Steel Phase & Transformation Explorer Interactive suite
Explore equilibrium phases, calculate lever-rule fractions, animate heat-treatment paths, compare steels, inspect generalized TTT/CCT behaviour, estimate chemistry-driven transformation temperatures and properties, practise with challenges, and export scenarios.
Plot and compare points
Select a row or marker. Drag a marker or tap the diagram to reposition the active point.
Phase analysis
Each point is evaluated independently.
Microstructure viewer
Schematic, not photomicrographic.
Final equilibrium microstructure
Room-temperature ferrite, pearlite, and proeutectoid cementite estimate.
Heat-treatment scenario builder
Create heating, holding, cooling, quenching, and tempering segments.
| Step | Target temperature | Duration | Mode |
|---|
Transformation timeline
Boundary crossings and expected metallurgical events.
Live phase state
Scrub the slider or play the cycle.
Animated microstructure
Tracks the current cycle temperature.
Generalized transformation kinetics
Switch between idealized TTT and CCT views. Curves shift heuristically with chemistry.
Predicted constituents
Educational kinetic estimate.
Critical temperatures
Calculated from the chemistry module.
Interpretation
Steel chemistry and grade presets
Enter wt% chemistry to estimate CE, Pcm, critical temperatures, hardenability, and property trends.
Weldability and transformation metrics
Estimated properties
Range estimates for the selected cooling rate.
Side-by-side steel comparison
Compares every plotted point using the same chemistry-driven estimates.
| Point | C | Temperature | Phase field | Equilibrium fractions | Final microstructure | Hardness trend | Weldability |
|---|
Phase-diagram challenge
Predict the phase field before revealing the answer.
Boundary guide
Click a boundary on the equilibrium diagram for the same information.
