Question

At what temperature, in the Fe-Fe3C diagram, does the peritectic region occur?

(a) 1400°C

(b) 1423°C

(c) 1492°C

(d) 1539°C

The question was asked by my school teacher while I was bunking the class.

My question comes from Air Requirements and Metallurgical Control for Cupola in division Metal Furnace and Practice of Casting-Forming-Welding II

Answer 1

Correct answer is (c) 1492°C

The best I can explain: In the iron – iron carbide diagram, or the Fe-Fe3C equilibrium diagram, the peritectic transformation occurs at a very high temperature. The temperature point of peritectic reaction takes place is 1492°C.
