Question
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 1250°C.
• The system has a eutectic reaction which occurs at 750°C, 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.
