9.41 Consider a hypothetical eutectic phase diagram for metals A and B that is similar to that for the lead-tin system (Figure 9.8). Assume that: (1) a and B phases exist at the A and B extremes of the phase diagram, respectively; (2) the eutectic com- position is 36 wt% A-64 wt% B; and (3) the com- position of the a phase at the eutectic temperature is 88 wt% A-12 wt% B. Determine the composi- tion of an alloy that will yield primary B and total B mass fractions of 0.367 and 0.768, respectively.

For some given binary phase diagram, describe how you would: find the temperatures and compositions of all eutectic, eutectoid, peritectic, and congruent phase transformations write reactions for all these transformations for either heating or cooling (show an example).
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.
