Phase Diagrams Lead-tin solder is commonly used for electrical connections due to its low melting point and electrical conductivity. Answer the following questions regarding the Pb-Sn phase diagram shown below: 1. What is the eutectic composition (wt%) and temperature? 2. What is the maximum solubility of tin in solid lead (wt%) and at what temperature does it occur? 3. Calculate the equivalent solubility in atomic %. 5. What is the solubility of lead in solid tin at the eutectic temperature? 6. Explain the sequence of events in terms of phase transitions, cooling rate, and microstructure development for a 30 wt% tin alloy cooling from 300°C to 100°C in room temperature air.
