Kugwiritsa ntchito
1. Amagwiritsidwa ntchito makamaka ngati nodularizer popanga chitsulo chosungunuka.
2. Magnesium mu Ni-Nb ikhoza kuwonjezeredwa mu chitsulo chosungunuka bwino komanso mosamala kuti isunge zotulutsa ndi katundu wapadera wa chitsulo chopangidwa.
3. Nb imatha kusungunuka mu chitsulo cha nickel popanda kulekanitsidwa, ndipo magwiridwe antchito a Nb pang'onopang'ono mu chitsulo chosungunuka amadzipangitsa kukhala chowonjezera chogwira ntchito bwino, chotsika mtengo komanso chotetezeka pansi pake. Poyerekeza ndi zowonjezera zina zopanda Nb, imakhala ndi kuchira bwino ndipo imatha kuonetsetsa kuti kupanga kuli kokhazikika.
4. Nickel mu Ni-Nb alloys imagwira ntchito ngati graphitizator ndi perlite stabilizer, kotero mphamvu yokoka ndi mphamvu ya makina ya zinthuzo zitha kuchepetsedwa. Komanso pogwiritsa ntchito Ni-Nb, kusiyana kwa chidutswa chopepuka ndi cholemera kumachepa popanga. Komanso, imakhala ndi zotsatira zabwino kwambiri mu austenite ndi bainite ductile chitsulo.
