Abstract
Haynes 214, a nickel-based superalloy, and its oxide dispersion-strengthened (ODS) versions (addition of 0.3, and 1.5 wt. % yttria (Y2O3)) have been successfully fabricated using selective laser melting (SLM). For each feedstock formulation, optimal processing conditions were identified and high temperature tensile testing coupons were produced. Feedstock preparation and laser scanning strategy have been proven to be critical in the dispersion of nanoparticles in the metal matrix, as well as preventing the formation of extensive crack networks. The impact of Y2O3 addition on the high-temperature tensile properties of Haynes 214 was evaluated and discussed.
