ORCHID

Version 1, machine-extracted: values were read by language-model readers constrained to quote their source and checked automatically, and the release was then audited on the printed pages by adversarial audits, an independent second review of fit-facing records and a preliminary human review of a frozen sample. Flags such as accepted and ESPEI-ready record screening results, not certification; known issues are listed in the release notes.

Every assessment. New angles.

Compare composition curves or trace one phase–quantity pair against another at fixed temperature. Every path is evaluated from a single eligible bundled database as composition changes.

Gex = xAxB Σ Lν(xA−xB)νDirectly evaluated from each archived TDB’s interaction parameters.

Explore the curves

Hover a curve to emphasize it and inspect its active parameters. Drag a rectangle across the plot to zoom; use Reset zoom to restore the full extent. Click without dragging to hide a curve and rescale.

Thermodynamic convention

Gmix and Smix include ideal configurational mixing plus the excess term. Hmix is Gex − T(∂Gex/∂T). Magnetic, ordered, ionic, interstitial, and multicomponent extrapolation terms are outside this view.
