The construction of phase diagram calculations based on experiments and thermodynamic analysis are generally referred to as the calculation of phase diagrams (CALPHAD) approach [ 20.1 ]. This method provides a very accurate understanding of the properties originating in the macroscopic character of the material under study. It is widely reported that CALPHAD is an extrapolation method when the thermodynamic properties of a multicomponent system are approximated by its subsystems. In this work the meaning of the words extrapolation and interpolation is discussed in context of the CALPHAD method.

•Early predecessors – van Laar 1908 and later several others. microstructural modeling. Here is given an introduction to the CALPHAD method [19, 27], explaining how it actually models the thermodynamic properties of multicomponent systems. Then, a number of applications are described, while emphasizing the relevance of using the CALPHAD method for the purpose of developing integrated engineering methods. The CALPHAD Method The Monograph on the Calculation of Phase Diagrams (CALPHAD), authored by staff at Sente Software, may be consulted for background information at any desired level.

As the thermodynamic functions of a phase are related through their definitions, it is the usual practice in the CALPHAD approach to find expressions for the Gibbs

Thermal vacancies in solids have not been treated explicitly in the CALPHAD-type thermodynamic assessments because it was considered that their contributions to the Gibbs energy were limited, even at the melting point. However, the vacancy fraction is necessary for dynamic simulations, such as precipitations and diffusion processes. Written by recognized experts in the field, this is an introductory guide to the CALPHAD method, providing a theoretical and practical approach.

CALPHAD method attractive for the prediction of materials properties [10] and the coup-ling with materials simulation codes, such as solidification simulations [11] or phase field simulations [12]. With this ability to describe multicomponent materials properties as functions of composition and temperature, CALPHAD-based approaches have served as
