Q2 Answer one of the following. (20 marks) A) Draw the phase diagram for 2 metals (A, B) with melting points (500°C, 600°C respectively). They are completely insoluble in each other in solid stale. They form a fully eutectic alloy at 250° with 60% B metal. 1- find the chemicals composition of liquid and solid at 300°C for alloy with 30% B. 2- draw the expected microstructure for alloy 30% B 3-find the melting range of alloy with 80% B (start of solidification, end of solidification). B) Estimate the theoretical density of Lead with the following information. Crystal structure FCC. Atomic Radius 0.175 nm. Atomic weight 207.2 g/mol. Show the mathematical steps in details.
