Abstract

Abstract: Density of molten Ni and Ni-W alloys was measured in the temperature range of 1773~1873 K with a sessile drop method. The density of molten Ni and Ni-W alloys trends to decrease with increasing temperature. The density and molar volume of the alloys trend to increase with increasing W concentration in the alloys. The calculation result shows an ideal mixing of Ni-W alloys.

Key words: Density, Molar volume, Ni-W alloys, Structure
