Question

1. In a tabular form, what is the difference between a Eutectic and a Eutectoid reaction?

2. What are the metastable phases?

3.Lead melts at 620 ° F (327 ° C), and tin melts at 450 ° F (232 ° C), both form a eutectic containing 62% tin at 360 ° F (182 ° C), the maximum solid solubility of tin in lead at this temperature is 19%; and lead in tin is 3%. Suppose that the solubility of each at room temperature is 1%.

a.- Draw the equilibrium diagram and mark all the points, lines and areas.

b.- Describe the solidification of a 40% tin alloy. Sketch its microstructure at room temperature, giving the chemical composition and the relative amounts of the phases present.

c.- Draw the cooling curve for the above alloy.

d.- Repeat exercises b and c for an alloy containing 90% tin.

 

4. Determine the chemical composition of the ternary alloys indicated as “Y” and “Z” in the attached Gibbs triangle:
