Abstract
In the present study, Ni95Nb5 (wt. %) alloy samples are additively manufactured using selective laser melting (SLM) as a surrogate for Ni-based superalloys. Near porosity-free samples are fabricated utilizing a simple analytical model to predict melt pool dimensions, guide process parameter selection, and determine the defect-free printability map in the process parameter space. Ni95Nb5 mechanical testing specimens displayed consistent yield strengths (∼600 MPa) and ultimate tensile strengths (∼750 MPa) across a range of process parameters. These results show that with the proper selection of process parameters, SLM can produce parts with consistent mechanical properties in a wide process parameter space in simple alloying systems.
