Get the A1, A3 and Acm transformation temperatures of the Fe-Fe3C phase diagram for a given carbon content, with the sourced curve model shown (Andrews 1965 sqrt-of-carbon A3 shape normalized to the diagram's fixed points; Acm interpolated over published anchor points — sources and anchor tables included in the response, not a black box). Use for questions like "at what temperature does 0.3% carbon steel become fully austenitic" or "what is the A3 temperature of C45". Omit the carbon parameter to get the fixed points (G, S, E) and full curve model.

Get a structured glossary of steel phases, microstructure constituents and related terms (ferrite, austenite, cementite, pearlite, bainite, martensite and more), each explained at three levels: simple, technical and scientific. English, Slovak and Czech. Use when explaining metallurgy concepts at an audience-appropriate depth.

Interpret what forms when eutectoid plain-carbon steel (~0.76 wt% C) is cooled at a constant rate to room temperature: fractions of pearlite, bainite, martensite and retained austenite, via Scheil additivity over a published TTT dataset and Koistinen-Marburger martensite kinetics. Accepts an explicit cooling rate (0.005-2000 C/s) or a named quench preset: furnace, air, oil, or water. Use for questions like "what happens if I quench eutectoid steel in oil", "how fast must steel cool to become fully martensitic", or "will air cooling give pearlite". Educational tier, eutectoid composition only; every response carries the assumed process history, assumptions, refusals (including section-size effects and other compositions) and verification needs.

Interpret an isothermal hold (TTT / austempering-style treatment) of eutectoid plain-carbon steel: quench to a hold temperature, hold for a given time, then quench to room temperature. Returns transformation start/finish times at that temperature, the JMAK transformed fraction, and product fractions (coarse/fine pearlite, upper/lower bainite, martensite, retained austenite) at the hold and after final quench. Use for questions like "what forms if steel is held at 350 C for 100 seconds" or "how long until transformation finishes at 600 C". Educational tier, eutectoid composition only, with explicit process history, assumptions, refusals and verification needs.

Interpret the equilibrium state of plain-carbon steel at a given carbon content and temperature: stable phases, microstructure constituents (pearlite, proeutectoid ferrite or cementite), lever-rule phase mass fractions, qualitative mechanical property tendencies and typical applications. Use for questions like "what phases does 0.45% carbon steel have at 700 C", "what is the microstructure of slowly cooled eutectoid steel", or "why is high-carbon steel brittle". Educational equilibrium model (Fe-Fe3C, 0-2.14 wt% C, 20-1147 C) with explicit assumptions, refusal boundaries and verification needs in every response. Does NOT predict quenching or cooling-rate effects — use interpret_continuous_cooling or interpret_isothermal_hold for that.

Look up MEASURED (not modeled) steel datasets transcribed from published sources, each with full citation, license, ready-made attribution string and extraction provenance down to the table or figure of origin. Covers dilatometric CCT hardness data for named steel heats, continuous-cooling phase fractions, isothermal/parametric cooling kinetics, and historical digitized TTT data (including the founding 1930 Davenport & Bain eutectoid dataset) — sources are CC-BY or public domain. Use when the user needs real measured hardness or transformation values with a citable source rather than a model estimate — e.g. "what measured hardness does S960MC reach at 30 C/s". Call without arguments for the current list of available datasets (the list grows over time); pass dataset_id for full records.
