1. Dab tsi yog cov yam ntxwv ntawm cov yam ntxwv thiab cov ntawv thov tseem ceeb ntawm GH4133 thiab GH4049 SUPERALLOYS?
GH4133 thiab GH4049 yog ob qho kev suav tshiab- txheem, precipitation {} {}}} raws supalloys. Thaum ob qho tib si yog tsim los rau high {6} kev ntxhov siab, lawv puas ua haujlwm hauv kev sib txawv thiab cov kev siv tshuab, tshwj xeeb hauv chav aerospace.
GH4133 (muaj qhov piv txwv rau inconel 718):
Characteristics: GH4133 is a nickel-chromium-iron-niobium alloy known for its excellent comprehensive properties. Nws cov yam ntxwv tseem ceeb suav nrog cov muaj zog ntau dua, ua kom qaug zog txog li 700℃{} {9- hnub nyoog tawg. Qhov no yog vim nws thawj zaug ntxiv dag zog rau theem, tus coherent gamma ob hom (''} ni₃nb, uas maj mam qeeb.
Thawj cov ntawv thov: nws yog ib tug workfors alloy siv nyob rau hauv qhov tseem ceeb tab sis tsis yog qhov kub tshaj plaws.
Aerospace: turbine disks, compressor hniav, ib ncig, thiab shaft inflines thiab roj tev.
Cov qauv sib xyaw: Bolts, fasteners, thiab siab - lub zog txheem qhov chaw hauv airframes.
Tubing daim ntawv thov: Siv rau high -}} h siab piping thiab manifolds hauv cav tshuab uas muaj zog thiab weldability yog qhov tseem ceeb.
GH4049 (ib qhov siab dua-} Performance alloy):
Cov yam ntxwv: Gh4049 yog qhov nyuaj ntxiv, chromium -}}}}}}} titanium muaj zog zog alloy. Nws yog tsim rau cov peev xwm kub siab thiab muaj zog tshaj Gh4133, feem ntau yog kev pabcuam hauv 800 {}}} 1740- 1740} 170}} Nws lub zog yog los ntawm cov feem ntau ntim ntawm gamma prime (') -ni₃ (al, ti) theem. Qhov no los nrog kev ua lag luam tawm: nws yog qhov nyuaj rau cov txheej txheem thiab WELD tshaj GH4133.
Thawj cov ntawv thov: Nws yog siv nyob rau hauv feem ntau xav tau, kev kub tshaj plaws ntawm lub cav.
Aerospace: turbine hniav, coj cov vanes, thiab kev sib txuas sib xyaw Chamber Cheebtsam.
Cov ntawv thov tubing: siv rau cov khoom sib xyaw xws li tom qab cov ntaub pua chaw, thiab lwm yam kev ua kom sov thiab ntau dua kev ua kom sov nyob ntawm qhov kub heev yog qhov tseem ceeb.
2. Yuav ua li cas cov txheej txheem dag zog ntawm Gh4133 thiab GH4049 sib txawv, thiab qhov no cuam tshuam li cas lawv cov kev ua?
Cov tub ntxhais sib txawv hauv lawv qhov kev ua tau zoo thiab cov txheej txheem dag nyob hauv lawv cov metallurgical ntxiv dag zog rau kev siv tshuab.
GH4133: Gamma ob npaug ntawm Prime ('') ntxiv dag zog
Mechanism: Thawj thawj zaug muaj peev xwm ntxiv dag zog hauv GH4133 yog lub cev {1} {{{{} ni₃nb theem. Cov theem no precipitates uniformly uniformly thoob plaws ntawm lub npib tsib xee thaum lub sijhawm kho mob kub (feem ntau nyob ib puag ncig 720 degree).
Kev cuam tshuam rau kev ua: '' 'theem muaj cov dej ntws qeeb los nag los siv rau' theem. Qhov no yog qhov zoo tshaj plaws rau vuam thiab cov ntaub sib dhos. Nws txhais tau tias cov alloy tsis tshua muaj kev phom sij rau "-}}}}}}} {weld {weld kev kho cua sov. Qhov no ua rau GH4133 tubing kuj yooj yim rau fabricate rau hauv cov tshuab complex.
GH4049: Gamma Prime (') muaj zog
Mechanism: Gh4049 tau ntxiv dag zog los ntawm cov feem ntau ntim ntawm lub ntsej muag {{1} Chaw Sau Cubic '{}} ni₃ (al, ti) theem. Qhov kev sib txuas lus sib xyaw no yog qhov ruaj khov thiab ua tau zoo heev ntawm kev tsis sib haum xeeb, muab kev cuam tshuam zoo dua {} kub lub zog thiab cov plaw ua haujlwm.
Kev cuam tshuam rau kev ua: cov theem pib sai sai. Qhov no ua rau muaj alloy heev dhau mus lim -} hnub nyoog tawg thaum lub sijhawm kho cua sov. Cov kev ntxhov siab uas muaj kev nyuaj siab los ntawm kev tsim lossis vuam vuam tuaj yeem ua ke nrog cov kev ntxhov siab los ntawm kev nyuaj siab, ua rau muaj kev sib tsoo. Yog li ntawd, vuam ghening ghex049 tubing muaj kev nyuaj siab heev thiab yuav tsum tau cov txheej txheem tshwj xeeb, thiab ntau zaus, nws yog zam rau cov qauv zoo rau cov qauv. Cheebtsam feem ntau siv hauv cam lossis wrought daim ntawv thiab koom nrog me nyuam.
3. Dab tsi yog qhov tseem ceeb ntawm kev siv GH4133 lub tubing nyob rau hauv siab- qhov siab} kev kub siab aurospace?
GH4133 lub tubing yog feem ntau xaiv rau high- qhov siab ntawm cov khoom uas muaj kev cia siab thiab kev nyab xeeb:
Tshwj xeeb muaj zog - rau - Lub zog muaj zog, nws tuaj yeem tiv thaiv huab ntawm cov roj, kua dej hauv cov kua dej hydraulic, lossis cua. Kev txo qhov hnyav yog qhov tsim qauv hauv Aerospace.
Superior Weldability thiab covricability: nws tsis kam mus lim {{0} {}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} Lub hnub nyoog tubular qauv siv tigh thiab laser vuam. Qhov no ua rau tsim kev tsim cov unricate manifolds, cov sib txuas, thiab kab uas yuav tsis yooj yim sua nrog cov supallable tsawg dua.
High fatigue resistance: Aerospace cov khoom sib xyaw yog kev sib txheeb tas li thiab lub siab voj voog. GH4133 Cov khoom ua pov thawj zoo heev - kev voj voog thiab qis {- lub neej ntev yam tsis muaj kev cuam tshuam ntev yam tsis muaj kev pib ua haujlwm ntev.
Zoo corrosion thiab oxidation tiv: cov ntsiab lus chromium muab qhov kub thiab txias rau kev ua haujlwm ntawm kev ua haujlwm ntawm kev ua tsis taus hauv lub cav Bay.
Qhov kev sib xyaw ua ke no ua rau GH4133 tubing ib txoj kev ntseeg tau thiab "zam txim" cov khoom siv rau cov engineers tsim kev lag luam tseem ceeb tsis yog ib qho kev xaiv.
4. Rau lub turbine ua kom muaj zog tshaj 900 degree, vim li cas thiaj yuav tau teev tseg GH4133?
Kev ua haujlwm yog lub txiav txim siab ua. Ntawm qhov kub tshaj 900 degree, cov peev txheej tseem ceeb ntawm GH4133 pib ua kom sai, ua rau nws tsis phim.
Kev ploj ntawm lub zog hauv GH4133: Qhov ntxiv dag zog '' theem hauv GH4133 yog qhov ntxim nyiam. Thaum raug rau qhov kub nyob sab saud muaj kwv yees li 750℃rau lub sijhawm ntev, nws nrawm nphom thiab tsis yog {- ni₃nb theem. Qhov kev hloov pauv no ua rau muaj kev mob siab rau lub zog thiab cov kab mob uas hu ua "tshaj {{}} kev laus." Lub raj gh4133 cov raj hauv qhov chaw no yuav nrawm deform thiab tawg hauv qab nws tus kheej hnyav thiab hnyav.
Khaws cia lub zog hauv GH4049: Qhov 'ntxiv dag zog rau theem hauv GH4049 yog qhov ruaj khov rau cov kub siab dua (li ~ 1000 degree). Nws coarsens ntau maj mam ntxiv, tso cai rau cov alloy los khaws qhov tseem ceeb ntawm nws lub zog thiab, qhov tseeb, nws cov kev pab cuam + service. Qhov no ua kom cov pa ua kom pom tseeb nws txoj kev ruaj khov ruaj khov thiab cov qauv kev ntseeg siab tshaj nws lub neej kev pabcuam xav tau.
Superior oxidation tsis kam: thaum ob lub alloys muaj chemium, feem ntau ua rau muaj kev ua pa ntau dua, yog qhov chaw ua hauj lwm tsis txaus ntseeg, qhov twg yog qhov chaw ua hauj lwm tsis txaus ntseeg rau qhov qis- qib alloy.
5. Dab tsi yog qhov tseem ceeb tswj hwm thiab soj ntsuam cov kauj ruam rau kev ua kom muaj kev ntseeg tau ntawm tubing ua los ntawm cov alloys?
Teb:
Muab qhov tseem ceeb ntawm lawv cov ntawv thov, tubing ua los ntawm GH4133 thiab GH4049 undergoes nyuaj tswj.
Tshuaj lom neeg cov khoom siv tshuaj lom neeg: siv kho qhov muag tawm ntawm kho qhov muag (OES) kom ntseeg tau tias cov txiv ntseej yog nyob rau hauv strumtures gho qauv kev qhia tshwj xeeb. Lw cov lus ua rau muaj kev phom sij rau cov haujlwm ua haujlwm lossis weldability (piv txwv li, PB, BI) yog tswj kom nruj.
Kev Ntsuam Xyuas Microstration:
C grain Kev txheeb xyuas loj: Cov khaub ncaws loj, cov khoom loj me me yog qhov tseem ceeb rau cov khoom siv zoo rau cov khoom siv thiab lub neej qaug zog. Qhov no yog soj ntsuam ib astm E112.
Incllusion Ntsuam Xyuas: Muaj cov tsis - nws muaj xim hlau (piv txwv li, cov neeg tuaj yeem ua raws li cov chaw ua haujlwm rau nkees.
Theem Ruaj Ntseg (rau GH4133): Cov tshev rau qhov muaj kev cuam tshuam ntev, xws li cov theem delta theem lossis laves theem, uas tuaj yeem txav cov khoom.
Tsis - Kev sim tshuaj (ndt):
Eddy kev sim tam sim no: Ua tau zoo rau kev kuaj xyuas nto thiab ze rau {}} nplaim npoo, tawg, thiab suav nrog tubular khoom.
Kev Kuaj Ultrasonic: Siv los tshawb xyuas cov kev ua tsis tiav sab hauv zoo li voids, suav nrog, lossis cov lamints. Caw Kaw Lus Ultrasonic Ntsuas (Aut) yog txheem rau high-}}} kev ncaj ncees tubing.
Zas kev sim tshuaj (PT): siv rau ntawm cov khoom tiav, tshwj xeeb tshaj yog nyob rau hauv thiab ib ncig ntawm weld a6 {0} breaking tsis xws luag.
Neeg kho tshuab thiab cov cuab yeej kuaj:
Tensile thiab Kev Ntsuas Xyuas: Cov ntawv xeem tau ua nyob rau hauv ob chav thiab nce qhov kub kom paub meej cov khoom siv yam tsawg kawg nkaus thiab lub neej tsis txaus ntseeg.
Kev kuaj Hardness: Siv raws li kev txheeb xyuas nrawm nrawm ntawm qhov tseeb ntawm kev kho cua sov.
Siab sim: Raws li qhov kawg ntawm lub cev, ua tiav cov tubrogular sib sau ua ke yog feem ntau raug rau hydrostatic lossis pneumatic siab sim kom ntseeg tau tias cov xau dej siab.
