A supersaturated γ phase microstructure is produced in Ni-based superalloys using laser powder bed fusion (L-PBF) – the cooling rate arising from the process is shown to suppress the solid-state precipitation of the γ phase. The response of the m

A New Class of Alumina-Forming Superalloy for 3D Printing

Autor: Ghoussoub, JN, Klupś, P, Dick-Cleland, WJB, Rankin, KE, Utada, S, Bagot, PAJ, McCartney, DG, Tang, YT, Reed, RC

A new class of crack-resistant nickel-based superalloy containing high γ ′ fraction is studied for the laser-powder bed fusion (L-PBF) process. The effects of the (Nb+Ta)/Al ratio is emphasized, a strategy that is shown to confer excellent low-tem
