Measurement and Analyses of Molten Ni-Co-Al Alloy Density

Keywords： Density

The density of molten Ni-Co-Al alloy was measured using a modified pycnometric method. It has been found thatthe density of the molten Ni-Co-Al alloy decreases with increasing temperature, Co concentration and the ratioof Co concentration to Ni concentration in the alloy. The coefficient of volume expansion of the molten Ni-Co-Al alloy decreases with increasing Co concentration and the ratio of Co concentration to Ni concentration. Thetemperature coefficient of density increases with increasing the Co concentration or the ratio of Co concentration toNi concentration in the alloy. The density of the molten Ni-Co-Al alloy as functions of both temperature and Coconcentration was expressed.
