A brief history of CALPHAD

Calphad: Computer Coupling of Phase Diagrams and Thermochemistry, 2008
Abstract Some 35 years ago, Larry Kaufman and Himo Ansara provided the stimulus to bring together a small number of scientists who were working on the calculation of alloy phase diagrams using as basis the required consistency of experimental thermodynamic and phase boundary data.

A thermodynamic assessment of the binary Fe-Mn system for the third generation of Calphad databases

open access: yesCalphad: Computer Coupling of Phase Diagrams and Thermochemistry, 2019
In developing the third generation of Calphad databases, the next step after proper description of the unaries is to assess higher-order systems, i.e. binaries, ternaries etc.

An insight into using DFT data for Calphad modeling of solid phases in the third generation of Calphad databases, a case study for Al [PDF]

open access: yesCalphad: Computer Coupling of Phase Diagrams and Thermochemistry, 2019
In developing the next generation of Calphad databases, new models are used in which each term contributing to the Gibbs energy has a physical meaning.

The CALPHAD Method

2006
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 (Sect. 1.3).

Nano-Calphad: extension of the Calphad method to systems with nano-phases and complexions

Journal of Materials Science, 2012
The abbreviation “nano-Calphad” stands for “Calculation of Phase Diagrams for nano-systems.” Nano-systems contain at least one phase or at least one interface layer (film, complexion) with at least one of its dimensions being below 100 nm. The essential task of nano-Calphad is to introduce correctly the surface term into the equation for the Gibbs ...

Calphad

2019
Modern thermodynamic assessment studies of multicomponent systems typically employ the Compound Energy Formalism (CEF) to describe phases of variable composition, which may show effects of chemical ordering. In CEF, the ordering is described by splitting a crystallographic site in which several components can substitute for each other into subsites ...
