Abstract Scope A novel medium entropy alloy (MEA) with oxide dispersion strengthening (ODS), called GRX-810, has been recently designed for laser based additive manufacturing (AM). Such alloy exhibits significantly improved mechanical and oxidation-resistant properties at high temperatures, compared to standard nickel-based alloys. However, this MEA-ODS alloy has been so far exclusively employed for component fabrication via laser powder bed fusion (L-PBF). To enable broader incorporation of novel materials into larger-scale components, this work investigated the use of HVOF thermal spray as an additive manufacturing technique to be explored as a processing path for deposition of GRX-810 alloy. In this talk, it will be exposed our efforts in the development of HVOF processing maps by exploring the effects of key deposition parameters, along with microstructure characterization and mechanical properties evaluation of the as-deposited material.
