    Morphological stability of growing particles and maximum growth rate principle (1992)

    Notes: The maximum growth rate (MGR) principle is discussed in connection with the morphological stability of growing particles. It is suggested that the MGR principle may be applicable to the growth of a platelike particle when there is no sidebranching. The suggestion is based on a stability analysis indicating that MGR principle would hold at least approximately unless the supersaturation is too large. For large supercooling, the stability analysis breaks down, but the MGR principle still presents reasonable values.

    On the applicability of the Ivantsov growth equation (1997)

    Notes: The steady state growth equation for a paraboloid of revolution and a parabolic cylinder, taking the interfacial energy into account, is revisited. Although the consideration of the interfacial energy was necessary, the growth equation was much more complicated than the original equation with a zero interfacial energy, since both the thermodynamics and kinetics of the growth are considered in one equation. In the present work, we take advantage of the development in computational thermodynamics and consider the thermodynamics and kinetics of the process in separate equations, but solve them simultaneously. A consistent framework to describe the phenomena and compare it with previous treatment of the interfacial energy will be presented. © 1997 American Institute of Physics.

    Thermodynamics of the Mg–B system: Implications for the deposition of MgB2 thin films (2001)

    Notes: We have studied the thermodynamics of the Mg–B system with the calculation of phase diagrams modeling technique using a computerized optimization procedure. Temperature–composition, pressure–composition, and pressure–temperature phase diagrams under different conditions are obtained. The results provide helpful insights into appropriate processing conditions for thin films of the superconducting phase, MgB2, including the identification of the pressure–temperature region for adsorption-controlled growth. Due to the high volatility of Mg, MgB2 is thermodynamically stable only under fairly high-Mg overpressures for likely growth temperatures. This places severe temperature constraints on deposition techniques employing high-vacuum conditions. © 2001 American Institute of Physics.

    Thermodynamic Modeling of the YO1.5–ZrO2 System (2004)

    Notes: The YO1.5–ZrO2 system consists of five solid solutions, one liquid solution, and one intermediate compound. A thermodynamic description of this system is developed, which allows calculation of the phase diagram and thermodynamic properties. Two different solution models are used—a neutral species model with YO1.5 and ZrO2 as the components and a charged species model with Y3+, Zr4+, O2−, and vacancies as components. For each model, regular and subregular solution parameters are derived from selected phase equilibrium and thermodynamic data. The neutral species and charged species modeling results are compared.

    Notes: The phase equilibria and thermodynamic properties of the binary Ba–O system were analyzed. The Gibbs energy functions of individual phases were modeled, and the model parameters were obtained by means of the CALculation of PHAse Diagram (CALPHAD) technique, based on available experimental data in the literature. The liquid phase was described with a two-sublattice ionic model. For the non-stoichiometric BaO and BaO2 phases, a two-sublattice ionic model was applied, and two sets of Gibbs energy functions were obtained by treating them either as separate phases or as a common solution phase with a miscibility gap. The ionic sublattice models used in the present work provide an approach to better describe the physical behavior of the Ba–O binary system such as defect chemistry and doping effects, which will be studied in multicomponent systems.

    First-Principles Investigation of Laves Phases in Mg-Al-Ca System (2005)

    Notes: Recent experiments and first-principles calculations in the literature revealed the existence of a C36 laves phase in the Al2Ca-Mg2Ca pseudo-binary system in addition to the C14-Mg2Ca and C15-Al2Ca laves phases. In the present work, special quasirandom structures (SQS) for all three laves phases were constructed. The structures possess local pair and multisite correlation functionsthat mimic those of the corresponding random structures. First-principles calculations were carried out based on the SQS developed to predict the enthalpy of formation in the Al2Ca-Mg2Ca pseudo-binary system. It was observed that the enthalpy of formation of C36 is very close to that of C14 at the Mg2Ca end and decreases with the addition of small amount of Al, while the enthalpy of formation of C14 increases with the addition of Al. It is thus energetically plausible that C36 isstable in the Al2C- Mg2Ca pseudo-binary system
