Igwe ọkụ recrystallization nke lanthanum-doped molybdenum waya dị elu karịa waya molybdenum dị ọcha, ọ bụkwa n'ihi na obere La2O3 nwere ike imeziwanye njirimara na nhazi nke waya molybdenum.E wezụga nke abụọ, mmetụta La2O3 nke abụọ nwekwara ike ịbawanye ike ụlọ okpomọkụ nke waya molybdenum ma melite nrịkasị nke ụlọ ahụ mgbe recrystallization gasịrị.
Ntụle ọnọdụ okpomọkụ recrystallization: O doro anya na a gbasaa microstructure nke waya molybdenum dị ọcha na 900 ℃ ma megharịa ya na 1000 ℃.Site na mmụba okpomọkụ na-ebelata ahụ, mkpụrụ ọka recrystallization na-abawanye, anụ ahụ fibrous na-ebelata nke ukwuu.Mgbe okpomọkụ na-ekpo ọkụ ruru 1200 ℃, waya molybdenum emezigharịla kpamkpam, na microstructure ya na-egosi mkpụrụ osisi recrystallized na-enweghị atụ.Ka okpomọkụ na-abawanye, ọka na-eto eto n'ụzọ na-ezighi ezi ma na-egosi oke ọka.Mgbe annealed na 1500 ℃, molybdenum waya dị mfe ịgbaji, na usoro ya na-egosi keadighi rarii ọka equiaxed.Nhazi eriri nke lanthanum-doped molybdenum waya gbasapụrụ mgbe agbachara ya na 1300 ℃, na udi yiri eze pụtara n'ókè nke eriri ahụ.Na 1400 ℃, ọka ndị recrystallized pụtara.N'ihe dị ka 1500 ℃, eriri eriri ahụ belatara nke ọma, na nhazigharị nke recrystallized pụtara n'ụzọ doro anya, ọka ndị ahụ toro n'ụzọ na-ezighi ezi.The recrystallization okpomọkụ nke lanthanum-doped molybdenum waya dị elu karịa nke dị ọcha molybdenum waya, nke bụ tumadi n'ihi mmetụta nke La2O3 nke abụọ akụkụ ahụ.Usoro nke abụọ nke La2O3 na-egbochi ịkwaga oke oke ọka na uto ọka, si otú a na-abawanye okpomọkụ recrystallization.
Ntụle Nrụmọrụ Igwe Ọkụ nke ime ụlọ: elongation nke waya molybdenum dị ọcha na-abawanye na okpomọkụ na-ekpo ọkụ na-abawanye.Mgbe anneal okpomọkụ na 1200 ℃, elongation ruru kacha uru.Ntugharị ahụ na-ebelata ka okpomọkụ anneal na-abawanye.Annealed na 1500 ℃, na elongation ya fọrọ nke nta ka hà efu.Mgbatị nke La-doped molybdenum waya yiri waya molybdenum dị ọcha, na elongation ọnụego erute kacha mgbe annealed na 1200 ℃.Mgbe ahụ elongation na-ebelata na okpomọkụ na-abawanye.Naanị ihe dị iche bụ ọnụ ọgụgụ mbelata dị nwayọọ.Ọ bụ ezie na elongation nke lanthanum-doped molybdenum waya na-eji nwayọọ nwayọọ mgbe annealing na 1200 ℃, elongation dị elu karịa ọcha molybdenum waya.
