Processing And Corrosion Behavior Of Metal Powder Blends In LPBF
World PM2022 Proceedings, 2022 Laser Powder Bed Fusion (LPBF) has become an attractive alternative to conventional processing routes over the past years. While some alloys are already processed in series production, the overall amount of available materials is low. Due to the high price of specially atomized powders, material variation is often neglected.

On the interplay of microstructure and residual stress in LPBF IN718 [PDF]
Journal of Materials Science, 2020 AbstractThe relationship between residual stresses and microstructure associated with a laser powder bed fusion (LPBF) IN718 alloy has been investigated on specimens produced with three different scanning strategies (unidirectional Y-scan, 90° XY-scan, and 67° Rot-scan).

Lamellar Spacing Modelling for LPBF Aluminum Parts
Journal of Manufacturing and Materials Processing, 2022 The high cooling rates reached during metal additive manufacturing (MAM) generate microstructures very different from those obtained by other conventional manufacturing methods. Therefore, research about the modeling of this type of microstructure is of great interest to the MAM community.

Scan path resolved thermal modelling of LPBF
Additive Manufacturing Letters, 2022 Laser powder bed fusion product quality depends on process parameters (e.g. laser power, scan speed, etc.) and on the scan strategy. The accuracy by which a feature outline is printed defines the surface finish, workpiece fatigue behavior and the extent of post processing needed to achieve surface quality specifications. In this paper we develop a semi-
