Based on nucleation theory, the solid-liquid interfacial energy for ${\mathrm{Ni}}_{40}$${\mathrm{Pd}}_{40}$${\mathrm{P}}_{20}$ is estimated to be 100±2 mJ/${\mathrm{m}}^2$ from the nucleation frequency of ${\mathrm{Ni}}_{40}$${\mathrm{Pd}}_{40}$${\mathrm{P}}_{20}$ alloy glass. The value of the solid-liquid interfacial energy is found to be quite close to that estimated by means of an extension of Turnbull’s assumption for alloys.
