At What Temperature Does Peritectic Reaction Occur?

Peritectic temperature 1495°C (2723°F). Austenite (γ) phase (fcc) with carbon in interstitial solid solution. Because the outcome of the reaction is not shown in the final microstructure of carbon and low alloy steels, little attention is paid to the peritectic reaction in solidification stages.

What is peritectic temperature?

At the peritectic temperature (1580^o) all of the remaining liquid will react with all of the previously precipitated Fo to produce crystals of En. The temperature will remain constant until this reaction has gone to completion, after which the only phase present will be pure En.

At what temperature does peritectic reaction occur in the iron carbon binary system?

Peritectic Reaction • Peritectic reaction: at 0.16% C and 14930 C δ(0.11% C) + L(0.51%C) ↔ γ (0.16%C) • In peritectic reaction, the liquid and δ iron transforms into austenite (containing 0.16% C). The peritectic reaction occurs at a constant temperature. This is known as peritectic temperature and is 1493°C.
