Materials Science International (MSI) Phase Diagrams - High-Quality Evaluated Phase Diagrams in MedeA

msieurekalogo [1] is the world’s leading and most comprehensive database for critically evaluated phase diagrams and related materials property data for metals, alloys, non-metals, and composites. Integration with MedeA®[2] makes MSI Phase Diagrams an indispensable resource for materials science and engineering.


MSI Phase Diagrams offers phase diagrams, thermodynamic properties, and crystallographic data, critically evaluated and reviewed by experts of the Materials Science International Team (MSIT)®. The MSI Phase Diagrams module greatly enhances MedeA’s modeling capabilities for materials discovery, design, and optimization projects.

Key Benefits

  • Build modeling strategies on expertly validated thermodynamic data
  • Swift access to full-text documents and critical evaluation reports
  • Seamless integration with MedeA

MSI Phase Diagrams provides critical intellectual evaluations of all data on constitutional properties, phase equilibria, thermodynamic and crystallographic data. Critical evaluation includes the resolution of contradictory published results, comparing and analyzing conclusions, and interpreting results based on assessing all available knowledge. (MSIT)® evaluation reports discuss and remedy conflicting data and rationalize the choice of the most appropriate data sets. The evaluation reports are authentic publications, peer reviewed under the auspices of the (MSIT)® editorial board. Reliable phase diagrams provide scientists and engineers with basic information of crucial importance for fundamental research and for the development and optimization of materials. The evaluation reports are an ideal source for computer-aided modeling and simulations, and are a repository of reliable validated data.


  • Provides over 4,380 critically evaluated reports for ternary and binary inorganic systems
  • Altogether, more than 12,600 phase diagrams, graphs, charts, and schemes
  • Approximately 8,600 tables with crystallographic data, invariant reactions, materials properties, experimental details, thermodynamic properties, etc.
  • Data are obtained from 70,000 and more peer-reviewed original publications
  • Around 2,000 additional phase diagrams in the category “Diagrams as published”, which are not evaluated by the MSIT®.

Key Features

  • Full integration with MedeA provides efficient and flexible database search capabilities
  • Quick, efficient retrieval of full-text documents and phase diagrams using an intuitive, menu-based query language
