Rare Earth Molybdenum Alloy

Tsis tshua muaj lub ntiaj teb molybdenum alloy thiab npaj txoj kev ntawd

Nws suav nrog molybdenum alloy hlau siv rau qhov chaw hauv cov qij tshwj xeeb thiab cov khoom siv hluav taws xob, kev ua haujlwm hlau txiav thiab cov cua sov nyob hauv cov kilns, thiab cov txheej txheem npaj.

Vim tias cov hlau refractory molybdenum muaj qhov kub thiab txias zog, zoo conductivity, thermal conductivity, tsis tshua muaj expansion coefficient, thiab yooj yim ntawm kev ua, molybdenum hlau yog dav siv nyob rau hauv tshwj xeeb qhov muag teev thiab hluav taws xob lub teeb khoom siv xws li tsheb tungsten halogen teeb, high-pressure sodium. teeb, teeb pom kev zoo tungsten halogen teeb, thiab hluav taws xob lub teeb khoom siv los tsim lub teeb hooks, cov tub ntxhais nyob ib ncig ntawm lub filament, qhia rods, txhuas hlau thiab yas brackets, thiab lwm yam. thiab siv los ua cua sov xaim rau hydrogen furnaces hauv kev lag luam kiln. Txawm li cas los xij, nyob rau hauv cov khoom uas muaj qhov kub thiab txias yuav tsum tau ua, xws li kub-kub lub teeb bracket hlau, high-temperature electric furnace (nyob rau hauv kev tiv thaiv roj los yog nqus tsev vacuum) cua sov lub ntsiab Cheebtsam xav tau molybdenum hlau kom muaj kev kub siab zoo, ntshiab molybdenum hlau. recrystallization kub tsuas yog 1000 ~ 1200 degree, yog li feem ntau brittleness thiab tawg, nws lub zog kub kub kuj tseem qis thiab yooj yim rau deform, deb ntawm kev ua raws li cov kev cai saum toj no. Qhov no yog vim lub fact tias cov recrystallization nplej loj hlob nyob rau lub sij hawm no thiab tsim ib tug equiaxial grain qauv tom qab recrystallization. Hauv kev lag luam hlau, qhov xav tau ntawm cov hlau txiav molybdenum hlau muaj lub zog siab, hnav tsis kam, tsis tshua muaj plasticity, lub neej ua haujlwm ntev, thiab lwm yam khoom, piv nrog cov ntshiab molybdenum hlau tsis muaj zog, tsis zoo hnav tsis kam, siab plasticity, luv luv kev pab cuam lub neej, tsis tuaj yeem ua tau raws li qhov xav tau ntawm cov neeg siv khoom hauv kev lag luam tshuab.

Lub ntiaj teb tsis tshua muaj molybdenum alloy nrog kev ua haujlwm zoo, lub zog tensile siab, siab recrystallization kub, muaj zog hnav tsis kam, txheej txheem yooj yim, tsis yooj yim rau khoov thiab nkig, siab tawm los, cov khoom zoo sib xws, thiab kev pab lub neej ntev.

Lub ntiaj teb tsis tshua muaj molybdenum alloy, tus yam ntxwv ntawm cov hlau ntawm cov hlau uas muaj La2O3 thiab Y2O3 ob lub ntiaj teb tsis tshua muaj oxides, ob lub ntiaj teb tsis tshua muaj oxides suav rau tag nrho qhov hnyav feem pua ​​​​ntawm cov hlau yog 0.4 feem pua ​​​​rau 1.{{ 7}} feem pua ​​, thiab qhov hnyav piv ntawm La2O3:Y2O3 yog 4:1.

Nws yog characterized los ntawm qhov tseeb hais tias cov txheej txheem kev npaj yog sequential

a. Ammonium dimolybdate ua raw khoom hydrogenation gas rau txo kom tau molybdenum dioxide;

b. Raws li kev tsim qauv ntawm hlau hlau La2O3 thiab Y2O3 ob lub ntiaj teb tsis tshua muaj oxides, yaj nrog nitric acid;

c. Molybdenum dioxide thiab La (NO3) 3, Y (NO3) 3 tov yog doped uniformly nyob rau hauv lub nqus tsev vacuum, thiab qhuav kom tau doped molybdenum dioxide hmoov;

d. Lub doped molybdenum dioxide yog txo los ntawm theem nrab hydrogen kom tau doped molybdenum hmoov;

e. Lub doped molybdenum hmoov yog nias los ntawm txias isostatic nias rau hauv lub ntiaj teb tsis tshua muaj doped molybdenum pas nrig;

f. Lub ntiaj teb tsis tshua muaj doped molybdenum pas nrig yog pre-sintered ntawm qhov kub ntawm 1250 degree rau 1 teev; ces sintered ntawm qhov kub ntawm 1900 degree rau 6 teev kom tau ib tug sintered molybdenum pas nrig;

g. Lub sintered doped molybdenum pas nrig yog qhib ntawm qhov kub ntawm 1650 degree; qhov thib ob dov dawb paug yog nqa tawm ntawm qhov kub ntawm 1250 degree kom tau txais ib qho dov molybdenum pas nrig;

h. Cov dov molybdenum pas nrig yog rub rau hauv ib lub phaj loj rau hauv ib lub xaim; Tom qab ntawd cov hlau rub tau khaws cia thiab muab tso rau ntawm qhov kub ntawm 1250 ± 50 ° C rau 30 min; Tom qab tshem tawm cov kev ntxhov siab sab hauv, nruab nrab disc yog rub kom tau Mo-La-Y tsawg lub ntiaj teb doped hlau.

Tsis tshua muaj lub ntiaj teb molybdenum alloy, muaj ob lub ntiaj teb tsis tshua muaj oxides, La2O3 thiab Y2O3; Piv nrog cov ntshiab molybdenum, qhov kub-txias kev ua tau zoo ntawm cov khoom yog qhov zoo, qhov kub thiab txias recrystallization yog siab, thiab nws yog 300 ~ 500 degree siab dua cov ntshiab molybdenum, uas muaj cov khoom zoo xws li siab zog, siab hnav tsis kam, tsis tshua muaj plasticity, thiab lub neej ua haujlwm ntev, thiab muaj ntau yam kev siv hauv kev lag luam machining.

Txoj kev npaj ntawm no, sib txawv ntawm cov txheej txheem kev tsim cov hmoov hlau metallurgy, yog ua nyob rau hauv molybdenum dioxide theem ntawm ob lub khob nqus tsev vacuum ziab kua-khoom doping, thiab tom qab ntawd nqa tawm ib qho kev txo qis los npaj binary tsawg lub ntiaj teb doped molybdenum hmoov, thiab tom qab ntawd npaj los ntawm nias, sintering, siab ua, thiab lwm yam txheej txheem los npaj cov specifications ntawm 0.5 ~ 0.8mmMo-La-Y tsawg ntiaj teb doped molybdenum hlau.

Cov ntaub ntawv raw yog pheej yig thiab yooj yim kom tau, thiab cov khoom npaj molybdenum xaim muaj lub zog tensile siab, muaj zog hnav tsis kam, txheej txheem yooj yim, tsis yooj yim rau khoov thiab nkig, muaj cov txiaj ntsig siab, zoo sib xws, thiab lub neej ua haujlwm ntev. Lub hauv paus yog ammonium dimolybdate, thiab cov additives La2O3 thiab Y2O3 siv yog pheej yig thiab tsis muaj teeb meem rau tus neeg teb xov tooj lub cev; Cov txheej txheem ntau lawm yog yooj yim los tswj, yooj yim rau kev khiav lag luam, muaj kev nyab xeeb thiab txhim khu kev qha, thiab tsis tas yuav tsum muaj kev nqis peev loj thiab kev hloov pauv ntawm cov cuab yeej siv, uas yog tsim rau cov khoom loj loj; Piv nrog rau txoj kev ua kua-kua doping thiab cov khoom siv-khoom doping txoj kev, kev faib tawm ntawm cov khoom sib txuas ntxiv hauv cov khoom sib xws, thiab cov khoom sib xws yog qhov zoo; Lub tshuab ua haujlwm siab siv yog ob qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob
