Non-Stoichiometry and Calphad Modeling of Frank-Kasper Phases
One of the many singularities of Frank-Kasper phases is their ability to accommodate extremely large composition ranges by atom mixing on the different sites of the crystal structures. This phenomenon will be reviewed in the present paper with special emphasis on the experimental demonstration of this phenomenon, the theoretical calculation of disordered structures and the modeling of these pha...
متن کاملDensity Functional Theory-Based Database Development and CALPHAD Automation
We report our research activities on density functional theory-based alloy thermodynamics, including method/software developments, the integration of first-principles calculations, CALPHAD modeling, and the automation of phase diagram calculations. Examples to be discussed include phonon dispersions of rhombohedral BiFeO3, the solution to the long-outstanding problem of imaginary phonon frequen...
متن کاملProgress of Membrane Engineering for Water Treatment
Together with the supply of energy and the environmental protection, fresh water is one of the three keys elements for the sustainable development of every society. Where the availability of water cannot be carried out by using conventional sources, unavoidable appears the resort of the major water source: the sea. Today, RO is one the most used membrane processes for the production of fresh wa...
متن کاملPhase-field Modeling with CALPHAD and CVM for Microstructural Evolution of Ni-base Superalloy
To perform a quantitative simulation using the Phase Field Method (PFM) in a real alloy system, a new strategy of modeling the microstructure evolution of Ni-base superalloy is proposed in the present paper. In this strategy, the Calculation Phase Diagram (CALPHAD) method and Cluster Variation Method (CVM) are combined with the PFM, in which the four sub-lattice model is used to evaluate the fr...
متن کاملAb initio-aided CALPHAD thermodynamic modeling of the Sn-Pb binary system under current stressing
Soldering is an ancient process, having been developed 5000 years ago. It remains a crucial process with many modern applications. In electronic devices, electric currents pass through solder joints. A new physical phenomenon--the supersaturation of solders under high electric currents--has recently been observed. It involves (1) un-expected supersaturation of the solder matrix phase, and (2) t...
