Inconel 718 ist der meiste widely used nickel superalloy in additive manufacturing (laser powder bed fusion). Sein relatively wide processing window compared zu andere superalloys makes es mehr forgiving von LPBF parameter variations. However, post-process heat treatment ist kritisch: solution treatment bei 980°C für 1 hour followed durch two-schritt aging (720°C/8h furnace cool + 620°C/8h luft cool) ist erforderlich zu develop der gamma-double-prime strengthening phase das gives IN718 sein hoch-temperature properties.
