Follow a coupon through a radiant furnace, a short austenitizing hold and a quench. A magnified microstructure inset changes as diffusion competes with martensitic transformation.
• 3D scene parts: radiant furnace and heating elements; coupon and transfer tongs; quench tank and circulation; magnified microstructure; temperature and hardness indicators. • Controls: furnace setpoint (760–900 °C), hold duration (1–8 model s), quench time constant (1–40 model s). • Live readouts: coupon temperature; untransformed austenite; diffusional product; martensite; un-austenitized base; illustrative mixture hardness. • Guided experiments: Fast quench; Slow cooling; Insufficient heating. • Four tabs (visual laboratory, curves and measurements, experiments, learn and assess), a model-verification run, a timestamped event log and a trial report.
Heating: 25 → setpoint in 8 model s; then hold Austenitized fraction=min(hold/3,1) only if setpoint ≥820 °C Quench: T=25+(Tpeak−25)exp(−tq/τ) Diffusion hazard: 0.3 exp[−((T−550)/70)²] /s, only 400<T<700 Below Ms=350: fM=fA,remaining[1−exp(−0.011(350−T))] Hardness weights: base 220, diffusive 220, austenite 180, martensite 720 HV.
A deliberately synthetic steel-like transformation model with declared thresholds and kinetic constants. It illustrates competing transformation paths, not a real alloy CCT chart, tempering schedule, distortion or crack prediction. The short hold and cooling times are model time. Mixture hardness is a teaching estimate. Try the preset experiments, then compare the live readouts with the equations.
No. The modeled transformation requires an austenitic starting fraction.
No. The model uses illustrative mixture weights and synthetic kinetics.
