1. Cov tshuaj lom neeg muaj pes tsawg leeg 57ni {-}}} 19.5cr-13.5Co sib haum rau ib tus paub zoo superalloy. Dab tsi yog nws lub npe, thiab dab tsi yog qhov tseem ceeb ntawm Ams5544L kev qhia tshwj xeeb?
Qhov sib xyaw 57ni {-}}}}}}}}}}}}}}}}}}}}}}}}}}}} Qhov no yog ib npib tsib xee {{} chromium {}}}}}}}}}}}}}}}}}}}}}} pa-molybdenum zog thiab oxidation tsis kam.
Ams5544L Cov lus qhia tshwj xeeb yog qhov tseem ceeb raws li nws txhais tau qhov tshwj xeeb rau cov ntawv no hauv daim ntawv, sawb, thiab phaj. Qhov qauv "L" feem ntau qhia kev tswj hwm tshwj xeeb ntawm cov tshuaj lom neeg, feem ntau cov ntsiab lus hauv Weldability thiab tseem tswj hwm siab thaum tseem ua kom muaj siab} cov khoom kub.
Tseem ceeb ntawm Ams5544L:
Governs Melting Txheej Txheem: Nws ua kom cov khoom siv tau tsim los ntawm kev siv hluav taws xob ntau melting lossis nqus av induction melting. Qhov no ua kom muaj qhov siab - homogeneous cov khoom lag luam uas muaj cov khoom tsis zoo (O, H) thiab tsis xav tau cov kab.
Txhais cov metallurgical mob: tus qauv qhia meej cov khoom siv tau muab tso rau hauv kev daws anealed mob. Qhov kev kho cua sov no (feem ntau nyob ib ncig ntawm 1175 Degree F) tshem tawm theem theem nrab thiab carbides ua rau cov theem Austenitic thiab carrosity, thiab muaj peev xwm rau kev ua kom zoo nkauj.
Tuaj koom cov khoom: Nws teeb tsa cov khoom ntiag tug me me yam (vensile zog, tshem tawm lub zog, elongation) ntawm chav sov, kom muaj cov khoom siv kub sib xws thiab txhim khu kev qha.
2. Vim li cas yog cov txheej txheem melting xws li kev siv hluav taws xob melting (CEVM) lossis nqus plua plav (vim) cov ntawv thov no tshwj xeeb rau hauv aerospace?
Qhov yuav tsum tau rau cov txheej txheem melting ua ntej yog tsav los ntawm kev xav tau cov kev ua tau zoo ntawm kev ua haujlwm hauv aerospace thiab lwm yam siab {{}} ReiSbility kev lag luam. Lub hom phiaj tseem ceeb yog kom ua tiav qhov kawg cov qauv tshuaj thiab cov qauv zoo tshaj plaws.
Nqus tau los ntawm melting (vim): Qhov no feem ntau yog thawj kauj ruam. Melting nyob rau hauv lub tshuab nqus tsev tso cai rau kev tswj kom meej ntawm kev tswj cov pa roj hmab thiab tshem tawm cov pa roj teeb zoo li oxygen thiab nitrogen. Nws ua rau muaj siab - zoo electrode rau kauj ruam tom ntej.
Kev siv tau hluav taws xob hluav taws xob melting (CEVM lossis var): Lub Vim electrode yog remelted nyob rau hauv lub nqus dej arc rauv. Cov txheej txheem no muaj:
Kev ua haujlwm zoo dua: Nws tshem tawm lub "cais" ib txwm muaj kev cuam tshuam, ua kom muaj zog ntxiv dag zog rau (CR, MO) yog kev faib tawm uniformly. Qhov no tseem ceeb heev rau kev ua tau zoo ib yam ntawm daim nyias nyias.
Txo cov kev suav nrog: Lub tshuab nqus tsev thiab tswj tau cov solidification tso cai tsis tso cai rau tsis ntab, ua rau cov hlau nqus tsev huv si nrog cov chaw muaj peev xwm tsawg rau kev pib ua haujlwm.
Txhim kho lub suab nrov: nws ua rau muaj kev sib tw nrog cov khoom sib txawv, cov lus qhia tsis pub muaj cov qauv zoo, tsis muaj siab ntsws thiab pob taws nruab nrab.
Rau hastelloy X cov ntawv siv hauv lub dav hlau cav sib txuas, cais cov pa hluav taws xob, lossis suav nrog ua kom muaj zog sab hauv Lub VIM + CEVM cov txheej txheem yog qhov tsis - Hais tau zoo theem zoo los tiv thaiv kev ua tsis tiav.
3. Nyob rau hauv ib lub roj av tshuab, muaj dab tsi los ntawm Ams5544L Sheet / phaj yog qhov tseem ceeb, thiab dab tsi cov khoom ua rau muaj kev sib cais no rau lawv?
Hastelloy X (Ams5544L) yog cov khoom siv kub ntawm cov khoom kub ntawm cov khoom siv kub, tshwj xeeb hauv cov khoom siv uas yuav tsum muaj zog ua kom muaj zog thiab ib puag ncig tsis kam.
Cov khoom tseem ceeb:
Combusction xas (commustors): cov khoom siv uas roj sib xyaw thiab hlawv ntawm huab cua sov heev.
Cov Cheebtsam tom qab: cov ntu uas ua kom dhau cov roj cua sov siab tshaj plaws.
Kev hloov pauv DUTS: Coj cov roj kub kub los ntawm cov tshuab sib txuas rau cov ntu turbine.
Indispensable Cov Zog Ntawm Hastelloy X:
Tshwj xeeb oxidation tsis kam: lub siab chromium cov ntsiab lus (~ 22%) ua rau muaj kev cuam tshuam ntawm oxidizing kev kub ntxhov ntawm kev kub ntxhov ntawm kev kub siab txog 1175℃(2150℃f).
High-Temperature Strength: The solid-solution strengthening from Molybdenum (~9%) and Cobalt provides excellent creep strength-resistance to slow deformation under stress-allowing these thin-walled sheet metal components to maintain their structural integrity.
Zoo thermal fermal nkees ua kom tsis kam: cov alloy tuaj yeem tiv thaiv cov kev ntxhov siab rov qab los ntawm cav pib}} kev voj voog tsis muaj cracking.
Formancion thiab Weldability: Hauv kev daws -}}} ecealed mob teev los ntawm cov duab ua ke thiab yooj yim welded los tsim cov khoom sib xyaw no.
4. Qhov "corrosion - resistant" nam ntawm no npib tsib xee no itface ua si sab nraum aerospace?
Thaum muaj kev tshaib plab rau siab - kub kev ua tau zoo, cov nyiaj ntsuab siab thiab cov roj mab ntawm cov txheej txheem tsim tshuaj lom neeg siv tshuaj lom neeg.
Cov ntsiab lus tsis kam txo cov kua qaub: tus ~ 9% Molybdenum cov ntsiab lus muab cov khoom siv hluav taws xob muaj zog los txo cov acid (h ₂pephoric acid (h omo₄), tshwj xeeb thaum lawv muaj oxidizing impurities.
Kuj zoo li cov kab mob shloside zoo li cov tshuaj tua kab mob tawv nqaij
Tuav ntawm Halogens thiab catalyst ntws: nws yog siv nyob rau hauv cov khoom siv rau kev ua haujlwm hauv fluoriness (piv txwv li cov khoom siv fluoriness) lossis hauv cov khoom siv fluoriness) lossis hauv cov roj av petrochemical thiab hydroprocessing units.
Nyob rau hauv cov ntsiab lus no, ib lub phaj ams.544L tej zaum yuav siv rau fabricate cov cua sov ua kom muaj zog, reactor uas yuav tsum tau tiv thaiv kev kub siab, siab, thiab ib qho chaw huv si.
5. Dab tsi yog qhov kev sib tw tseem ceeb thiab kev coj ua zoo tshaj plaws hauv vuam thiab kev sib sau sau ntawv ams5544l sheet hlau Cheebtsam?
Kev tsim kho cov ntsiab lus nrog qhov siab - performanceults alloy yuav tsum muaj cov txheej txheem uas khaws cia nws corrosion tsis kam thiab tiv thaiv tsis xws luag.
Vuam cov nyom & Cov Kev Ua Haujlwm Zoo:
Kev sib tw: kev ntxim nyiam rau weld kub tawg (solidification tawg) vim nws cov kab mob cais tawm thiab cais tawm {{{1} {} {} {
Cov kev coj ua zoo tshaj plaws:
Kev nyiam huv: Kev tu kom zoo nkauj heev kom tshem tawm txhua yam kev paug (cov leej faj, phosphorus, txhuas, roj).
Muab tub rog hlau: siv cov chaw ua haujlwm overalloy zoo li ernicrmo-2 lossis ernicrcomo-1 (hastelloy x thiab 617 hom filers) los txo kev ua tiav.
Tsawg cov cua sov tawm: siv cov hlua khi cov hlua khi, tswj kev kub ntxhov, thiab tsis txhob muaj weaving los txo cov tau weld pas dej khiav ua ke thiab cais.
Txoj kev cov kev cov nyom & kev coj ua zoo tshaj plaws:
Kev sib tw: cov ua haujlwm alloy - hashens sai thiab muaj lub zog siab ntawm chav tsev sov.
Cov kev coj ua zoo tshaj plaws:
Siv cov khoom siv annealed: txhua txoj kev tsim khoom yuav tsum tau ua rau cov khoom siv hauv kev daws hauv kev daws teeb meem {{}}} ent5544L).
Cov khoom siv muaj zog: Yuav tsum muaj zog ntau dua li tsim cov hlau tsis muaj.
Generial Bend Radii: Siv radii loj dua kom tsis txhob tawg.
Nruab nrab annaling: Rau kev ua haujlwm hnyav, ib qho kev daws teeb meem hauv nruab nrab, ib qho kev daws teeb meem hauv nruab nrab yuav tsum tau rov ua dua thiab rho tawm haujlwm - haj attlening kev ntxhov siab.
Ua raws li cov kev coj ua ua kom ntseeg tau tias cov sib xyaw ua ke khaws cia cov khoom tshwj xeeb uas Hastelloy X tau xaiv.
