.…”
