In this Ni-Cu alloy phase diagram, if we lower the temperature down from \( T_{b}\left(1250^{\circ} \mathrm{C}\right) \) to a slightly lower than \( T_{b} \) (1249.5 \( \left.{ }^{\circ} \mathrm{C}\right) \), we expect the compoisition of liquid to bi higher than \( \mathrm{C}_{L} \) lower than \( \mathrm{C}_{L} \) same as \( \mathrm{C}_{L} \) none of the above In this Ni-Cu alloy phase diagram, if we lower the temperature down from \( \mathrm{T}_{\mathrm{b}}\left(1250^{\circ} \mathrm{C}\right) \) to a slightly lower than \( \mathrm{T}_{\mathrm{b}}\left(1249.5^{\circ} \mathrm{C}\right) \), we expect the compoisition of solid to be: Higher than Cox lower than Cox same as Co none of the above
