1. Explain the difference
between ‘eutectic’ and ‘eutectoid’.
2. Explain the terms
‘hyper-‐ and hypoeutectoin ’and
‘hyper-‐ and hypoeutectic
Considering iron-iron cementite phase diagram eutectic reaction occurs at 4.3%c where liquid decomposes slowly to form Austenite and cementite
while on the other hand Eutectoid reaction occurs at 2.14%c where Austenite decomposes to form ferrite and cementite and this occurs at 723degee celcious.
