摘要

The surface tension of liquid Co-Mo alloys is calculated by the Monte Carlo (MC) method using embedded atom method (EAM) potentials. For liquid Co-10 percent Mo alloy, the calculated surface tension at the liquidus temperature is 1.51 N/m, which is 20 percent smaller than the experimental result. The temperature coefficient of the surface tension is 4.72 X 10~(-4)N/m centre dot K. The simulated surface tension of liquid Co-37.6 percent Mo alloy at the liquidus temperature is 1.95 N/m, which is only 2 percent lower than its measured value. The dependence of surface tension on the degree of undercooling of liquid Co-16 percent Mo and Co-30 percent Mo alloys has also been obtained. Comparison between the simulated and experimental results shows that better agreement is obtained with higher Mo content in the liquid alloys.
