Thermal stability and influence of Y2O3 dispersoids on the heat treatment response of an additively manufactured ODS Ni–Cr–Al–Ti γ/γ′ superalloy

The post-processing treatment response of a Y2O3 oxide-dispersion-strengthened (ODS) and γ/γ′-strengthened Ni–8Cr–5.5Al–1Ti (wt.%) model alloy, produced by laser powder bed fusion (L-PBF) is studied. The solutionizing treatment at 1260 °C induces significant recrystallization of the initial elongate...
