Automated SEM/EDS Analysis for Assessment of Contamination and Non-Metallic Inclusions of Powders and Additive Manufactured Inconel 718 Alloy

摘要

Inconel 718 alloy can consistently be additive manufactured. However, cross-contamination of the powder precursors can occur during powder production, handling and additive manufacturing. The use of automated SEM/EDX is reported to assess contamination and non-metallic inclusions along with the corresponding microstructures in the powders and additive manufactured IN718 alloy product which was heat-treated as per AMS5662.
