• Grain Structure Control of Additively Manufactured Metallic Materials (2017, background): “For example, comparing with laser melting, electron beam melting (EBM) processes can introduce slower cooling rate due to potentially higher pre-heating temperatures on building substrate and larger hatch spacing, less residual stress may be stored in the as-built materials to induce recrystallizati”
• Computational modeling of residual stress formation during the electron beam melting process for Inconel 718 (2015, unknown): “Laser free formed material showed residual stress of 50-80 % of the yield stress [20], whereas EBM material shows only 5-10 % of UTS [21].”
• Additive manufacturing of metallic components by selective electron beam melting — a review (2016, background): “This is an essential difference to SLM samples which are generally built at much lower temperatures.(15) As a result, there is a high level of residual stresses in SLM materials.”
