Question
### Copper-Nickel Phase Diagram #### Graph Explanation The diagram presents a phase diagram for a copper-nickel alloy, illustrating temperature (in °C) against the weight percentage of nickel. It includes phases such as liquid, paramagnetic, and ferromagnetic. Key features of the graph include: - **Liquid Region:** Above the solid-liquid line, indicating complete liquidity regardless of the nickel percentage. - **Solid (α Phase):** Below the solid-liquid equilibrium line, indicating a single solid phase. - **Two-Phase (Liquid + α):** Between liquidus and solidus lines, indicating coexistence of liquid and solid. - **Curie Temperature Zone:** Indicates the transition from paramagnetic to ferromagnetic behavior in the alloy. #### Points of Interest: - **F, G, H, I, J:** Mark specific points within different regions or boundaries of the phase diagram for analysis. #### Tasks for Analysis: 1. **For Points F, G, H, I, and J, determine the following:** - **Temperature and phase of the material (liquid, solid or two-phase solid and liquid).** - **Percentage of solid and liquid.** 2. **Curie Temperature Analysis:** - At point C (100% Ni), the Curie temperature is 350°C. - At point D (68.5% Ni), the Curie temperature is 0°C. - Derive the equation of Curie temperature as a function of % Ni. 3. **Density Calculations:** - Calculate the Curie temperature and the density of the Cu-Ni alloy at 80% and 90% Ni using the density table from the previous lecture. This comprehensive phase diagram allows for a detailed analysis of the material properties and behavior under varying compositions and temperatures. Understanding these properties is crucial for applications requiring specific magnetic and structural characteristics.
