Machine Learning-Enabled Competitive Grain Growth Behavior Study in Directed Energy Deposition Fabricated Ti6Al4V
TL;DR: In this paper, an artificial neural network (ANN) was used to investigate the relation between the grain boundary tilt angle and three causative factors, namely the thermal gradient, crystal orientation and Marangoni effect.

Effect of Post Treatment on the Microstructure, Surface Roughness and Residual Stress Regarding the Fatigue Strength of Selectively Laser Melted AlSi10Mg Structures
Wolfgang Schneller,Martin Leitner,Sebastian Pomberger,Sebastian Springer,Florian Beter,Florian Grün +5 more
TL;DR: In this paper, the effect of the unprocessed (as-built) surface and residual stresses, regarding the fatigue behavior for each condition, was assessed by tension-compression high-cycle fatigue tests under a load stress ratio of R = −1.

Microstructural Development in As Built and Heat Treated IN625 Component Additively Manufactured by Laser Powder Bed Fusion
Holden Hyer,Ryan Newell,Dan Matejczyk,Sinsar Hsie,Mason Anthony,Le Zhou,Cathy Kammerer,Yongho Sohn +7 more
TL;DR: In this article, the microstructure was examined with optical, scanning electron, and transmission electron microscopy, and changes in phase constituents and micro-structure were documented as a function of heat treatment and component geometry.

TiAl/RGO (reduced graphene oxide) bulk composites with refined microstructure and enhanced nanohardness fabricated by selective laser melting (SLM)
TL;DR: In this paper, the authors investigated the effect of laser scan line spacing on the microstructure, phase evolution and nanohardness of Ti-48Al-2Cr-2Nb/RGO composite.
Journal ArticleDOI
Spatial and temporal variation of hardness of a printed steel part
TL;DR: In this paper, the evolution of hardness of a tool steel part at various locations can be calculated using computed thermal cycles and a Johnson-Mehl-Avrami kinetic relation, which can serve as a basis for tailoring the hardness of some additively manufactured parts.
