Heat treatment (annealing, quenching, tempering) modifies crystal structure and properties through controlled heating/cooling.
ଷ୍ଟେପ୍-ଷ୍ଟେପ୍ ଗାଇଡ୍ |
- 1Input initial material state and desired properties
- 2Specify heat treatment: temp, time, cooling rate
- 3Predict resulting microstructure and properties
ସମାଧାନ ହୋଇଥିବା ଉଦାହରଣ
ଇନପୁଟ୍
Steel: quench from 850°C (high hardness) vs. anneal (low hardness, high ductility)
ଫଳ
Tempering balances hardness and ductility
ଏଡ଼ାଇବା ଯୋଗ୍ୟ ସାଧାରଣ ଭୁଲ
- ✕Wrong temperature for material type
- ✕Not controlling cooling rate sufficiently
ବାରମ୍ବାର ଜିଜ୍ଞାସା
Why cool fast (quench)?
Rapid cooling prevents atomic rearrangement to equilibrium, creating harder metastable phases.
