High-temperature alloy yog hais txog ib hom khoom siv hlau uas yog ua los ntawm hlau, cobalt, thiab npib tsib xee ua cov ntsiab lus matrix thiab fused nrog lwm cov hlau lossis cov hlau tsis yog hlau. Nws tuaj yeem ua haujlwm ntev ntawm qhov kub siab tshaj 600 degree thiab nyob rau hauv qee qhov kev ntxhov siab. Nws yog cov khoom siv tseem ceeb hauv kev lag luam aerospace, roj turbines, tsheb, nuclear fais fab, petrochemicals, thiab lwm yam.
1. Kev faib tawm
1. Los ntawm cov ntsiab lus:
Hlau-raws li high-temperature alloy: high-temperature alloy muaj xws li hlau, chromium, tungsten, molybdenum, thiab lwm yam, siv nyob rau hauv nruab nrab kub (600-850 degree) tej yam kev mob. Hlau-raws li alloys feem ntau yog siv nyob rau hauv qhov chaw ntawm lub cav nrog qis kev khiav hauj lwm kub, xws li turbine discs, casings, thiab shafts.
Nickel-raws li high-temperature alloy: high-temperature alloy tsim los ntawm nickel, chromium, molybdenum, thiab lwm yam, siv nyob rau hauv nruab nrab thiab siab kub (650-1000 degree) tej yam kev mob. Ntawm tag nrho cov high-temperature alloys, npib tsib xee-raws li high-temperature alloys muaj lub siab tshaj plaws kub-kub lub zog thiab yog dav siv nyob rau hauv lub tsim ntawm turbojet aircraft xyaw thiab kub tshaj qhov chaw ntawm ntau yam industrial gas turbines, xws li turbine hniav, qhia hniav, turbines, thiab lwm yam.
Cobalt-based high-temperature alloy: austenitic high-temperature alloy tsim los ntawm cobalt, chromium, tungsten, npib tsib xee, thiab lwm yam khoom, siv nyob rau hauv qhov kub thiab txias, nrog cov ntsiab lus cobalt ntawm 40% -65%, zoo castability thiab weldability, thiab feem ntau yog siv los ua cov ntaub ntawv qhia hniav. Vim muaj cov peev txheej cobalt tsawg, hom alloy no kim heev.
2. Kev faib tawm los ntawm cov txheej txheem tsim khoom: Nws tuaj yeem muab faib ua peb pawg: deformed high-temperature alloys, cam khwb cia high-temperature alloys, thiab hmoov metallurgy high-temperature alloys.
3. Kev faib tawm los ntawm txoj kev ntxiv dag zog: Nws feem ntau suav nrog plaub pawg: kev daws teeb meem ntxiv dag zog, nag lossis daus ntxiv, oxide dispersion ntxiv dag zog, thiab fiber ntau ntxiv zog.
2. Daim ntawv thov
High-temperature alloys yog dav siv nyob rau hauv cov tub ntxhais kub-kawg Cheebtsam ntawm aviation, aerospace engines, ships, thiab industrial gas turbines.
1. Aviation teb
High-temperature alloys tau siv nyob rau hauv aviation cav txij li thaum lawv yug los. Nyob rau hauv niaj hnub aviation xyaw, high-temperature alloy cov ntaub ntawv yog tsuas yog siv rau plaub loj kub-kawg Cheebtsam: combustion chambers, coj chambers, turbine hniav, thiab turbine disks. Tsis tas li ntawd, lawv kuj tau siv rau cov casings, rings, afterburners, thiab tail nozzles.
2. Cov khoom tseem ceeb ntawm cov roj turbines
Cov roj turbines tau siv dav hauv kev lag luam nkoj, hluav taws xob, petrochemicals, metallurgy, thiab lwm yam. Piv nrog rau cov cav aviation, cov roj turbines yuav tsum tau kub kub alloys kom muaj zog thermal corrosion thiab lub koom haum zoo stability ntxiv rau kev nkag siab zoo, qaug zog. lub zog, thiab plasticity. Yog li ntawd, high-temperature alloys yog cov tseem ceeb raw cov ntaub ntawv rau turbine hniav thiab qhia cov hniav nrog zoo heev ua productivity mechanical kev ua tau zoo, thiab ruaj khov lub koom haum, uas ncaj qha txiav txim seb lub roj turbine yuav ua hauj lwm zoo rau lub sij hawm ntev nyob rau hauv ib tug complex ua hauj lwm ib puag ncig.
3. Nuclear fais fab teb
High-temperature alloys rau nuclear fais fab nroj tsuag muaj xws li roj av cladding cov ntaub ntawv, cov khoom siv, thiab roj pas nrig positioning grids, high-temperature gas furnace heat exchangers, thiab lwm yam, uas yog nyuaj los hloov nrog lwm yam ntaub ntawv.
4. Lwm qhov chaw
High-temperature alloys kuj ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv pej xeem kev lag luam xws li hluav taws xob, petrochemicals, tsheb, metallurgy, thiab iav tsim.
