Consider the phase diagram below. The three points A, B, and C are at concentrations of 27.3, 31.2, and 33.3 wt% Ni respectively. The ends of the tie line are at C1 = 25% wt% Ni and C2 = 35 wt% Ni. What are the weight fractions of the alpha phase at A and the L phase at B, as well as the alpha phase/L phase ratio at C?
