Printability and Mechanical Properties of LPBF Ni-Based 625 and 244 Alloys
The advanced materials and manufacturing technologies (AMMT) program is investigating two Ni-based alloys of interest to the nuclear industry, alloy 625, due to its acceptable high temperature properties and availability in various forms, and Haynes 244, a promising low Cr high strength alloys for molten salt applications. These two alloys were fabricated by laser powder b…

Manufacturability and performance response of developed Ni-based alloys for reactor environments
Under the Advanced Materials and Manufacturing Technologies program, two Ni-based alloys fabricated by laser powder bed fusion (LPBF) at ORNL and laser powder directed energy deposition (LP-DED) at INL have been evaluated: γ′-strengthened Haynes 282 and solution-strengthened Inconel 625. Printing defects were observed in the LPBF 282 alloy fabricated using a Renishaw AM250…

LPBF MANUFACTURED ALLOYS 625 AND 282 AND PROPERTIES RELEVANT TO ADVANCED NUCLEAR COMPONENTS
Under the advanced materials and manufacturing technologies program, two Ni-based alloys fabricated by laser powder bed fusion (LPBF) have been evaluated, gamma’ strengthened Haynes 282 and solution strengthened 625. Large printing defects were observed in the LPBF 282 alloy fabricated using a Renishaw 250 machine, likely due to particle spattering during printing. Anneali…
