What is the eutectic temperature? c. What is the eutectic concentration (in mass percent)? d. What is the composition of the Ag in the solid solution at the eutectic temperature? e. What is the composition of the Cu in the solid solution at the eutectic temperature? f. At 600°C what is the composition of the solid solution in wt % Cu? g. At 600°C what are the relative amounts (in wt % Cu) of the two components in the solution? and h.At the eutectic composition, sketch (on the diagram) what the microstructure of the material would look like at 1000 °C and 650 C i.
