# Au–Zn phases > Au–Zn system: 15 phases (tier A 5, tier B 1, tier C 3, liquid 1, needs_review 5); 14 stable in a calculated diagram in the ORCHID phase registry, with names, structure type when the stored evidence supports an assignment under the stated tier rules, calculated stability, verbatim TDB PHASE/CONSTITUENT statements and example references. HTML: https://data.orchid-project.org/phases/pages/AU-ZN.html · Markdown: https://data.orchid-project.org/phases/pages/AU-ZN.md 15 phases (tier A 5, tier B 1, tier C 3, liquid 1, needs_review 5); 14 stable in a calculated diagram. Structure types are assigned only when the stored evidence supports an assignment under the stated tier rules (tier A: standard phase name; tier B: unique Materials Project + OQMD on-hull match, DFT-supported; tier C: one structure stated by the assessment's crystallographic table, assessor-stated); other phases list candidates and are marked needs_review. Stability is from phase diagrams calculated with pycalphad from the SGTE binary collection (evidence class: model).
