Abstract Scope |
This study investigated the room temperature mechanical behavior of Monel K500 fabricated using laser powder bed fusion (L-PBF) and laser powder directed energy deposition (LP-DED) technologies. The fabricated specimens underwent heat treatment involving hot isostatic pressing, solution annealing, and aging. The mechanical properties of the test specimens were evaluated using uniaxial tensile and fully reversed strain-controlled fatigue testing at room temperature. L-PBF specimens showed higher strength and lower ductility compared to the LP-DED counterparts. The LP-DED specimens showed longer fatigue life than the L-PBF specimens. The fracture surfaces were analyzed to investigate different crack initiation and failure mechanisms. |
