Summary: In this study, the growth velocity-related growth interface electromotive force (GEMF) is used to visualize interface instability and trace crystallization kinetics, predicting the upper and lower limits of critical growth velocity induced by constitutional supercooling and backmelting. A quantitative criterion for understanding and preventing critical interface instability is proposed based on GEMF. This method helps to understand ions migration and solidification under critical conditions, and can be used to optimize growth parameters and manipulate instability phenomena to fabricate unique microstructures.

Summary: We monitor the transformation of a liquid into an amorphous solid in simulations and find that the cooling rate has no significant influence on solidification when using potential energy as the order parameter. Instantaneous quenches accurately reproduce the solidification observed during slow cooling. The amorphous solidification is concluded to be an expression of the energy landscape topography.

Summary: Novel hydrothermal methods assisted by hydroxyapatite were used to solidify heavy metals in fly ash, resulting in hydrothermally-treated products that meet landfilling standards. The solidification mechanism involved the formation of stable compounds between hydroxyapatite and heavy metal ions. The addition of hydroxyapatite seed crystal improved the solidification efficiency.

Summary: The nature of ATP as amphiphilic and hydrotrope plays a role in maintaining solubility and preventing liquid-liquid phase separation of proteins, with ATP-MA1 static interaction driving phase separation. The attractive protein-protein interaction exclusively increased in the presence of ATP, altering protein surface properties and inducing LLPS of MA1. This ATP-induced LLPS was effectively eliminated by Mg2+ chelation with ATP to negate the static interaction.

Summary: The anisotropy of solid-liquid interface energy plays a fundamental role in dendritic morphology and pattern selection during solidification. Different dendritic morphologies are observed in Al-3 wt% Mg single crystals along different crystal orientations. A non-regular dendritic pattern selection map is constructed to explain the occurrence of different dendrites during alloy solidification.

Summary: This study investigates the formation mechanism of metastable solid phases in rapidly solidified eutectic systems. It proposes a diffusionless growth model to suppress eutectic decomposition and analyzes atomic diffusion in the growth of rod eutectics. A simplified calculating method for the Bessel function in the growth equation is also obtained, which can be applied to other rod eutectic growth models.

Summary: The freezing process of a water droplet on a cold substrate was experimentally investigated in this study. It was found that the spreading of the droplet stops due to the formation and growth of ice crystals which catch up with the advancing contact line. The study also showed that the thermal properties of the substrate play a major role in determining the frozen droplet radius.

Summary: Nonequilibrium thermodynamics and transportation kinetics near the propagating solid-liquid interface play a dominant role in the rapid solidification process. By using quantitative thermodynamic calculations of phase diagram and evaluating nonequilibrium effects in diffusion kinetics, a more precise description of rapid solidification process can be achieved.

Summary: It is proposed a general Ginzburg-Landau (GL) theory of solid-liquid interfaces to analyze the relation between lattice symmetry, the shape of the free-energy landscape, and surface energy anisotropy. The anisotropic form of the surface energy, depending on crystal symmetry, naturally appears in the perturbation expansion. The dependence of anisotropy on the free-energy landscape predicted by the perturbation scheme is shown to be in good agreement with numerical solutions of the GL theory.

Summary: The relationship between solidification mechanism and undercooling was systematically explored using electrostatic levitation technology. It was found that with increasing undercooling, the growth velocity of the TiNi alloy exhibited a complex pattern, with a sharp increase once the undercooling exceeded a critical value. The presence of the R-phase in the TiNi matrix at large undercooling suggested incomplete martensitic transformation.

Summary: Heterogeneous nucleation models in solidification have been developed over decades, divided into three categories: spherical cap nucleus model, free growth model, and constitutional supercooling model. These models exhibit uncertainty in describing the kinetics of heterogenous nucleation and are influenced by the crystal growth rate. It is crucial to approximate the solute flux at the solid-liquid interface for predicting grain size in practical applications.

Summary: This study investigates the fragmentation and solidification processes during the production of metal powders. The experiments reveal that fragmentation is controlled by capillarity, while solidification and viscosity have no influence. Additionally, the study finds that the circularity of the produced metal powder is size-dependent, with larger particles being less spherical.

Summary: The study investigated microstructure evolution and competitive grain growth in the spiral part of a single crystal sample with a crystal orientation deviating from the axial direction. It was found that stray grains in the spiral part compete with originally preferred orientation grains, leading to single-crystal orientation deviation defect. Stray grains tend to nucleate at the initial stage in the spiral part, and the inclined temperature gradient promotes their development.

Summary: The three-dimensional atom-probe tomography was used to characterize the interface structure of the gamma/gamma' in a third-generation Ni-based single crystal superalloy with Re addition, revealing an element-segregation layer with Re, Co, and Cr in the gamma phase close to the interface which resulted in a more negative local interface misfit. Additionally, it was deduced that the presence of harmful topologically close-packed phases might be facilitated by the co-segregation of Re, Co, and Cr, and the depletion of Ni near the interface.
