fasediagrammer

Fasediagrammer is a software application designed for the visualization and analysis of phase diagrams in materials science, chemistry, and related disciplines. It provides tools to construct phase stability maps from thermodynamic data and to explore how phases change with temperature, composition, and pressure.

Its core capabilities include support for binary and ternary diagrams, a range of plotting styles, and interactive exploration of phase boundaries. The program integrates with thermodynamic databases and allows users to import custom data. Calculations based on Gibbs free energy minimization, lever rule, and tie-line construction are available to determine phase fractions and stability limits. Diagrams can be rendered in 2D or 3D, annotated with critical points, invariant reactions, and miscibility gaps.

Users build projects by importing data, defining components, and selecting calculation methods. The interface emphasizes live updates so that adjusting composition or temperature immediately refreshes the diagram and computed phase fractions. Output options include vector or raster images, export of data tables, and scripting for batch processing.

Fasediagrammer is developed and maintained by an international community of researchers and developers. Releases are published on the official project site and are designed to be extensible through plugins or scripting.

The tool is used in academic research, alloy development, and education to visualize complex phase relationships, compare thermodynamic models, and illustrate phase equilibria for teaching purposes.
