Figure 2. Microstructural evolutions for Ostwald ripening. The screenshots of representative microstructure images of five coupled fields, including one compositional field (c) and four structural order parameters (η_i, i = 1-4) with distinct microstructure features. The input parameters include mobility (M), average initial composition (c_a), and final composition (c_f) for four panels are: (A) M = 4.811, c_a = 0.545, c_f = 0.276; (B) M = 4.864, c_a = 0.500, c_f = 0.279; (C) M = 4.993, c_a = 0.481, c_f = 0.344; (D) M = 4.717, c_a = 0.499, c_f = 0.187.
