Diffusion coefficient (D) describes rate at which atoms/molecules move through material; temperature-dependent (Arrhenius).
सूत्र
Calculate D = D₀ exp(-Ea/kT)
- D
- D₀ exp(-Ea/kT) — D₀ exp(-Ea/kT)
- Ea
- Ea value — Variable used in the calculation
चरण-दर-चरण मार्गदर्शिका

इनपुट
Carbon in steel at 800°C
परिणाम
D ≈ 10⁻¹² m²/s (extremely slow at room temp, faster when hot)
सामान्य गलतियां जिनसे बचना है
- ✕Using wrong temperature (K not °C)
- ✕Neglecting Arrhenius relationship
अक्सर पूछे जाने वाले प्रश्न
Why is diffusion important?
Controls carburizing, doping, sintering, creep; essential for heat-treatment design.
