Phase Diagram Compilations

Search periodic table for Phase Diagram information

MSI Eureka has compiled a comprehensive overview of the past publications and phase diagrams and it continues to monitor current and future publications.

The phase diagram compilations: Diagrams as Published and Research Results are accessed via the periodic table of the interface & viewing software Eureka Viewer or in the browser interface at

Diagrams as Published

Phase Diagrams as Published Results
Reference Diagrams as Published: Carbon-Titanium (C-Ti) binary system
Reference Diagrams as Published: Boron-Nickel-Silicon (B-Ni-Si) ternary system

"Diagrams as Published" are binary and ternary phase diagrams as published in the literature. They are collected from literature, uniformly edited by MSI, supplemented with crystallographic data of the phases from reference handbooks. They are not critically evaluated by MSIT.

Currently the category "Diagrams as Published"  includes over 2040 ternary and binary diagrams, as of Dec. 2022).

Research Results

Phase Diagram Research Results
Phase Diagram Research Results: Boron-Iron-Neodymium (B-Fe-Nd) ternary system

Documents in the category "Research Results" are extended extracts from the literature or original short publications made by individual authors - all sorted after materials systems.

Each document under "Research Results" reports data on one materials system only. Therefore one journal article may have generated several entries under Research Results, one for each element combination reported in the paper.

All information is presented as published, i.e. not assessed in the light of other data known, contrary to the binary and ternary MSIT Evaluation Reports.
