In the region indicated with an arrow in the phase diagram shown below, which of the following statements are true? 1300 L (liquid) - . T(°C) 1200 20 36 40 wt% Ni liquidus solidus α (solid) 50 Select one or more: a. The proportion of a phase increases going from right to left at a fixed temperature. b. The relative weight fractions of L and a phases can be determined quantitatively c. The proportion of "L" phase increases going from right to left at a fixed temperature Od. There are solid grains mixed with a liquid phase Consider the phase diagram below. The three points A, B, and C are at concentrations of 26.8, 31.3, and 33 wt% Ni respectively. The ends of the the 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?
