Cooling curves are obtained for a series of Cu- Ag alloys. Use the data in Figure 4 to produce the Cu-Ag phase diagram. The maximum solubility of Ag in Cu is 7.9% and the maximum solubility of Cu in Ag is 8.8%. The solubilities at room temperature are near zero.
A hypothetical eutectic phase diagram for metals A and B shows that cooling a liquid melt with a concentration of 50 wt% A-50 wt% B to just below 625 °C (eutectic isotherm temperature) results in simultaneous formation of alpha and beta phases. The phase diagram also shows that alpha (A rich) and beta (B rich) phases exist at left and right extremes of the phase diagram, respectively. At the eutectic isotherm temperature, the maximum solubility of B in A and A in B is 10 wt% and 5 wt%, respectively. The phase diagram does not have any intermetallic compounds. A new solid alloy is made by melting together 86 gr of a 40 wt% A-60 wt% B alloy with 136 gr of 65 wt% A-35 wt% B alloy followed by cooling the melt to 400 °C. If the new alloy is heated up from 400 °C to just below 625 °C, answer the following questions: a. Calculate the overall alloy composition. b. Determine phases present and calculate their respective masses. Calculate the masses of the primary phase, eutectic phase, and…
