Ubushyuhe bwa rerystallisation ya lanthanum-dope ya molybdenum irarenze insinga ya molybdenum, kandi ni ukubera ko umubare muto wa La2O3 ushobora kunoza imiterere n'imiterere y'insinga ya molybdenum. Byongeye kandi, La2O3 icyiciro cya kabiri gishobora nanone kongera ubushyuhe bwicyumba cyumubyimba wa molybdenum kandi bikazamura ubushyuhe bwicyumba nyuma yo kongera gukora.
Kugereranya Ubushyuhe bwo Kugarura Ubushyuhe: Microstructure ya wire ya molybdenum biragaragara ko yaguwe kuri 900 ℃ hanyuma igashyirwa kuri 1000 ℃. Hamwe n'ubushyuhe bwa annealing bwiyongera, ibinyampeke byongeye kwiyongera, kandi fibrous tissue igabanuka cyane. Iyo ubushyuhe bwa annealing bugeze kuri 1200 ℃, insinga ya molybdenum yarasubiwemo rwose, kandi microstructure yayo yerekana ibinyampeke bisa nkibingana. Mugihe ubushyuhe bwiyongera, ingano zikura zingana kandi zigaragara nkintete. Iyo ihujwe kuri 1500 ℃, insinga ya molybdenum iroroshye kumeneka, kandi imiterere yayo yerekana ingano zingana zingana. Imiterere ya fibre ya lanthanum-dope molybdenum yagutse nyuma yo gufatirwa kuri 1300 and, kandi ishusho imeze amenyo yagaragaye kumupaka wa fibre. Kuri 1400 ℃, ibinyampeke byongeye kugaragara. Kuri 1500 ℃, fibre fibre yagabanutse cyane, kandi imiterere yongeye kugaragara yagaragaye, kandi ingano zarakuze zingana. Ubushyuhe bwa rerystallisation ya lanthanum-dope molybdenum irarenze iy'umugozi wa molybdenum usukuye, biterwa ahanini n'ingaruka za La2O3 ibice bya kabiri. Icyiciro cya kabiri cya La2O3 kibuza imbibi kwimuka kwimuka no gukura kwimbuto, bityo ubushyuhe bwongera kwiyongera.
Icyumba Ubushyuhe bwa Byumba Ibikoresho Kugereranya: Kurambura insinga nziza ya molybdenum byiyongera hamwe nubushyuhe bwa annealing bwiyongera. Iyo ubushyuhe bwa anneal kuri 1200 ℃, kuramba bigera ku giciro kinini. Kurambura bigabanuka hamwe n'ubushyuhe bwa anneal bwiyongera. Bishyizwe kuri 1500 ℃, kandi kurambura kwayo bingana na zeru. Kurambura umugozi wa La-dope molybdenum bisa ninsinga ya molybdenum yera, kandi igipimo cyo kuramba kigera kuri byinshi iyo gishyizwe kuri 1200 ℃. Hanyuma kurambura kugabanuka hamwe n'ubushyuhe bwiyongera. Gusa ikinyuranyo nigipimo cyo kugabanuka kiratinda. Nubwo kurambura umugozi wa lanthanum-dope molybdenum bigenda gahoro nyuma yo gufatirwa kuri 1200 ℃, kurambura gusumba insinga ya molybdenum.
