Computational Investigation on the Combined Effect of Applied Strain and Pore Configuration on Strain Concentrators in Additively Manufactured Metals

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Metal additive manufacturing (AM) provides a pathway for creating highly optimized components that would be difficult to produce using traditional manufacturing methods. However, regardless of printing parameters or postprocessing, porosity remains a prevalent challenge in AM components because strain concentrates in the vicinity of the pore ...

MAR-M247 Ni-based superalloy metal 3D printing with Electron Beam Powder Bed Fusion

open access: yes
Abstract This study explores the influence of scanning strategies on microstructure evolution using electron beam powder bed fusion (EB-PBF) of MAR-M247, a Ni-based superalloy. An energy density that produces minimum cracking was established by raster melting, and subsequently applied to spot melting to investigate how spot melting strategy ...
