Density determination and simulation of Inconel 718 alloy at normal and metastable liquid states
Journal of Materials Science & Technology(2018)
Abstract
The density of liquid Inconel 718 alloy was experimentally measured by electrostatic levitation technique, where the maximum undercooling of 100K was realized for the commercial sample. The measured density of liquid Inconel 718 alloy is 7.39gcm−3 at the liquidus temperature of 1663K which was confirmed by DSC experiment, with the linear temperature coefficient of −6.89×10−4 gcm−3K−1. 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.
