A 74 wt% Ni-26 wt% Cu alloy is heated to a temperature within the ? + liquid phase region. If the composition of the phase is 80 wt% Ni, using figure 10.3 determine
(a) The temperature of the alloy oC
(b) The composition of the liquid phase wt. % Ni
(c) The fraction of the phase
(d) The fraction of the liquid phase
