10.11* The phase diagram of an alloy that has a eutectoid transformation is shown in Figure 10.33 . a. Sketch the Gibbs free energy curves for this alloy at $T=T^{\prime }$. b. Show that the $\alpha /\gamma$ solvus must enter the $\alpha /\beta$ two-phase field (as shown by the arrow). c. Besides $T=T^{\prime }$, sketch the Gibbs free energy curves for $T_1,T_2,T_3$, and show how taut string method can be used to construct the phase diagram. Figure 10.33 A eutectoid phase diagram showing the extension of the $\alpha /\gamma$ equilibrium curve into the $\alpha /\beta$ solvus.
