Abstract

The surface tension of supercooled liquid Ni-15%Sn alloy was measured by the electromagnetic oscillating drop method over a wide temperature range from 1368K to 1915K. The maximum supercooling of 265 K (0.16 T_L) was achieved. Over the temperature range investigated, the measured surface tension shows a linear property expressed by σ_Ni-15%Sn=1316.7-1.01 (T-T_L)mN/m. On the basis of experimental data, the viscosity and the diffusion coefficient of Ni-15%Sn melt were derived, and we also analyzed the activation energy for Viscous flow and diffusion.
