Q2 (a) Equilibrium phase diagram for Copper (Cu) Nickel (Ni) system is CLO3 shown below. Consider a 50wt%Ni50wt%Cu alloy slowly cooled (8) from 1400C to 1200C, and answer the following questions: (i) At what temperature does the first solid phase form? (ii) What is the composition of this solid phase? (iii)At what temperature does the last remaining liquid solidify to complete solidification? (iv) What is the composition of this last remaining liquid phase?
