Iyo yekudzokorora tembiricha ye lanthanum-yakaitwa molybdenum waya yakakwira kupfuura yakachena molybdenum waya, uye ndeyekuti chidiki chidiki cheLa2o3 chinogona kuvandudza zvivakwa uye chimiro cheMolybdenum waya. Kunze kwezvo, LA2O3 Chikamu chechipiri Chiverengero chinogona zvakare kuwedzera tembiricha yekudziya yeMolbdenum waya uye kuvandudza tembiricha tembiricha mushure mekudzokorora.
Recrystallization tembiricha yekudziya: Iyo microsture yeiyo yakachena molybdenum waya yaive pachena yakawedzera pa900】 uye retrystallized pa1000】. Nekudziya kwekudzidzira kuwedzera, rondedzero yekudzokorora zvakare kuwedzera, uye matipi emuti zvakanyanya kuderedza. Kana tembiricha inosvika 1200 ℃, Molybdenum waya yakadzokororwa zvizere, uye microcenture yayo inoratidza yunifomu yakaenzana yakaenzana yakaenzana. Sezvo tembiricha yekuwedzera, zviyo zvinokura zvisina kukodzera uye zvinoonekwa zviyo. Paakashongedzwa na1500 ℃, iyo Molybdenum Wire iri nyore kuputsa, uye chimiro chayo chinoratidza zvinyorwa zveCoarsed equiaxed. Iyo fiber chimiro che lanthanum-dived molybdenum waya yakawedzera mushure mekushambidzwa pa1300 ℃, uye chimiro chakaonekwa chakaonekwa pamu muganho weiyo fibheri. Pa1400 ℃, iyo dzokorora zviyo zvakaonekwa. Pana 1500 ℃, iyo fiber tarisiro yakadzikira zvikuru, uye chimiro chedzidzo chakaonekwa sezviri pachena, uye zviyo zvakakura zvakavapo. Iyo yekudzokorora tembiricha ye lanthanum-yakagadziriswa molybdenum waya yakakwira kupfuura iyo yeiyo yakachena molybdenum waya, iyo inonyanya kukonzerwa nemhedzisiro yeLa2o3 yechipiri chikamu chikamu. Iyo LA2O3 chikamu chechipiri chinotadzisa miganho yezviyo uye kukura zviyo, nekudaro inowedzera tembiricha yekudziya.
Kamuri tembiricha michina yekuenzanisa enzanisa Kana iyo yekudziya yekushisa pa1200】, kugutsikana kunosvika kukosha kwakanyanya. MaElongation inoderera neyekuwedzera tembiricha inowedzera. Akashatiswa pa1500 ℃, uye denderedzwa rayo rakangoenzana ne zero. Kugadziriswa kweLELOLD YOLOLBDEUM WILE yakafanana neyako yakachena Molybdenum Wire, uye huwandu hwemagetsi hunosvika kuhukuru kana hwakawedzerwa pa1200 ℃. Uyezve denderedzwa rinoderera nekushisa kwekuwedzera. Iyo chete yakasiyana ndiyo nzira yekudzikisa inononoka. Kunyangwe elongation of Lanthanum-Diding Molybdenum Wire inoderedzwa mushure mekunze pa1200 ℃, ma elongation yakakwira kupfuura yakachena molybdenum waya.
