Nimonic 81 Alloy Bar (UNS N06002|W.Nr. 2.4665)
Khoom Taw Qhia
Nimonic 81 alloy feem ntau yog npib tsib xee-raws li alloy muaj kwv yees li Bal Ni, 30% Cr, 1.8% Ti, 0.9% Al, thiab kab kawm. Nimonic 81 tau tsim los tiv taus ntev -kev pabcuam ntawm qhov kub ntawm 850-870℃.
Nws lub zog loj tshaj plaws yog tsis nyob rau hauv nws qhov hardness ntawm chav tsev kub, tab sis nyob rau hauv nws lub peev xwm los tuav lub zog zoo txawm tias thaum tshav kub kub mus rau ib tug liab - kub lub xeev, thiab tiv taus oxidation thiab corrosion ntawm high - ceev combustion gases. Yog li ntawd, nws yog cov khoom siv tseem ceeb siv hauv cov roj turbine qhia vanes, aircraft cav combustion chambers, thiab sib tw cav tso li qub.
Kev Qhia Txog Kev Muag Khoom thiab Cov Qauv Kev Lag Luam
1. Qib thiab Standard Requirements yog Fundamentals:
Common Trademark: Nimonic 81 (qhov no yog thawj lub npe ntawm Cov Hlau Tshwj Xeeb, tam sim no lub npe nrov hauv kev lag luam). Qee cov neeg siv khoom kuj hu nws Alloy 81|UNS N06002|W.Nr. 2.4665, etc.
Cov qauv sib xws: Txawm hais tias nws tsis muaj ib qho tshwj xeeb GB lossis ASTM tus lej tshwj xeeb xws li 304 stainless hlau, AMS 5861 (daim ntawv / sawb) lossis cov chaw tsim khoom cov qauv / cov neeg siv khoom kev pom zoo feem ntau yog hais txog thaum yuav khoom. Yog tias siv hauv thaj chaw aerospace, AMS cov qauv yuav tsum tau ua.
2. Customizable Loj:
Round Bars: Alloy 81 muaj nyob rau hauv txoj kab uas hla ntawm φ1 txog φ500, tab sis thaum cov khoom muaj ntau thiab hauv Tshuag, φ20-φ100 feem ntau siv. Dhau li ntawm cov kev qhia tshwj xeeb, cov tuav nrog tuab tuab lossis nyias diameters yuav tsum tau ua cov txheej txheem nruj dua thiab kim dua. Feem ntau, cov khoom tsim tawm, tus nqi ua tiav, thiab pov tseg yuav tsum raug txiav txim siab, thiab qhov kawg nqe lus yuav txawv nyob ntawm seb koj xav tau dab tsi.
Tus me nyuam qhov xwm txheej: Bars feem ntau yog kub- ua hauj lwm + daws kho (dub nto los yog machined tiav), los yog txias - kos (rau siab precision).
Thov hu rau peb rau ib qho kev tsocai thiab cov ntaub ntawv ntau ntxiv.
Kev ua haujlwm nyuaj thiab cov ntsiab lus tseem ceeb
(Qhov no yog tus yuam sij rau txuag nyiaj)
Nimonic 81 alloy bar yog ib qho nyuaj - rau - cov khoom siv tshuab. Raws li peb cov neeg siv khoom tawm tswv yim, qhov kev txhawj xeeb loj tshaj plaws yog tau txais cov khoom lag luam uas tsis ua haujlwm zoo lossis muaj cov khoom seem siab. Peb tau hu xov tooj rau cov kws tshawb fawb txog kev lag luam hauv lub Hoobkas thiab kawm txog ob qho kev ua haujlwm hauv qab no thiab cov kev ntsuas sib raug zoo, vam tias yuav pab tau koj.
1. Machining (Tig, Milling, Drilling): Nimonic 81 alloy yog nplaum heev thiab "hardens" thaum machining.
Nyuaj: Cov khoom no dhau mus ua haujlwm hardening thaum machining. Machining yuav nyuaj zuj zus nrog txhua qhov dhau. Tsis tas li ntawd, nws cov thermal conductivity tsawg ua rau cov cua sov tuaj yeem ua rau ntawm ntug txiav, ua rau cov cuab yeej hnav sai.
Kev daws: Siv cov cuab yeej carbide nrog TiAlN txheej. Xyuas kom muaj qhov tob loj ntawm kev txiav kom tsis txhob muaj kev sib txhuam ntawm qhov chaw me me. Thaum kawg, thiab tseem ceeb tshaj, cia lub sij hawm txias txaus; siv lub siab -flow- tus nqi coolant los tiv thaiv overheating.
2. Vuam:
Nyuaj: Cov khoom rhiab heev rau kub tawg.
Kev Ua Haujlwm: Vuam yuav tsum tau ua hauv kev daws teeb meem -kho lub xeev. Cov khoom siv vuam vuam yuav tsum sib haum (feem ntau vuam hlau ntawm tib cov khoom), thiab TIG vuam yuav tsum tau siv. Qhov saum npoo yuav tsum huv thiab tsis muaj roj ua ntej vuam.

Kev ceeb toom tshwj xeeb: Cov ntaub ntawv online rau Nimonic 81 alloy tuav yuav sib txawv, feem ntau yog vim qhov sib txawv ntawm "kev xa khoom". Yog tias koj tab tom yuav cov khoom siv los ua kom sov thiab kho koj tus kheej, nco ntsoov xyuas nrog tus neeg muag khoom seb qhov kev xa khoom puas yog kev daws teeb meem - kho lossis ua ntej - muaj zog.
Cov ntsiab lus tseem ceeb ntawm kev soj ntsuam zoo
Cov txheej txheem lees paub yog qhov tseem ceeb ntawm kev xa khoom tsim nyog.
- Daim ntawv qhia tshuaj muaj pes tsawg leeg lossis cov duab / yeeb yaj kiab: Spectroscopic tsom xam daim ntawv qhia rau Alloy 81. Peb feem ntau tsom mus rau seb cov ntsiab lus ntawm Cr (30%), Ti (1.8%), thiab Al (0.9%) yog nyob rau hauv qhov kev pom zoo.
- Mechanical Property Report: Feem ntau, chav -kub tensile cov ntaub ntawv. Yog tias siv nyob rau hauv qhov chaw siab - qhov kub thiab txias, nws yuav tsum tau kuaj xyuas seb tus neeg muag khoom puas tuaj yeem muab siab -kub creep lossis siab - cov ntaub ntawv kub tensile (txawm tias qhov no feem ntau yuav tsum tau kuaj ntxiv).
- Metallographic qauv: Tshawb xyuas cov qoob loo loj thiab muaj cov precipitates. Rau Nimonic 81, zoo -cov qauv ua tau zoo muab kev ua haujlwm zoo dua rau kev qaug zog thiab feem ntau yog siv los ntawm cov neeg siv khoom uas xav tau kev ua haujlwm qaug zog.
Cov lus qhia kom tsis txhob muaj kev ntxhov siab:
Tsis txhob saib tus nqi xwb. Nimonic 81 yog qhov nyuaj rau smelt. Yog tias tus nqi qis qis, nws zoo li yuav raug cuav li Nimonic 75 lossis txawm tias zoo tib yam stainless hlau. Nco ntsoov kos npe rau daim ntawv cog lus kev lag luam thaum yuav khoom, qhia meej meej txog kev tswj ntau yam rau qis - melting- cov ntsiab lus (xws li Pb, Sn, Bi), vim qhov no cuam tshuam ncaj qha rau kub - kev ua haujlwm thiab kev pabcuam lub neej.
