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 have incomplete descriptions of their provenance.

The quality of the predictions in Thermo-Calc is strongly dependent on the quality of the databases because they provide the data for the calculations. This makes the databases as important, if not more so, than the software itself. 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 database

A combinatorial method of the diffusion couple, nanoindentation, electron probe microanalysis (EPMA), and CALculation of PHAse Diagrams (CALPHAD) techniques has been utilized to construct the Young's modulus database of Ti alloys with various compositions in the present work. 2007-10-18 2019-03-01 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 2 Database Overview TCHEA1 is a thermodynamic database developed espe-cially for high entropy alloys or multi-principal element alloys. It is developed in a CALPHAD spirit based on the critical evaluation of all the binary systems and many ternary systems. A hybrid approach of experiments, ﬁrst-principals calculations and CALPHAD modeling had Moreover, by means ofthe extrapolation of experimental data for the thermodynamicproperties of binary systems and high-pressure data for unaries,the metastable hcp phases at ambient pressure were modeledfor the third-generation CALPHAD database, consistently withother stable phases in the elements Fe and Mn. rium; quasi-equilibrium; multi-phase field method; CALPHAD database; nickel alloy 1.

Experimental Phase Equilibria, Thermodynamics and Kinetics. CALPHAD Applications in Materials Design, Advanced Manufacturing, Recycling, Disposal, For the isopleth section NiAl – 10Mo, the reconstructed phase diagram in Fig. 5 is compared with the originally derived phase diagram from the Calphad database. The enlargements I to III, depicted below the diagram, indicate a good correlation between the phase diagram of the Calphad data (black lines) and the reconstructed diagram of the fitted Gibbs energy functions (red marks). CALPHAD databases have traditionally been developed for investigation of single-principal component alloys.

It is developed in a CALPHAD spirit based on the critical evaluation of all the binary systems and many ternary systems. A hybrid approach of experiments, ﬁrst-principals calculations and CALPHAD modeling had CALPHAD stands for CALculation of PHAse Diagrams, a methodology introduced in 1970 by Larry Kaufman. An equilibrium phase diagram is usually a diagram with axes for temperature and composition of a chemical system. It shows the regions where substances or solutions (i.e. phases) are stable and regions where two or more of them coexist. 2020-03-21 · FactSage from CALPHAD Thermodynamic Database to Virtual Process Simulation IN-HO JUNG and MARIE-ALINE VAN ENDE The CALPHAD-type computational thermodynamic databases have been developed since 1970.
