We review major efforts thus far and we then provide a (brief) tutorial on basic concepts of uncertainty quantification and propagation (UQ/UP) in CALPHAD. We discuss the major features of frequentist and Bayesian interpretations of uncertainty and proceed with a discussion of recent case studies in which UQ has been used to parameterize models for the thermodynamic properties of phases.

ISBN This excellent book is probably the first comprehensive guide to the CALPHAD method.
Our databases are developed using the proven CALPHAD methodology, as shown in the graphic. The most time-consuming and critical steps in the process are the capture and assessment of data, which we devote tremendous resources and expertise to through in-house experts and international collaborations.

pycalphad is a free and open-source Python library for designing thermodynamic models, calculating phase diagrams and investigating phase equilibria within the CALPHAD method. We review major efforts thus far and we then provide a (brief) tutorial on basic concepts of uncertainty quantification and propagation (UQ/UP) in CALPHAD. We discuss the major features of frequentist and Bayesian interpretations of uncertainty and proceed with a discussion of recent case studies in which UQ has been used to parameterize models for the thermodynamic properties of phases. CALPHAD (Calculation of Phase Diagrams) is one of the most powerful techniques for Materials Genome and Integrated Computational Materials Engineering (ICME) modeling. The development of the CALPHAD-based method has taken place so quickly that it is not described adequately in conventional textbooks, nor is it covered properly in the majority of existing undergraduate or graduate degree 2020-08-03 · The CALPHAD-type computational thermodynamic databases have been developed since 1970. Several commercial computational thermodynamic software equipped with comprehensive and accurate thermodynamic databases and fast Gibbs energy minimization routine are widely used in the design of new materials and the optimization of materials processing. 2021-04-24 · Alloy Theoretic Automated Toolkit (ATAT) Home Page.
