Heat Treatment ची गणना कशी करावी
Heat Treatment म्हणजे काय?
Heat treatment (annealing, quenching, tempering) modifies crystal structure and properties through controlled heating/cooling.
चरण-दर-चरण मार्गदर्शक
- 1Input initial material state and desired properties
- 2Specify heat treatment: temp, time, cooling rate
- 3Predict resulting microstructure and properties
Worked Examples
इनपुट
Steel: quench from 850°C (high hardness) vs. anneal (low hardness, high ductility)
परिणाम
Tempering balances hardness and ductility
Common Mistakes to Avoid
- ✕Wrong temperature for material type
- ✕Not controlling cooling rate sufficiently
Frequently Asked Questions
Why cool fast (quench)?
Rapid cooling prevents atomic rearrangement to equilibrium, creating harder metastable phases.
