Gusaba
1.Bikoreshwa cyane nka nodularizer mugukora ibyuma byangiza.
2.Manyeziyumu muri Ni-Nb irashobora kongerwamo ibyuma bishongeshejwe neza kandi neza kugirango bigumane umusaruro numutungo wihariye wicyuma.
3.Nb irashobora gushonga mubyuma bya nikel cyane nta gutandukanya, kandi imikorere itinda ya Nb mubyuma byashongeshejwe ubwayo iba efficinet, ubukungu kandi bwizewe muri base inro. Ugereranije nibindi byongeweho bitarimo Nb, bifite gukira neza kandi birashobora kwemeza ko umusaruro uhagaze neza.
4.Nikel muri Ni-Nb alloys ikora nka graphitizator na stabilisateur ya perlite, bityo imbaraga za tensile hamwe nubukanishi bwibikoresho bishobora gutunganywa.Ikindi kandi hamwe no gushyira mu bikorwa Ni-Nb, itandukaniro ryumucyo nuduce twinshi twagabanutse mubikorwa.Ikindi kandi, gifite ingaruka nziza mubyuma bya austenite na bainite.
