Abstract
The density, viscosity, and surface tension of Hastelloy (Ni-Cr-Mo alloy) in the molten state were measured under vacuum conditions. Due to the lack of data in the open literature, the values of these physical properties were compared with those of other compositions of similar nickel-based alloys (CMSX, RENE, Inconel). There was not much difference in viscosity and surface tension when compared with other alloys. The high viscosity of Hastelloy C-276 is considered to be the result of surface oxidation, and the viscosity increases as the surface tension decreases.
