pycalphad is a free and open-source Python library for designing thermodynamic models, calculating phase diagrams and investigating phase equilibria within the CALPHAD method. It provides routines for reading Thermo-Calc TDB files and for solving the multi-component, multi-phase Gibbs energy minimization problem.

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.

Following Miedema’s method, the reference state Eref is defined as the average transition enthalpy of the two closed packed structures (fcc and hcp) plus the transition enthalpy of the bcc structure by the following equation. such as Calphad (calculation of phase diagrams), are employed to model thermodynamic properties for each phase and simulate multicomponent multi-phase behavior in complex systems. Written by recognized experts in the field, this is the first introductory guide to the Calphad method, providing a theoretical and practical approach. Building on core whose CALPHAD models allow binary models to be built, then ternary models and so on. This is also why there is research activity about very accurate calculations of the Gibbs energy and heat capacity of pure elements, to be compared with the CALPHAD unary database [10, 28].

In connection to developing the third generation of Calphad databases a new thermodynamic description is presented for unary carbon. Models used in this work have more physical basis and are valid down to 0 K. The anisotropy in graphite, caused by weak Van der Waals inter-plane forces makes it impossible to fit the heat capacity data by a single Einstein temperature for modelling the harmonic Ab initio-aided CALPHAD modeling is utilized to translate the electric current-induced effect into the excess Gibbs free energies of the phases. Hence, the phase equilibrium can be shifted by CALPHAD NaCl–KCl–ZnCl 2 ternary Thermodynamic modeling Molecular dynamics Enthalpies of mixing abstract The NaCl–KCl–ZnCl 2 ternary system is examined and modeled using the CALPHAD methodology in conjunction with molecular dynamics (MD) simulations. In particular, MD simulations are used for Calphad.

64 p. Research output: Thesis › Doctoral Thesis (compilation) CALPHAD (Computer Coupling of Phase Diagrams and Thermochemistry) aids the continous developments of alloy (and other materials) phase diagrams by the the creation of thermochemical databanks. The CALPHAD is solely based on the fact that a phase diagram is a manifestation of the equilibrium thermodynamics properties of the system, which are the sum of the properties of the individual phases.
