A lead-tin alloy, at equilibrium, consists of both $?$ and $?$ phases. If the composition of the $?$ phase is $18\mathrm{wt}\%\mathrm{Sn}$ and mass fraction of the primary $?$ microconstituent is 0.55 , determine the following: (a) the temperature of the alloy (b) the composition of the $?$ phase (c) the composition of the alloy You may find Animated Graph: Figure 10.8 useful. (a) ${}^{?}\mathrm{C}$ (b) $wt\%$ Sn (c) wt $\%$ Sn
