Q1. 1.What are the phases represented in the iron-carbon phase diagram? 2. What is the difference between annealing and normalizing processes?
Ans. 
The iron-carbon phase diagram illustrates phases like ferrite, cementite, and austenite, while annealing and normalizing are heat treatment processes.
• Phases in the iron-carbon diagram include: Ferrite (α), Cementite (Fe3C), Austenite (γ), and Pearlite.

• Ferrite is a soft phase with low carbon content, while cementite is hard and brittle.

• Austenite is a high-temperature phase that can transform into other phases upon cooli...read more
