Using the following information: A binary system of A and B metallic elements, which are partially soluble in the solid state. . Consider linear solidus, liquidus, solvus lines. . The melting point of element A is 1000 C and the melting point of element B is 1250C. The system has a eutectic reaction which occurs at 750C, at a composition of CE: 25 wt% A. . The solid solution formed in A rich region a; the maximum solid solubility of B in a is 7%wt at eutectic temperature and drops to 3%wt at room temperature. The solid solution formed in B rich region is B; the maximum solid solubility of A in B is 5%wt at eutectic temperature and drops to 0%wt at room temperature. (a) Draw the phase diagram. Use a ruler and define the scale of temperature and composition axes properly. (b) Name all regions within the phase diagram. (C) We have an alloy with a composition of 50%wt A-50%wt B. Draw schematic of the expected microstructure at room temperature if the liquid alloy is slowly cooled down to room temperature. (d) Calculate the mass fractions of the two solids for the alloy with a composition of 50%wt A-50%wt B just below eutectic temperature. (e) Calculate the mass fractions of the two solids just below the eutectic temperature for the alloy having the eutectic composition
