“…The onset activation energy calculated of the Al 2 O 3 -GAP amorphous coating was 847.6 kJ/mol, which was greater than that of Al 2 O 3 -YAG amorphous coating. Figure 3b compares the initial crystallization activation energy obtained by the Kissinger method for some typical amorphous materials [22,[29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48]. Conspicuously, the crystallization activation energy of the Al 2 O 3 -GAP amorphous coating reported in this work was higher than that of almost all amorphous materials, which indicated that it was extremely difficult to overcome the energy barrier to precipitate crystalline phase in the Al 2 O 3 -GAP amorphous coating.…”

A novel Al2O3-GdAlO3 (GAP) amorphous ceramic coating was in situ prepared via atmospheric plasma spraying (APS). The Al2O3/Gd2O3 sprayable powders possessed excellent sphericity and fluidity after heat treatment at 1173 K without solid-phase reaction, which indicated that the Al2O3-GAP coating deposition process was significantly simplified. The Al2O3-GAP amorphous coating showed high glass transition temperature (1155.1 K), initial crystallization temperature (1179.2 K), local activation energy (847.6 kJ/mol) and nucleation resistance (88.3). Compared with almost all amorphous materials, the Al2O3-GAP amorphous coating possessed greater crystallization activation energy, which was conducive to its high-temperature microstructure stability. Furthermore, the hardness and elastic modulus of Al2O3-GAP coating fluctuated with a tiny range when increasing the nanoindentation depth from 500 nm to 2000 nm, which exhibited excellent uniformity of microstructure and mechanical performance of the coating. Therefore, the results showed that the Al2O3-GAP amorphous coating had a better potential for large-scale engineering application under harsh service conditions.

“…Thermal analysis methods are widely used to study crystallization kinetics in amorphous solids. There are opinions in the literature that the JMAK model has limited validity both in isothermal and non-isothermal conditions [87]. But many improved versions have been published [88,89].…”

A remarkable number of scientific papers are available in the literature about the bulk amorphous alloys and metallic glasses. Today, DSC is an essential tool for amorphous alloys research and development, and of course for quality assurance. In many cases, users seek to examine the determination of only one or two properties, although much more information can be obtained from the measurements. The research involved structural relaxation, Curie temperature, glass temperature, crystallization, phase separation, nanocrystalline volume fraction, melting point and liquidus temperature determination subjects and kinetics of microstructural transformations induced by thermal treatment. We collected and present the information that can be obtained with this technique and draws the reader’s attention to some potential problems related to data interpretation.

“…The factors that promote crystallization are temperature [15] , [16] , optical radiation [17] , [18] , [19] , [20] , [21] , chemical catalysis [22] , mechanical strain [23] , [24] , current stimulation [25] , electron and ion bombardment [26] , [27] , [28] , and external fields [29] , [30] . The effect of ultrasound on the crystallization process is mainly through the cavitation effect that drives the reversible reaction of dissolution–crystallization toward crystallization, thereby enhancing the primary and secondary nucleation processes of the system [31] , [32] , [33] .…”
