Fa'aaogāga
1.Mainly faʻaaogaina e avea o se nodularizer mo le gaosiga o le uʻamea lafo.
2.O le Magnesium i le Ni-Nb e mafai ona faʻaopoopoina i totonu o le uʻamea uʻamea sili atu le lelei ma le saogalemu ina ia mafai ai ona tausia le gaosiga ma le meatotino faʻapitoa o le uʻamea lafo.
3. O le Nb e mafai ona liusuavai i le nickel metal maualuga e aunoa ma se segreation, ma le faʻagesegese o gaioiga faʻaalia o le Nb i le uʻamea uʻamea e avea ai o ia ma se efficinet, tamaoaiga ma le saogalemu faʻaopoopo i le faavae inro.Faatusatusa i isi faʻaopoopoga e aunoa ma le Nb, e sili atu le toe faʻaleleia ma mafai ona faʻamautinoa o loʻo mautu le gaosiga.
4.O le Nickel i Ni-Nb alloys e galue e pei o le graphitizator ma le perlite stabilizer, o lea e mafai ai ona faʻamalosia le malosi faʻamalosi ma mea faʻainisinia o mea. Faʻatasi ai ma le faʻaogaina o le Ni-Nb, o le eseesega o le moli ma le mamafa o le faʻapipiʻiina o mea e faʻaitiitia i le gaosiga.
