5J1480 precision alloy 5J1480 superalloy Hlau-nickel alloy Raws li cov ntsiab lus matrix, nws tuaj yeem muab faib ua hlau-raws li superalloy, nickel-based superalloy thiab cobalt-based superalloy. Raws li cov txheej txheem kev npaj, nws tuaj yeem muab faib ua deformed superalloy, casting superalloy thiab hmoov metallurgy superalloy. Raws li txoj kev ntxiv dag zog, muaj cov tshuaj tiv thaiv kom muaj zog, hom nag lossis daus ntxiv, oxide dispersion ntxiv dag zog hom thiab fiber ntau ntxiv hom. High-temperature alloys yog tsuas yog siv nyob rau hauv kev tsim khoom ntawm high-temperature Cheebtsam xws li turbine hniav, qhia vanes, turbine discs, high-pressure compressor discs thiab combustion chambers rau aviation, naval thiab industrial gas turbines, thiab kuj yog siv nyob rau hauv lub tsim. ntawm aerospace tsheb, foob pob ua ntxaij cav, nuclear reactors, petrochemical cov cuab yeej thiab Coal conversion thiab lwm yam khoom siv zog conversion.

cov ntaub ntawv thov

5J1480 thermal bimetal 5J1480 precision alloy 5J1480 superalloy hlau-nickel alloy superalloy yog hais txog ib yam khoom siv hlau raws li hlau, npib tsib xee thiab cobalt, uas tuaj yeem ua haujlwm ntev ntawm qhov kub siab tshaj 600 ℃ thiab nyob rau hauv ib qho kev ntxhov siab; thiab muaj lub zog siab kub zoo heev, zoo oxidation tsis kam thiab corrosion kuj, zoo qaug zog kev ua tau zoo, tawg toughness thiab lwm yam khoom siv. Lub superalloy yog ib qho qauv austenite, uas muaj cov qauv zoo ruaj khov thiab kev pabcuam kev ntseeg tau ntawm ntau qhov kub thiab txias.

Raws li cov yam ntxwv ntawm kev ua tau zoo saum toj no, thiab qib siab ntawm alloying ntawm superalloys, tseem hu ua "super alloys", yog cov khoom tseem ceeb uas siv dav hauv aviation, aerospace, roj av, tshuaj lom neeg kev lag luam, thiab nkoj. Raws li cov ntsiab lus matrix, superalloys tau muab faib ua hlau-raws li, nickel-based, cobalt-based thiab lwm yam superalloys. Qhov kev pab cuam kub ntawm cov hlau-raws li high-temperature alloys feem ntau tuaj yeem ncav cuag 750 ~ 780 ° C. Rau cov khoom siv cua sov uas siv rau qhov kub siab dua, cov nickel-based thiab refractory hlau-raws li alloys yog siv. Nickel-based superalloys nyob hauv txoj haujlwm tshwj xeeb thiab tseem ceeb hauv tag nrho cov teb ntawm superalloys. Lawv tau dav siv los tsim qhov kub tshaj plaws ntawm aviation dav hlau tshuab thiab ntau yam muaj roj turbines. Yog tias lub zog ruaj khov ntawm 150MPA-100H siv raws li tus qauv, qhov kub siab tshaj plaws uas cov nickel alloys tuaj yeem tiv taus yog> 1100 ° C, thaum cov nickel alloys yog li 950 ° C, thiab cov hlau alloys yog <850 ° C, uas yog , npib tsib xee-raws li alloys yog sib npaug siab dua los ntawm 150 ° C mus txog 250 ° C. Yog li ntawd tib neeg hu ua cov nickel alloy lub plawv ntawm lub cav. Tam sim no, nyob rau hauv cov tshuab siab heev, nickel alloys account rau ib nrab ntawm tag nrho qhov hnyav. Tsis yog tsuas yog turbine blades thiab combustion chambers, tab sis kuj turbine disks thiab txawm tias cov theem kawg ntawm compressor hniav tau pib siv cov nickel alloys. Piv nrog rau cov hlau alloys, qhov zoo ntawm cov nickel alloys yog: siab dua ua haujlwm kub, ruaj khov qauv, tsis tshua muaj teeb meem theem thiab siab tiv thaiv oxidation thiab corrosion. Piv nrog rau cobalt alloys, nickel alloys tuaj yeem ua haujlwm nyob rau hauv qhov kub thiab txias, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ntawm cov hniav txav.

5J1480 thermal bimetal 5J1480 precision alloy 5J1480 superalloy Hlau-nickel alloy Cov saum toj no-hais zoo ntawm nickel alloy muaj feem xyuam rau qee yam ntawm nws cov khoom zoo heev. Nickel yog lub ntsej muag-centered cubic qauv nrog heev

ruaj khov, tsis muaj allotropic transformation ntawm chav tsev kub mus rau qhov kub siab; qhov no tseem ceeb heev rau kev xaiv raws li cov khoom siv matrix. Nws paub zoo tias cov qauv austenitic muaj cov txiaj ntsig zoo ntawm cov qauv ferrite.

Nickel muaj tshuaj lom neeg ruaj khov, tsis tshua muaj oxidizes qis dua 500 degrees, thiab tsis cuam tshuam los ntawm huab cua sov, dej thiab qee cov dej ntsev ntsev hauv tsev kawm ntawv kub. Nickel dissolves maj mam hauv sulfuric acid thiab hydrochloric acid, tab sis sai sai hauv nitric acid.

Nickel muaj peev xwm alloying zoo, thiab txawm tias ntxiv ntau tshaj kaum hom alloying ntsiab tsis tshwm sim teeb meem theem, uas muaj peev xwm ua tau rau kev txhim kho ntau yam khoom ntawm nickel.

Txawm hais tias cov khoom siv ntawm cov nickel ntshiab tsis muaj zog, nws cov plasticity zoo heev, tshwj xeeb tshaj yog thaum kub kub, plasticity tsis hloov ntau.

Nta thiab siv: nruab nrab kub rhiab heev thiab siab resistivity. Thermal sensor nyob rau hauv nruab nrab kub ntsuas thiab tsis siv neeg tswj cov cuab yeej
