Grain structure evolution in Inconel 718 during selective electron beam melting

Materials Science and Engineering: A, 2016
Abstract Selective electron beam melting (SEBM) is an additive manufacturing method where complex parts are built from metal powders in layers of typically 50 µm. An electron beam is used for heating (about 900 °C building temperature) and selective melting of the material.

Dual-detector electronic monitoring of electron beam selective melting

Journal of Materials Processing Technology, 2021
Abstract Electron Beam Selective Melting (EBSM) is an advanced additive manufacturing technique used in many vital industrial fields. However, the lack of process monitoring and quality control is largely restricting the industrial application. The optical-based monitoring methods are hindered by the complex working conditions, such as intensive ...

Melt pool dynamics during selective electron beam melting

Applied Physics A, 2013
Electron beam melting is a promising additive manufacturing technique for metal parts. Nevertheless, the process is still poorly understood making further investigations indispensable to allow a prediction of the part’s quality. To improve the understanding of the process especially the beam powder interaction, process observation at the relevant time ...
