Abstract
The density and thermal expansion of the solid and liquid Inconel 718 alloy are measured by the dilatometer method and gamma-ray attenuation technique over the temperature range 293.15-1730 K. The density change during the solid-liquid phase transition is directly measured. A comparison of the obtained results with literature data is carried out.
