2- Cu and Ag are completely soluble in each other in liquid state. They form an eutectic mixture at 70% Ag. The eutectic reaction occurs at 780 C. The melting points of Cu and Ag are 1080 C and 960 C respectively. The max solubility of Ag in Cu is 8 % and that of Cu in Ag is 9 %. The solid solubility is decreased with temperature to be zero at room temperature. - Construct the equilibrium phase diagram. - Make phase analysis of 70 % Cu - 30 % Ag alloy at 1000 C, and at 600 C.
