Abstract
The density of liquid Inconel 718 alloy was experimentally measured by electrostatic levitation technique, where the maximum undercooling of 100 K was realized for the commercial sample. The measured density of liquid Inconel 718 alloy is 7.39 g cmâ3 at the liquidus temperature of 1663 K which was confirmed by DSC experiment, with the linear temperature coefficient of â6.89 Ã 10â4 g cmâ3 Kâ1. Correspondingly, four ternary Ni-Cr-Fe compositions were designed to simulate the density of liquid Inconel 718 alloy with 16000 atoms, from which the liquid structure is revealed by pair distribution function. The predicted result shows a remarkable enhancement with the decrease of temperature at the first neighbor distance.
