The given figure shows the pressure-temperature phase diagram for H2O. Apply the Gibbs phase rule at points A,B, and C, and specify the number of degrees of freedom at each of the points, that is, the number of externally controllable variables that need to be specified to completely define the system.

Use the phase diagrams for Cu-Ni and Cu-Ag systems below to answer the question: Based on the mechanism, would you expect a solution containing 80 wt% Cu to be stronger if the remaining 20% of the alloy was Ni or Ag? Briefly explain

Using the Mg-Pb phase diagram below, if you start at point A and cool down very slowly to room temperature (point D), sketch the microstructure associated with each letter, determine what phases are present at each letter, determine the compositions for each phase, and determine the weight in each phase. The Mg-Pb mixture has 20 wt. % Pb in it. You start with 100 kg.

3. Platinum and gold are completely soluble in both the liquid and solid states. The melting point of platinum is 3225°F and that of gold is 1945°F. An alloy containing 40% gold starts to solidify at 2910°F by separating crystals of 15 percent gold in solid. An alloy containing 70% gold starts to solidify at 2550°F by separating crystals of 37% gold in solid. Draw the equilibrium diagram to scale on a piece of graph paper and label all points, lines and areas. For an alloy containing 70% gold (a) give the temperature of initial and final solidification. (b) Give the chemical composition and relative amounts of the phases present at 2440°F.
