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. (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
