Isicelo
1. Isetshenziswa kakhulu njenge-nodularizer yokwenza insimbi ethambile.
2. I-Magnesium ku-Ni-Nb ingafakwa ensimbini encibilikisiwe kahle nangokuphephile ukuze kugcinwe umkhiqizo kanye nempahla ekhethekile yensimbi ephonswe.
3. I-Nb ingancibilikiswa kakhulu ngensimbi ye-nickel ngaphandle kokuhlukaniswa, futhi ukusebenza kancane kokusabela kwe-Nb ensimbini encibilikisiwe kuyenza ibe yisithasiselo esisebenza kahle, esingabizi futhi esiphephile esisekelweni sayo. Uma iqhathaniswa nezinye izithasiselo ngaphandle kwe-Nb, inokubuyiselwa okungcono futhi ingaqinisekisa ukuthi ukukhiqizwa kuzinzile.
4. I-Nickel kuma-alloy e-Ni-Nb isebenza njenge-graphitizator kanye ne-perlite stabilizer, ngakho-ke amandla okudonsa kanye nempahla yomshini wezinto zingathuthukiswa. Futhi ngokusetshenziswa kwe-Ni-Nb, umehluko wengxenye yokukhipha elula nesindayo uyancishiswa ekukhiqizweni. Ngaphezu kwalokho, inomphumela omuhle kakhulu ku-austenite kanye ne-bainite ductile cast iron.
