Density and volumetric expansion of the Inconel 718 alloy in solid and liquid states

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.
