Rau cov ntawv thov kub siab heev,Inconel 718thiabInconel 625Muaj kev xav tias yog qhov feem ntau ntau yam thiab ua tau zoo tshaj plaws hauv tsev neeg, piv txwv li cov kev xaiv tsis zoo, thiab ib puag ncig lossis corrosion).
Inconel 718:
Ib nag lossis daus-tawv-haromium-chromium alloy ntxiv dag zog los ntawm niobium thiab molybdenum, nws txawj ua kom sov siab rau1,300℃f (704 degree)Cov. Nws qhov txiaj ntsig tseem ceeb yog tshwj xeeb cov neeg nkag (tsis kam mus rau qhov tsis muaj zog ntxiv) thiab muaj zog kub, txawm tias tom qab kev sib tw ntev. Nws tseem khaws cov oxidation zoo tsis kam thiab yog qhov zoo tagnrho, ua kom zoo tagnrho rau cov khoom siv xws li cov khoom siv hluav taws xob, foob pob hluav taws xob cav, thiab cov khoom siv hluav taws xob nuclear.
Inconel 625:
Kev daws teeb meem-tov-txhawb nqa alloy (tsis muaj kev kho cua sov kom muaj zog), nws ua rau muaj kev ntseeg tau rau1,800℃f (982 degree)Cov. Thaum nws muaj me ntsis qis dua lub zog qis dua incmel 718 ntawm kev kub ntxhov (600-800 Nws yog feem ntau siv nyob rau hauv rauv taws, lub dav hlau cav nkag siab, thiab cov khoom siv tshuaj lom neeg ua haujlwm ntawm cov cua sov heev.
Hais txog: inconel 617
Tsim rau Ultra-High Tights Kub Txog2,100℃f (1,150 degree), nws yog siv hauv cov ntawv thov tshwj xeeb xws li gasbine combustors thiab muaj cov chaw ua hluav taws xob uas ob lub kub kub thiab ua kom sov sov thiab ua kom sov siab. Txawm li cas los xij, nws yog tsawg dua versatile ntau dua 718 lossis 625 vim muaj tus nqi ntau dua thiab muaj kev lees paub tsawg.
Qhov ntsuas kub txwv ntawm inconel alloys sib txawv los ntawm qib, raws li lawv muaj zog thiab ua kom muaj zog ntawm cov hluav taws xob (daus Ntawm no yog qhov tseem ceeb Harbors:
Inconel 600: Mus txog1,800℃f (982 degree)rau lub sij hawm luv luv; Haum rau kev ntsuas kub siab-kub oxidation tiv taus tab sis nrog qis zog ntawm qhov kawg.
Inconel 625: Txhim khu kev qha txog1,800℃f (982 degree)rau kev siv tas mus li, nrog lub sij hawm luv-ntev txog2,000℃f (1,093 degree).
Inconel 718: Muaj txiaj ntsig txog1,300℃f (704 degree)Rau cov kev pabcuam ntev ntev, nrog rau hauv ib ntus1,600℃f (871 degree)ua tau yam tsis muaj qhov tseem ceeb degradation. Nws lub zog tseem nyob ruaj khov ntawm no vim yog gamma-prime (') thiab gamma-ob-thawj zaug (") precipitates uas ua tus tiv thaiv ntau.
Inconel 617: Tsim rau Ultra-siab kub, muaj kev pabcuam siab tshaj plaws2,100℃f (1,150 degree)Cov. Nws khaws lub zog thiab oxidation tiv taus txawm nyob hauv ib puag ncig nrog cov sulfur lossis carbon.
Inconel X-750: Ua tau zoo txog1,300℃f (704 degree)Tab sis tej zaum yuav plam lub zog saum toj no ntau vim li cas preagipate coarsening, txwv nws siv nyob rau hauv kev txhawb nqa huab cua sov piv rau 617 lossis 625.
Cov kev txwv no xav tias cov alloy yog raug rau cov huab cua lossis oxidizing ib puag ncig. Nyob rau hauv kev txo cov cua (piv txwv li, roj av thiab huab cua zoo nkauj), qhov kub thiab txias yuav qis dua vim muaj kev mob siab rau kev xeb.
Yog, zoo li txhua tus hlau, inconel alloys nthuav dav thaum rhuab, ib qho cuab yeej hu uaThermal nthuav davCov. Txawm li cas los xij, lawv cov cua sov nthuav feem ntau yog feem ntau qis dua cov hlau uas muaj qhov kub thiab txias dua li cov khoom siv kub hauv thermal cycling ib puag ncig.
Thermal Cov Qauv Tshaj Tawm:
Inconel alloys feem ntau muaj aLINEAR THERMAL PROVAL nthuav tawm coefficient() nyob rau hauv ntau ntawm11-14 × 10⁻⁶(6-8 × 10⁻⁶ 10 teev ntawm chav nyob nruab nrab ntawm chav nyob thiab 1,000℃(1,832℃f). Rau kev sib piv:
Carbon Steel: ~ 12 × 10⁻⁶
316 Stainless Hlau: ~ 16 × 10⁻⁶
Qhov kev nthuav dav no txhais tau hais tias cov khoom siv tsis zoo uas tsis muaj kev hloov pauv ntawm lub zog hluav taws xob (piv txwv li, hauv cov cua sov lossis ua kom sov dua).
Kev sib txawv los ntawm qib:
Piv txwv li, Inconel 625 muaj ib qho kev nthuav dav thermal ntawm ~ 12,8 × 1018 yog tsawg dua ntawm ~ 11.7 × 10 teev 10-100 degree). Qhov no ua rau 718 tshwj xeeb haum rau kev ua kom nruj-kev ua siab ntev rau cov khoom siv hloov pauv hloov chaw.
Inconel ua nthuav dav thaum rhuab, tab sis nws tswj kev nthuav kub thermal thiab kub-txhim khu kev txhim khu kev qha ntau dua ntau cov alloys hauv kev siv cua sov heev.
