Could someone explain in detail how to solve this problem please. I really dont understand it. Thank you so much.

**Understanding the Fe-C Phase Diagram** **Introduction:** The Fe-C (Iron-Carbon) phase diagram is a crucial tool for understanding the phases and reactions in iron-carbon alloys, which include steel and cast iron. It maps out the phases present at different temperatures and carbon compositions. **Description:** The diagram provides a graphical representation of temperature vs. composition (in wt% C for the lower x-axis and at% C for the upper x-axis). The y-axis displays the temperature in both Celsius (°C) and Fahrenheit (°F). **Key Regions and Points on the Diagram:** 1. **Region A (Ferrite, α)** - Composition: Up to approximately 0.025 wt% C. - Phase: Ferrite (α) is a body-centered cubic (BCC) phase. - Temperature Range: Room temperature to the A1 line (approximately 912°C or 1674°F). 2. **Region B (Austenite, γ)** - Composition: From about 0.025 wt% C to 2.1 wt% C. - Phase: Austenite (γ) is a face-centered cubic (FCC) phase. - Temperature Range: Between the A1 line (727°C) and 1147°C. 3. **Region C (Cementite, Fe₃C)** - Composition: Fixed at 6.67 wt% C. - Phase: Cementite (Fe₃C) is an iron carbide compound. - Temperature Range: Exists below the 1147°C line. 4. **Region D (Liquid)** - Composition: Varies within the entire range of the diagram. - Phase: Molten metal. - Temperature Range: Above 1153°C, indicating the melting points of mixtures. 5. **Region E** - Composition: Approximately 4.2 wt% C. - Temperature: At about 1153°C. - Phases: Transition between liquid and solid solutions. 6. **Region F** - Composition: Around 0.65 wt% C. - Temperature: Approximately 740°C. - Phase: Transition of austenite to pearlite and ferrite. **Specific Points on the Diagram:** - **Point D (1153°C, 2.1 wt% C)** - Phases: Liquid and austenite. -
