| Fig.1 Schematics of continuous and transient heredities of fcc single crystal cluster cores, in which red and blue balls represent continuously and transiently inheritable atoms, respectively (t is the isothermal crystallization time; t0 is a designated moment for the reverse tracing of atom trajectories; Δt is the time interval; i = 1, 2, 3, … is recorded step number; tfcc and tSCC are the initial moments of transient heredity of fcc atoms and fcc single crystal cores, respectively; tinitial represents the initial moment of continuous heredity; tonset denotes the onset moment of nucleation corresponding to a critical nucleus; nc(t) and lc(t) are the quantity of continuously inheritable fcc atoms and the number of intercross-sharing (IS) linkages among continuously heritable fcc atoms in fcc single crystal clusters, respectively) |
