Heat treatment (annealing, quenching, tempering) modifies crystal structure and properties through controlled heating/cooling.
단계별 가이드
- 1Input initial material state and desired properties
- 2Specify heat treatment: temp, time, cooling rate
- 3Predict resulting microstructure and properties
풀어진 예시
입력
Steel: quench from 850°C (high hardness) vs. anneal (low hardness, high ductility)
결과
Tempering balances hardness and ductility
피해야 할 일반적인 실수
- ✕Wrong temperature for material type
- ✕Not controlling cooling rate sufficiently
자주 묻는 질문
Why cool fast (quench)?
Rapid cooling prevents atomic rearrangement to equilibrium, creating harder metastable phases.
