Molybdenum lanthanum alloy properties: Ndeupi musiyano uripo pakati pemolybdenum lanthanum (Mo-La) alloy neTZM molybdenum alloy?

Ndeupi musiyano uripo pakati pemolybdenum lanthanum (Mo-La) alloy neTZM molybdenum alloy?

Chii chinonzi molybdenum-lanthanum alloy? Molybdenum-lanthanum alloy is a alloy inoumbwa ne base metal molybdenum uye lanthanum trioxide iripo sezvimedu zvakapararira mumatrix. Zviri mukati meLa2O3 mune alloy kazhinji 0.5% ~ 5.0% (chikamu chezhinji). To

Kuburikidza nekutsvagisa pamusoro pekuita tembiricha yepamusoro uye chimiro chinoenderana chemolybdenum-lanthanum alloy uye TZM alloy pa1000 ~ 1800 ℃. Mhedzisiro yacho inoratidza kuti kana tembiricha yadzikira pane 1400 ℃, iyo molybdenum-lanthanum alloy ine yakakwira yakazara kuita kwesimba uye plastiki. Kana tembiricha yakakura kupfuura kana yakaenzana ne1400 ℃, simba rekusimba remolybdenum-lanthanum alloy rinodzikira, uye purasitiki yemolybdenum-lanthanum alloy inodererawo. Nekuwedzera kwekushisa kwekuyedza, simba rekusimba reTZM alloy rinodzikira, asi plasticity yeTZM molybdenum alloy inowedzera, zvinonyatsopesana nemolybdenum-lanthanum alloy.

Panguva imwecheteyo, ingave simba kana plastiki, TZM alloy inofananidzwa ne molybdenum-lanthanum alloy pane imwe tembiricha. Kucherechedzwa kweMicrostructure kunoratidza kuti aya maviri mamolybdenum alloys anotanga kuita recrystalline pa 1100 ℃ uye anoenderera kusvika 1550 ℃, uye tsanga dzadzo dzakadzokororwa dzinoratidza chimiro chakareba, chakasiyana neiyo equiaxed tsanga mune yakadzokororwa mamiriro e pure molybdenum.

1. Nhanganyaya kune molybdenum lanthanum alloy

Molybdenum lanthanum alloy, inozivikanwawo seyepamusoro tembiricha molybdenum, brand MoLa, inogadzirwa nemolybdenum doped ine diki diki yelanthanum trioxide (La2O3) zvidimbu kuita inonzi inonzi laminated fiber structure. Iyi yakakosha microstructure inogona kuramba yakagadzikana kunyangwe kune tembiricha yakakwira kusvika 2000 ° C. Naizvozvo, molybdenum-lanthanum oxide ine creep resistance kunyangwe pasi pemamiriro akanyanya ekushandiswa. Isu tinonyanya kugadzira akadai mamolybdenum alloys kuita akakwira-tembiricha yevira, senge vacuum yevira yekupisa nhovo, sintering uye annealing mabhoti, tambo dzakasungwa kana evaporator coils.

2. Zvakanakira zve molybdenum lanthanum alloy:

Higher recrystallization tembiricha;

Iyo elongated particle chimiro chinogona kuvandudza ductility;

Yakasimba oxidation kuramba;

Higher creep resistance.

3. Recrystallization tembiricha: 1400 ℃ ~ 1500 ℃.

4. Kusagadzikana kwe molybdenum-lanthanum alloy (chikamu: Ω*mm2/m)

tembiricha ℃	20	600	1000	1200	1400	1700	1800	1900	2000
Kugadzikana	0.054	0.205	0.314	0.374	0.435	0.506	0.525	0.558	0.571

5, Molybdenum lanthanum alloy kuumbwa
