Fig.9 Comparisons of cellular automation (CA) simulated and experimental results of solidification grain structure in titanium alloy ingot[29] (a), Ni-based superalloy ingot[53] (b), and bearing steel ingot[32] (h—depth of molten pool, R—radius of melting pool. The A1 and A2 regions are the columnar crystal regions corresponding to the simulation results and the experimental results, respectively. The B1 and B2 regions are the central equiaxed crystal regions corresponding to the simulation results and the experimental results, respectively, and the remaining regions are the surface fine grain regions corresponding to the two results) (c)
