1. Use the Cu-Ni phase diagram.
(a) Based on the phase diagram, comment on the solubility of Cu and Ni in each other and explain your answer.
(b)What type of solid solutions are the resulting alloys? Explain your answer.
(c)For a Cu-40Ni alloy(60wt%Cu, 40wt% Ni), determine the degrees of freedom and the phase composition at
(i)1300°C
(ii)1250°C
(iii)1200°C
