High entropy metallic glasses: Glass formation, crystallization and properties

Fatigue database of complex metallic alloys

“…The numbers of major elements are generally n ≤ 3 for MGs and ≥3 for MPEAs. High-entropy MGs ( n > 3) are also studied and some of them feature similar chemical composition as those of MPEAs 77 .…”

Crystallization kinetics, microstructure evolution, and mechanical responses of Cr-Co alloys

“…Previous results have revealed that the rate of nucleation and growth of crystals in the alloy is highly dependent on the cooling rate, which generally determines the degree of crystallinity [13][14][15][16]. Metallic glasses, which are frequently generated through rapid solidification and present amorphous structures with shortrange order, have become a consistently active field owing to their attractive properties and intriguing origins [17][18][19][20][21]. Collaborated with experimental proof, the simulation results could not only predict the exact polymorph that the system adopts under various external conditions, but they are also capable of providing a clear picture of the crystallization pathway at an atomic level, which helps to better understand the mechanisms of crystal growth and the formation of different phases [22][23][24][25][26][27][28][29].…”

Tuning Non-Isothermal Crystallization Kinetics between Fe20Co20Ni20Cr20(P0.45B0.2C0.35)20 High-Entropy Metallic Glass and the Predecessor Fe75Cr5P9B4C7 Metallic Glass

“…As typical metastable alloys, the metal-metalloid-type alloys of Fe-P-based highentropy metallic glasses (HEMGs) and the predecessor metallic glasses (MGs) normally possess superior merits of excellent soft-magnetic properties, visible plasticity, outstanding corrosion resistance, along with high strength and hardness, which are beneficial for the flourishing of theoretical and engineered explorations of the alloys [1][2][3][4][5][6][7]. Nevertheless, it is worth noting that the metastable alloys of HEMGs and MGs will natively change to the stable crystalline counterparts, and it becomes less resistant at elevated temperatures, ineluctably affecting the structures and performances of the alloys [1,2,[8][9][10][11][12][13][14][15][16][17].…”

Consequently, it is greatly imperative to research the crystallization behaviors or kinetics of HEMGs and the predecessor MGs using different annealing strategies, as this can provide key evidence for dissecting the formation of the alloys as well as the corresponding correlations, controlling the structures and performances of the alloys and fabricating glassy crystalline composites with prominent prospects [8][9][10][11][12][13][14][15][16][17].…”

“…Generally, research on the non-isothermal crystallization behaviors or kinetics for various MGs is attracting more interest [1,[8][9][10][11][12][13][14][15][16][17]. During the research, the alloys were continuously heated to a certain temperature until the completion of crystallization under different heating rates, which was executed by differential scanning calorimetry (DSC).…”
