### Left Diagram: Copper-Nickel Phase Diagram

This graph illustrates the phase diagram of a Copper-Nickel (Cu-Ni) alloy system. The x-axis represents the composition in weight percentage of Nickel (Ni), ranging from 0% to 100%. The y-axis displays temperature in degrees Celsius and degrees Fahrenheit, ranging from about 1000°C (1832°F) to 1455°C (2651°F).

- **Regions and Lines:**
  - **Liquid Region:** Above the "Liquidus line," where the alloy is fully liquid.
  - **Solidus Line:** Below this line, the alloy is completely solid.
  - **Mixed Phase Region (α + L):** Between the Liquidus and Solidus lines, where liquid and solid phases coexist.
  - **Eutectic Points:** At certain compositions and temperatures, marked with specific data points (e.g., the liquidus points at 1085°C and 1453°C).

### Right Diagram: Silver-Copper Phase Diagram

This graph depicts the phase diagram of a Silver-Copper (Ag-Cu) alloy system. The x-axis shows the composition in weight percentage of Silver (Ag), from 0% to 100%. The y-axis indicates temperature in degrees Fahrenheit and degrees Celsius, ranging approximately from 0°F (-18°C) to 2000°F (1093°C).

- **Regions and Phases:**
  - **Liquid Region:** Above the "Liquidus line," indicating the fully liquid state of the alloy.
  - **Solidus Line:** Below this line, the alloy is entirely solid.
  - **Mixed Regions:**
    - **(L + α) and (L + β):** Above the Solidus line, where liquid coexists with solid phases α and β respectively.
    - **(α + β):** Between α and β phases, indicating a solid solution of both phases.
  - **Eutectic Point (779°C/1435°F):** Specific composition and temperature where liquid transforms into two solid phases simultaneously.

These diagrams help in understanding the behavior and properties of metal alloys at different compositions and temperatures, crucial for materials science and engineering applications.
