The recrystallization kutentha kwawaya wa lanthanum-doped molybdenumndi apamwamba kuposawaya woyera molybdenum, ndipo ndi chifukwa chochepa cha La2O3 chikhoza kusintha mawonekedwe ndi mawonekedwe a waya wa molybdenum. Kupatula apo, gawo lachiwiri la La2O3 litha kuwonjezera mphamvu ya kutentha kwa chipindawaya wa molybdenumndi kusintha kutentha kwa chipinda brittleness pambuyo recrystallization.

Recrystallization Kutentha Kuyerekeza: The microstructure wa waya woyera molybdenum mwachionekere anakulitsa pa 900 ℃ ndi recrystallized pa 1000 ℃. Ndi kutentha kwa annealing, mbewu za recrystallization zimawonjezeka, ndipo minofu ya fibrous imachepetsa kwambiri. Kutentha kwa annealing kukafika pa 1200 ℃, waya wa molybdenum wakonzedwanso, ndipo mawonekedwe ake amawonetsa njere zofananira zofananiranso. Kutentha kumawonjezeka, njereyo imakula mosafanana ndipo imaoneka ngati njere zolimba. Ikalumikizidwa pa 1500 ℃, waya wa molybdenum ndi wosavuta kuthyoka, ndipo mawonekedwe ake amawonetsa njere zolimba. Mapangidwe a ulusi wa waya wa lanthanum-doped molybdenum adawonjezedwa pambuyo pa 1300 ℃, ndipo mawonekedwe ngati dzino adawonekera kumalire a ulusi. Pa 1400 ℃, njere zobwezeretsedwa zidawonekera. Pa 1500 ℃, mawonekedwe a ulusiwo adatsika kwambiri, ndipo mawonekedwe opangidwanso adawonekera, ndipo njerezo zidakula mosagwirizana. The recrystallization kutentha kwa lanthanum-doped molybdenum waya ndi apamwamba kuposa wa koyera molybdenum waya, amene makamaka chifukwa cha zotsatira za La2O3 gawo lachiwiri particles. Gawo lachiwiri la La2O3 limalepheretsa kusamuka kwa malire a tirigu ndi kukula kwambewu, motero kumawonjezera kutentha kwa recrystallization.

Kuyerekeza Kwakatundu Wazipinda: Kutalikira kwa waya wa molybdenum kumawonjezeka ndi kutentha kwa anneal kumawonjezeka. Pamene kutentha kwa anneal pa 1200 ℃, elongation imafika pamtengo wapatali. Elongation imachepa ndi kutentha kwa anneal kumawonjezeka. Yopangidwa ndi 1500 ℃, ndipo kutalika kwake kumakhala kofanana ndi ziro. The elongation wa La-doped molybdenum waya ndi ofanana ndi koyera molybdenum waya, ndi mlingo elongation kufika pazipita pamene annealed pa 1200 ℃. Ndiyeno elongation amachepetsa ndi kutentha kuwonjezeka. Chosiyana chokha ndicho kuchepetsa kuchepetsa ndi pang'onopang'ono. Ngakhale elongation wa lanthanum-doped molybdenum waya imachedwa pambuyo annealing pa 1200 ℃, elongation ndi apamwamba kuposa koyera molybdenum waya.
