Table I. The various metals, their solid phase, and their densities in the liquid and solid states used to estimate the characteristic undercooling T*. The density values are evaluated at the melting point TMP and were obtained from Ref. 24 unless otherwise indicated. The crystal phase determined the values of gS used from Ref. 23. The T values were obtained from Ref. 22, while T was evaluated from the model presented here.

Table II. Table showing surface tension, characteristic undercooling temperature TUC, and temperature of minimum barrier energy TN. The surface tension values were obtained from Ref. 29 and were used to estimate the barrier energy and critical radius. The T values were calculated from Ref. 22, while the T is the theoretical value for the characteristic undercooling estimated from our theory. TN is the temperature at which the nucleation barrier is a minimum.
