Lub npe "inconel" yog aTrademarkAmeslikas tau sau npe los ntawm Asmeskas lub tuam txhabLub tuam txhab Nickel thoob ntiaj teb (Inco){{0- Tam sim no ib feem ntawm Vale Sa, Kev Sib Tw Thoob Ntiaj Teb thiab Hlau Cortral Corporation. Lo lus yog PortManteau sib txuas ntawm lub tuam txhab npe thiab cov khoom lag luam ntawm cov khoom tseem ceeb:
Cov lus ua ntej "Inco -" ncaj qha nyiaj los ntawm "International Nickel tuam txhab," Highlighting lub keeb kwm.
Cov Txiab "{-}}}}}}}} Hais txog kev siv" Nickel "(Qhov hais txog cov khoom siv Nickel {}}} raws li muaj pes tsawg-.
Ua ntej siv nyob rau hauv thaum ntxov xyoo pua 20, lub npe tau tsim kom paub qhov txawv lub tuam txhab siab {} Chromium Superalloys los ntawm lwm cov hlau thiab alloys. Sij hawm dhau los, "Inconel" tau dhau los ua lub ntsej muag zoo {4} Xyuas cov npe ntawm cov supalloys, txawm tias yog cov tswv cuab ntawm cov lag luam tau hloov pauv.
Inconel alloys tau siv dav hauv Aerospace, lub zog, tshuaj lom neeg, thiab marine kev lag luam vim lawv cov khoom lag luam zoo. Lawv cov ntsiab lus tseem ceeb muaj raws li hauv qab no:
Tshwj xeeb siab -} kub ua tau
Lawv tswj cov cuab yeej ruaj khov (lub zog, tawv) ntawm qhov kub thiab txias txog650-1200 ° C (1202-2192 ° F)Cov. Qhov no yog ntaus nqi rau lawv cov nag lossis daus - Cov Hluav Taws Xob Hluav Taws Xob Zoo Li Huab Cua Zoo Nkauj (EX '}} Cov Hluav Taws Xob Kub Kub, thiab cov chaw so kom sov.
Zoo tshaj corrosion thiab oxidation tsis kam
Kev nplua nuj hauv chromium (10-30%), npib tsib xee (50-70%), thiab lwm yam alloys, xws li, cr₂o₃, al₂o₃) rau saum npoo. Cov txheej no ua kom tsis txhob xeb los ntawm acids, alkalis, dej hiav txwv, cws {{{- kev pabcuam kub nyob rau hauv ib puag ncig muaj kev txom nyem.
Kev kho tshuab zoo heev muaj zog thiab qaug zog tsis kam
Los ntawm kev ua haujlwm hnyav, ua haujlwm txias, lossis kev kho cua sov, suav nrog lub zog siab tensile lub zog (600-1200 mpa) ntawm ob chav thiab nce qhov kub. Lawv kuj muaj kev ua kom muaj zog tsis kam, nrog cov tshuab cua sov uas tsis muaj kev ua tsis ua hauj lwm-}}}} Cov pa roj carks thiab cov hlab ntsha siab.
Zoo creep thiab kev ntxhov siab tsam tsis kam
Lawv muaj cov creep zoo heev (tiv taus mus rau qhov tsis txaus ntseeg nyob rau hauv ntev {}} kub ntxhov siab (muaj peev xwm ntxhov siab) thiab ntxhov siab} kev ntxhov siab). Qhov no ua rau lawv haum rau ntev - kev pab {}} lub neej cov khoom siv hauv lub hwj chim (piv txwv li cov kab mob nuclear) thiab aerospace.
Kev siv hluav taws xob daws tau cov qib muaj ntau haiv neeg
Muaj ntau cov qib tsis meej (piv txwv li, 600, 625, 718, 738, txhua tus ua kom cov kev xav tau. Piv txwv li, Inconel 625 zoo li hauv corrosion tsis kam, inconel 718 sib npaug ntawm lub zog thiab suav 7- kub creep tsis kam. Qhov kev sib tw no tso cai rau lawv kom tau raws li qhov yuav tsum muaj ntawm cov xwm txheej sib txawv.
Txawm hais tias lawv tau kev ua tau zoo, inconel alloys muaj qee qhov kev txwv uas txwv lawv daim ntawv thov hauv qee kis:
Kev siv ntau lawm thiab cov khoom siv
Lawv feem ntau tsim ntawm siab - tus nqi hlau me xws li npib tsib xee, chromium, molybdenum, thiab tungsten. Tus nqi khoom siv yog ntau dua li cov ntawm carbon hlau, stainless hlau, lossis txawm tias muaj necloys alloys alloys. Ib qho ntxiv, cov txheej txheem sib xyaw ua ke (piv txwv li kev kho mob cas, ua kom muaj kev kub ntxhov) ntxiv rau kev thov cua sov ntxiv lossis tsis yog}} tseem ceeb.
Pluag Machinility
Vim lawv lub zog siab, tawv tawv, thiab ua haujlwm hnyav ua luaj, inconel alloys yog qhov nyuaj rau tshuab. Thaum lub tshuab ua haujlwm, lawv tsim kom muaj kev kub ntau, ua rau cov khoom hnav sai, thiab tsim cov chips nyuaj uas nyuaj rau tawg. Cov cuab yeej tshwj xeeb (piv txwv li, cov cuab yeej carbide), txiav ceev, thiab cov roj nplua nyeem tawm, thiab lub sijhawm ntau dua machining thiab cov nqi.
Nyuaj weldability (rau qee qib)
Thaum qee qib (piv txwv li, inconel 625) muaj cov weldability zoo, ntau lub siab- Lub zog 718, 738) yog qhov dhau los tawg thaum lub sij hawm vuam. Qhov no yog vim lawv cov ntsiab lus siab zoo thiab rhiab rau kev ntxhov siab thermal. Nruj ua ntej pre- weld npaj (piv txwv li, tu, preheating {{13} {{13} {13} {13} {13} {13} {13} {13} {13} {13} {13} {13} {13} {
Siab ntom thiab qhov hnyav
Nrog qhov ntom ntom ntawm kwv yees li8.1-8.5 g / cm³(siab dua cov hlau ua rau cov hlau ~ 7.85 g / cm³ yog tus ua haujlwm hnyav. Hauv qhov hnyav -, cov cuab yeej siv hluav taws xob ua haujlwm, lawv cov khoom siv hluav taws xob zoo li cov khoom siv titanium lossis ntau ntxiv.
Kev ntxim nyiam rau qee hom corrosion hauv ib puag ncig
Txawm hais tias feem ntau corrosion - tiv taus, qee cov qib tsis muaj peev xwm raug kev txom nyem los ntawm cov teeb meem corrosion hauv kev mob heev. Piv txwv li, Inconel 600 yog nquag ua rau muaj kev ntxhov siab rau hauv qhov kev daws teeb meem ntawm chloride hauv chloride hauv chloride nyob rau hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride nyob rau hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride- noj haus huv.
