(color online) (a) Al–Pb bond fraction and (b) MSF of Al₅₀Pb₅₀ alloy during different cooling processes. If the distance between two atoms is less than a given cutoff distance, which is equal to the position of the first minimum in the appropriate pair correlation function, then the pair of atoms is considered to form a bond. (c) Al–Pb bond fraction and (d) MSF as a function of cooling rate at different temperatures of cooling process.
