If LaTeX is used, please follow the style sheets provided in the link below. Manuscript Preparation Pre-submission. 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.

Phase diagrams offer various areas of materials science and technology indispensable information for the comprehension of the properties of materials. The microstructure of solid materials is generally classified according to the size of the constituents - for example, at the electron, atomic, or granular level (see Chap. 3). Accordingly, fundamental principles like quantum mechanics

dynamics simulations, Monte Carlo simulations, CALPHAD modeling (acronym of Calculation of CALPHAD method quantitatively models the Gibbs energy.

The method is based on semi-empirical approach, and therefore reliable experimental data are necessary for description of thermodynamic and phase properties of unary and binary systems. CALPHAD (Computer Coupling of Phase Diagrams and Thermochemistry) aims to promote computational thermodynamics through development of models to represent thermodynamic properties for various phases which permit prediction of properties of multicomponent systems from those of binary and ternary subsystems, critical assessment of data and their incorporation into self-consistent databases, development of software to optimize and derive thermodynamic parameters and the development and use of The CALPHAD method Webinar 2016-11-15.

The CALPHAD method, on the other hand, is based on the minimization of the free energy of the system and is, thus, not only completely general and extensible, but also theoretically meaningful. The experimental determination of phase diagrams is a time consuming and costly task. This becomes even more pronounced as the number of components
