[HTML][HTML] Selective compositional range exclusion via directed energy deposition to produce a defect-free Inconel 718/SS 316L functionally graded material
In this research, additively manufacturing a functionally graded material (FGM) with a
compositional range of Ni-based Inconel superalloy (Inconel 718) and Fe-based stainless
steel (SS 316L) via directed energy deposition (DED) was examined. The microstructural
transformation, defect behavior, and Vickers hardness of the material were each determined
as a function of the discrete chemical composition of the FGM varied in steps of 10 wt% of
the two materials across its length. In particular, for the specific compositions of 30 wt …
