Nimonic 90 Alliage ya nickel .
Nimonic 90 (UNS N07090) ezali superalloy ya nickel-Basé na performance ya malamu mingi na série nimonique. Na kotalela 80a nimonique, ematisaka lisusu biloko oyo ezali na kati ya titane mpe aluminium mpe ekɔtisaka cobalt. Na kotombolaka effet ya renforcement ya ba précipitations ya phase ' (ni₃(al,ti)), ezali na haut niveau ya likolo-Surccene ya température, résistance ya creep mpe stabilité microstructurelle. Esalelamaka mingimingi na key high-ba composants ya température oyo ememaka ba charges ya likolo na températures na se ya 900 degrés .
