Izinga lokushisa recrystallization ofi-lanthanum-doped molybdenum wireiphakeme kunei-molybdenum wire ehlanzekile, futhi kungenxa yokuthi inani elincane le-La2O3 lingathuthukisa izakhiwo nesakhiwo socingo lwe-molybdenum. Ngaphandle kwalokho, umphumela wesigaba sesibili se-La2O3 unganyusa amandla okushisa egumbi lei-molybdenum wirefuthi uthuthukise izinga lokushisa legumbi ngemuva kokwenziwa kabusha kwekristalu.

I-Recrystallization Temperature Comparison: I-microstructure yocingo oluhlanzekile lwe-molybdenum ngokusobala yanwetshwa ku-900 ℃ futhi yaphinde yahlanganiswa ku-1000 ℃. Ngokukhuphuka kwezinga lokushisa le-annealing, okusanhlamvu kwe-recrystallization nakho kuyanda, futhi izicubu ezinama-fibrous ziyancipha kakhulu. Lapho izinga lokushisa le-annealing lifinyelela ku-1200 ℃, intambo ye-molybdenum yenziwe kabusha ngokuphelele, futhi i-microstructure yayo ikhombisa okusanhlamvu okufana okufanayo okulinganayo okuphinde kukhanye. Njengoba izinga lokushisa likhuphuka, okusanhlamvu kukhula ngokungalingani futhi kubonakala okusanhlamvu okumahhadla. Uma ifakwe ku-1500 ℃, intambo ye-molybdenum kulula ukuphuka, futhi isakhiwo sayo sibonisa okusanhlamvu okumahhadla kwe-quiaxed. Isakhiwo sefayibha ye-lanthanum-doped molybdenum wire siye sanwetshwa ngemva kokufakwa ku-1300 ℃, futhi umumo ofana nezinyo uvele emngceleni wefayibha. Ku-1400 ℃, okusanhlamvu okwenziwe kabusha kwavela. Ku-1500 ℃, ukuthungwa kwefayibha kwehle kakhulu, futhi ukwakheka okwenziwe kabusha kwavela ngokusobala, futhi okusanhlamvu kwakhula ngokungalingani. Izinga lokushisa lokuvuselela kabusha le-lanthanum-doped molybdenum wire liphakeme kunalelo locingo lwe-molybdenum oluhlanzekile, olubangelwa ikakhulukazi umthelela wezinhlayiya zesigaba sesibili se-La2O3. Isigaba sesibili se-La2O3 sivimbela ukufuduka komngcele wokusanhlamvu kanye nokukhula kokusanhlamvu, ngaleyo ndlela kukhuphule izinga lokushisa le-recrystallization.

Ukuqhathaniswa Kwezakhiwo Zemishini Yezinga Lokushisa Kwegumbi: Ukwelulwa kwentambo ye-molybdenum emsulwa kuyenyuka njengoba izinga lokushisa le-anneal likhuphuka. Lapho izinga lokushisa le-anneal liku-1200 ℃, ubude bufinyelela inani eliphezulu. Ubude buyancipha njengoba izinga lokushisa le-aneal likhuphuka. Ifakwe ku-1500 ℃, futhi ubude bayo bucishe bulingane noziro. Ukwelulwa kwentambo ye-molybdenum ye-La-doped kufana nentambo ye-molybdenum ehlanzekile, futhi izinga lokwelulwa lifinyelela umkhawulo omkhulu lapho lidonswa ku-1200 ℃. Bese-ke ubude buyehla ngokunyuka kwezinga lokushisa. Okuhlukile kuphela ukuthi izinga lokunciphisa lihamba kancane. Nakuba ukunwetshwa kwentambo ye-lanthanum-doped molybdenum yehliswa ngemva kokudonsa ku-1200 ℃, ubude buphakeme kunocingo oluhlanzekile lwe-molybdenum.
