Preparation and properties of a bulk metallic glass and high-entropy alloy composite

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).…”

Microstructure, thermodynamics and compressive properties of Al0.5CoCrCuFeNi-X (X=V,Si,VSi) high-entropy alloys

“…Thermodynamically, the high entropy greatly reduces the Gibbs-free energy of simple solid–solution phases at an elevated temperature. It makes the chemically ordered intermetallic compounds less competitive [4,14].…”
