Iko recrystallization tembiricha ye lanthanum-doped molybdenum waya yakakwirira kupfuura yakachena molybdenum waya, uye imhaka yekuti diki yeLa2O3 inogona kuvandudza zvimiro uye chimiro chemolybdenum waya.Kunze kwezvo, La2O3 yechipiri chikamu mhedzisiro inogona zvakare kuwedzera kamuri tembiricha simba re molybdenum waya uye kuvandudza tembiricha yekamuri brittleness mushure mekudzokororazve.
Recrystallization Temperature Kuenzanisa: Iyo microstructure yeyakachena molybdenum waya yakawedzerwa pa900 ℃ uye yakadzokororwa pa1000 ℃.Nekuwedzera kwekushisa kweannealing, recrystallization zviyo zvinowedzerawo, uye fibrous tissues inoderedza zvakanyanya.Kana tembiricha yekudziya yasvika 1200 ℃, waya yemolybdenum yakagadziridzwazve, uye chimiro chayo chemukati chinoratidza yunifomu yakaenzanirana tsanga dzakadzokororwa.Sezvo tembiricha inowedzera, tsanga yacho inokura zvisina kuenzana uye inoita sembesa dzakakora.Kana yakanyungudutswa pa1500 ℃, waya yemolybdenum iri nyore kutyora, uye chimiro chayo chinoratidza zviyo zvakakora zvakaenzana.Iyo fiber chimiro chelanthanum-doped molybdenum waya yakawedzerwa mushure mekunyudzwa pa1300 ℃, uye chimiro chakaita semazino chakaonekwa pamuganhu wefiber.Pa1400 ℃, zviyo zvakadzokororwa zvakaonekwa.Pa1500 ℃, kuumbwa kwefiber kwakadzikira zvakanyanya, uye chimiro chakagadziridzwa chakaonekwa pachena, uye zviyo zvakakura zvisina kuenzana.Iko recrystallization tembiricha ye lanthanum-doped molybdenum waya yakakwirira kupfuura iyo yakachena molybdenum waya, iyo inonyanya kukonzerwa nekuita kweLa2O3 yechipiri chikamu zvidimbu.Chikamu chechipiri cheLa2O3 chinotadzisa kutama kwemuganho wezviyo uye kukura kwezviyo, nekudaro kuwedzera tembiricha yerecrystallization.
Kamuri Tembiricha Mechanical Properties Kuenzanisa: Kurebesa kweyakachena molybdenum waya kunowedzera nekudziya kweanodziya kuwedzera.Kana tembiricha yeaneal pa1200 ℃, kureba kunosvika pakukosha kwepamusoro.Kurebesa kunodzikira nekupisa kweaneal kuchiwedzera.Yakaiswa pa1500 ℃, uye kureba kwayo kunenge kuenzana ne zero.Kurebesa kwewaya yeLa-doped molybdenum kwakafanana newaya yemolybdenum yakachena, uye mwero wekurebesa unosvika pakakwirira kana wanyudzwa pa1200 ℃.Uye ipapo elongation inoderera nekuwedzera kwekushisa.Iyo yakasiyana chete ndiyo chiyero chekudzikisa chinononoka.Kunyangwe kurebesa kwewaya yelanthanum-doped molybdenum kunodzikiswa mushure mekunyura pa1200 ℃, kurebesa kwacho kwakakwira kupfuura pure molybdenum waya.
