Process map of Laser Beam Powder Bed Fusion for Nickel-Based Superalloy Created by Numerical Analysis Considering Melting and Solidification

Year: 2020

Type: article

Abstract: A process map for searching for optimum conditions for Ni-based superalloys in laser beam powder bed fusion type additive manufacturing was prepared by numerical calculation of transient heat transfer analysis considering the melting and solidification around the laser track. For Inconel 718 alloy, the melting and solidification phenomenon around the laser track was numerically calculated using the physical properties of the powder, solid, and liquid in the range of laser scanning speed 750-1500mm/s and laser output 150-300W, and the weld pool size was calculated.
