Question
**Binary-Eutectic Alloy Phase Diagram** **Objective:** To draw a phase diagram for a binary-eutectic alloy given specific characteristics. **Characteristics:** - The melting temperature of component A is 1100°C. - The melting temperature of component B is 900°C. - The eutectic temperature of the alloy is 700°C. - The eutectic composition of the alloy is 60 wt% B. - The solubility limit of B in α at the eutectic temperature is 20 wt% B. - The solubility limit of A in β at the eutectic temperature is 10 wt% A. - At 0°C, no B is soluble in α and no A is soluble in β. **Instructions:** 1. Indicate the solvus, solidus, and liquidus lines. 2. Label the six phase fields: α, β, α + β, α + L, β + L, and L. **Graph Explanation:** The graph provided is a blank coordinate grid where the x-axis represents composition in weight percentage of component B (wt% B) ranging from 0 to 100 and the y-axis represents temperature in degrees Celsius (°C) ranging from 0 to 1200. - **X-axis (Composition, wt% B):** Range: 0 - 100 - Major ticks: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 - **Y-axis (Temperature, °C):** Range: 0 - 1200 - Major ticks: 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200 **How to Complete the Diagram:** 1. **Liquidus Line:** Starting from the melting point of pure A (1100°C at 0 wt% B), it slopes down to the eutectic point (700°C at 60 wt% B) and continues to the melting point of pure B (900°C at 100 wt% B). 2. **Solidus Line:** Starting at the eutectic point (700°C at 60 wt% B), one part slopes up to meet the solubility limit of B in α (700°C at 20 wt%
