Homogenization of a metallic melt: Enhancing the thermal stability of glassy metal
2023, Materials Today PhysicsAn atomistic study of the structural changes in a Zr–Cu–Ni–Al glass-forming liquid on vitrification monitored in-situ by X-ray diffraction and molecular dynamics simulation
2020, IntermetallicsCitation Excerpt :The atomic structure of these BMGs at room temperature was studied in detail [6,7]. Here one should mention that anomalous variation in a liquid viscosity in the vicinity of Tl and above it was observed for Fe- [16,17] and Zr- based glass-forming alloys [18] as well as for Al-based crystalline alloys [19]. The authors stated that liquid metallic alloys can have various structural states and significant overheating is required to dissolve clusters inherited from the solid state and to reach equilibrium liquid structure.
Long – Time relaxation in liquid eutectics
2019, Journal of Alloys and CompoundsCitation Excerpt :The latter is non-ergodic microheterogeneity, which takes place at the space scale of several dozens nanometers. It was established by measuring some physical values [1,2,4] such as viscosity, magnetic susceptibility, density, and also by neutron scattering [3,5]. The heterogeneity should be interpreted as a non-ergodic one, because its Gibbs probability is negligible due to large surface energy of dispersed heterogeneous state.
The hidden disintegration of cluster heterogeneity in Fe-based glass-forming alloy melt
2018, Progress in Natural Science: Materials InternationalRevealing a structural transition in typical Fe-based glass-forming alloy melts
2018, Journal of Non-Crystalline SolidsCitation Excerpt :It was accepted that the short-range order (SRO) of glass-forming melt changed slightly and can exist long-living with temperature because of the strong metal-metalloid bonds [6–10,20]. So these kinds of transformations characterized by the anomaly in the temperature dependence of viscosity, surface tension, crystallization temperatures, activation energies, and et al., should be only correlated to so-called “long-wave correlations”, “meso-scale heterogeneity” or “mesoscopic cluster” (Hereafter these are designed as large clusters) rather than the SROs [6–10,20]. After this transition, the melt structure turned to be uniform and stable.
