Abstract

The density of molten Ni-W alloys was measured with a modified pycnometric method. It is found that the density of the molten Ni-W alloys decreases with temperature rising, but increases with the increase of tungsten concentration in the alloys. The molar volume of molten Ni-W binary alloys increases with the increase of temperature and tungsten concentration. The partial molar volume of tungsten in liquid Ni-W binary alloy has been calculated approximately as (−1.59+5.64×10−3T)×10−6m3·mol−1.
