Which line on the above phase diagram corresponds to the Solid-Liquid transition? Answer
The lead and tin are partially dissolved in each other in solid state although they completely dissolved in liquid state. They form eutectic from solid solutions alfa (a) and beta (B) at alloying composition 62% tin and 38% lead, the eutectic forming temperature is 184°C. Alfa contained 20% tin dissolved in 80% lead at 184°C while beta consist of lead dissolved in tin at 184°C. If the 100 g of eutectic contained 45.5 g of alfa at 184°C.Knowing that the melting temperatures of lead and tin are 329°C and 232°C respectively, and the solubility of tin and lead in each other's diminished to zero at room temperature.
