Density and surface tension of molten cast irons

Computer-aided development of liquid-assisted metallurgical processes requires reliable basic data for the molten materials, including thermophysical properties such as density, surface tension, and viscosity. Cast irons belong to the group of Fe-C alloys of practical importance due to their good te...
