All thermodynamic databases are developed following the Calphad methodology. The term Calphad stems from Calculation of Phase Diagrams, which has been the origin of the development of our thermodynamic databases – but today our users do much more than simply calculating phase diagrams, from calculation of a single complex equilibrium to viscosities. CALPHAD (CALculation of PHAse Diagrams) denotes the methodology used to assess thermodynamic data based on experiments as well as on first principles calculations. Essential for this method is the coupling of phase diagram and thermodynamic CALPHAD Applications in Materials Development, Processing and ICME. CALPHAD Applications for a Sustainable World.

It is a search engine for thermodynamic data available in TDB format. Such files can be read by most thermodynamic modeling software (Thermocalc, Pandat, Open Calphad, etc.). This site provides links to the data files and acticles rather than data/article itself (for copyright and fairness Based on the experimental and/or theoretical data, CALPHAD (CALculation of Phase Diagrams) approach is adopted to establish the Young's modulus database and then to predict the Young's moduli as a function of composition [ [21], [22], [23], [24], [25] ]. 2020-11-28 These CALPHAD databases rely on both experimental and computational phase-based data including, thermodynamic, diffusion, molar volume, elastic property, electrical conductivity, or thermal conductivity data. These data are diverse, semi-structured and often … Calphad databases. All thermodynamic databases are developed following the Calphad methodology.

Computational Phase Diagram Database (CPDDB) On Computational Phase Diagram Database, the Gibbs energy functions of the phases are accumulated in a form of TDB (Thermodynamic DataBase) files, which are obtained from the CALPHAD-type thermodynamic assessments.

For 2.1 and 2.2: By inputting the parameters into the software, Computational Thermodynamics: The Calphad Method: Sundman, Bo (Royal assessment methodology, optimization tools, and thermodynamic databases.

CALPHAD methodology consists of four main steps for developing databases of materials systems: i) collecting the available experimental data on the to-be-modeled properties, for example, in the case of thermodynamics these would be the data on phase equilibria, crystal structure, and thermochemical data, ii) critical assessment of the captured data and choosing the appropriate model based on this data, iii) optimizing the free parameters of the models and iv) appending the optimized model

If you've ever wondered how we develop our thermodynamic and properties database, this video is for you. Thermo-Calc Software databases are developed

Thermo-Calc Software has long experience in the field of database generation using the proven CALPHAD methodology. We employ a highly qualified team of people working on database development internally and through international collaboration projects. CALPHAD Assessments and Database Development. Modeling of Diffusion and Phase Transformations. Software Development. Experimental Phase Equilibria, Thermodynamics and Kinetics. CALPHAD Applications in Materials Design, Advanced Manufacturing, Recycling, Disposal, CALPHAD Applications in industrial processes (energy production, joining and soldering, ) OpenCalphad (OC) is an informal international collaboration of scientists and researchers interested in the development of high quality software and databases for thermodynamic calculations using the CALPHAD (CALculation of PHAse Diagrams) method.The OC project was initiated by Suzana G. Fries as part of the Sapiens project at ICAMS (International Center for Advanced Materials Simulations) at Ruhr University, Bochum, Germany.

CALPHAD is a proven methodology for predicting thermodynamic, kinetic, and other properties of multicomponent material systems. At Thermo-Calc Software, we use CALPHAD methodology to develop our databases, which, when used together with our software, can predict the properties of multicomponent systems corresponding to real materials.
