Journal ArticleDOI
Characterization of the strength of support structures used in powder bed fusion additive manufacturing of Ti-6Al-4V
Lourdes D. Bobbio,Shipin Qin,Alexander J. Dunbar,Panagiotis (Pan) Michaleris,Allison M. Beese +4 more
TL;DR: In this paper, the tensile structural strength of support structures with four different 2-dimensional lattice geometries was evaluated by fabricating samples composed of solid material on the bottom, followed by support material in the middle, and finally, a solid material layer on the top.
Journal ArticleDOI
Anisotropic multiaxial plasticity model for laser powder bed fusion additively manufactured Ti-6Al-4V
TL;DR: In this article, the multiaxial yield and plastic flow behavior of Ti-6Al-4V manufactured in two orientations via laser powder bed fusion (L-PBF) additive manufacturing was investigated.
Journal ArticleDOI
Multiaxial plasticity and fracture behavior of stainless steel 316L by laser powder bed fusion: Experiments and computational modeling
TL;DR: In this paper, the multiaxial large deformation and ductile fracture behavior of laser powder bed fusion (L-PBF) additively manufactured austenitic 316L stainless steel was experimentally measured.
Journal ArticleDOI
Plasticity and fracture behavior of Inconel 625 manufactured by laser powder bed fusion: Comparison between as-built and stress relieved conditions
TL;DR: In this paper, the influence of stress relief on the plasticity and fracture behavior of Inconel 625 fabricated through laser powder bed fusion additive manufacturing (AM) was investigated, showing similar grain structures but the presence of a ~10vol % δ phase in the stress relieved condition, and no δ in the as-built condition.
Journal ArticleDOI
Unveiling dislocation characteristics in N i 3 Al from stacking fault energy and ideal strength: A first-principles study via pure alias shear deformation
TL;DR: In this paper, a pure alias shear deformation has been applied to shed light on dislocation characteristics in Ni-based superalloys using the predicted stacking fault energy (i.e., the \ensuremath{\gamma} surface) and ideal shear strength.
