Kaip apskaičiuoti Grain Size
Kas yra Grain Size?
Grain size affects mechanical properties: smaller grains = higher strength, higher hardness (Hall-Petch relationship).
Formulė
Calculate strengthening effect using Hall-Petch: σ = σ₀ + k/√d

Worked Examples
Įvestis
Grain size 1 μm vs. 100 μm
Rezultatas
1 μm ~ 50% stronger (Hall-Petch effect)
Common Mistakes to Avoid
- ✕Assuming smaller always better (sometimes reduces ductility)
- ✕Not accounting for material-specific k value
Frequently Asked Questions
How do you control grain size?
Cool rate (slower = larger grains), deformation (refines grains), annealing temperature.
