Molybdenum lanthanum alloy: Phapano ke efe lipakeng tsa motsoako oa molybdenum lanthanum (Mo-La) le TZM molybdenum alloy?

Phapano ke efe lipakeng tsa alloy ea molybdenum lanthanum (Mo-La) le TZM molybdenum alloy?

Molybdenum-lanthanum alloy ke eng? Molybdenum-lanthanum alloy ke motsoako o entsoeng ka tšepe ea motheo ea molybdenum le lanthanum trioxide e teng e le likaroloana tse qhalakaneng ka har’a matrix. Litaba tsa La2O3 ka alloy hangata ke 0.5% ~ 5.0% (karolo ea boima). Ho

Ka lipatlisiso mabapi le ts’ebetso e phahameng ea mocheso le sebopeho se lumellanang sa motsoako oa molybdenum-lanthanum le motsoako oa TZM ho 1000 ~ 1800 ℃. Liphetho li bonts’a hore ha mocheso o le tlase ho 1400 ℃, motsoako oa molybdenum-lanthanum o na le ts’ebetso e phahameng e pharalletseng ea matla le polasetiki. Ha mocheso o le moholo ho feta kapa o lekana le 1400 ℃, matla a tsitsitseng a motsoako oa molybdenum-lanthanum a fokotseha, ‘me polasetiki ea molybdenum-lanthanum alloy le eona ea fokotseha. Ka ho eketseha ha mocheso oa teko, matla a matla a motsoako oa TZM a fokotseha, empa polasetiki ea TZM molybdenum alloy ea eketseha, e leng se fapaneng hantle le motsoako oa molybdenum-lanthanum.

Ka nako e ts’oanang, ebang ke matla kapa polasetiki, motsoako oa TZM o bapisoa le motsoako oa molybdenum-lanthanum ka mocheso o tšoanang. Maikutlo a microstructure a bonts’a hore li-alloys tsena tse peli tsa molybdenum li qala ho tsosolosa ho 1100 ℃ ‘me li tsoela pele ho 1550 ℃,’ me lithollo tsa tsona tse tsosolositsoeng li bontša sebopeho se selelele, se fapaneng le lijo-thollo tse lekantsoeng boemong bo bocha ba molybdenum e hloekileng.

1. Kenyelletso ea molybdenum lanthanum alloy

Molybdenum lanthanum alloy, eo hape e tsejoang e le mocheso o phahameng oa molybdenum, brand MoLa, e entsoe ka molybdenum doped e nang le likaroloana tse nyenyane tsa lanthanum trioxide (La2O3) ho etsa seo ho thoeng ke laminated fiber structure. Microstructure ena e khethehileng e ka lula e tsitsitse le ha mocheso o fihla ho 2000 ° C. Ka hona, molybdenum-lanthanum oxide e na le khanyetso ea creep esita le tlas’a maemo a feteletseng a tšebeliso. Haholo-holo re sebetsana le li-alloys tse joalo tsa molybdenum likarolong tsa sebōpi se nang le mocheso o phahameng oa mocheso, joalo ka lithebe tsa mocheso oa vacuum, liketsoana tse sintering le tse koalang, lithapo tse holehileng kapa li-coil tsa mouoane.

2. Melemo ea molybdenum lanthanum alloy:

Mocheso o phahameng oa recrystallization;

Sebopeho sa likaroloana tse telele se ka ntlafatsa ductility;

khanyetso e matla ea oxidation;

Khanyetso e phahameng ea creep.

3. Recrystallization mocheso: 1400 ℃ ~ 1500 ℃.
