Kev tsom xam cov khoom siv thiab cov qauv txheej txheem
1. Tshuaj lom neeg sib xyaw ua ke thiab cov khoom siv lub cev
TA8 titanium alloy belongs rau + hom DuPleX Alloy, thiab nws cov lus sib xyaw ua raws li ASTM B336 tus qauv.
Cov khoom xyaw tseem ceeb: TI 98.5% lossis siab dua, AL (5%), {}}}. 3% lossis tsawg dua, c 0.1% lossis tsawg dua).
Cov cuab yeej kho tshuab: ntom ntom 4.43G /M³ciav, Elasted State), thiab tuaj yeem ncav cuag 1000MPA tom qab kev laus, elongation ntau dua los yog sib npaug rau 10%.
2. Kev sib piv ntawm cov qauv hauv tsev thiab thoob ntiaj teb
American Txuj Ci: Ams 4901m stipulates tias qhov kub thiab txias rau kev daws teeb meem, thiab tuav lub sijhawm ntawm 1 teev rau txhua 25mm).
Tus Qauv Suav: GB / t 3621-2011 yuav tsum tau hais tias sab saud yog 940 degree tshaj li cov astm qauv kom tsis txhob muaj ntau yam ntawm cov theem.
Kev tswj kom zoo ntawm cov txheej txheem kev kho cua sov
1. Annealing Txheej Txheem: Kev nyuaj siab nyem thiab microstructure homogenization
Parameter ntau: {800-900 Â degree × 30-60} feeb, cua txias thiab tom qab cua txias.
Muaj nuj nqi: tshem tawm txias ua haujlwm ntxhov siab, ua kom cov nplej (grain loj hauv Astm qib} 0}}}}}
2. Ntshav kev kho mob: theem kev cai tswj thiab kev ua haujlwm kom ua tau
Kev daws qhov kub kub: {{1000-1040 degree × 1h (tau martensitic ', tau txais cov martensitic', txhim kho cov plastent (elongation ntau ntxiv rau 15%).
Ob chav daws cov tshuaj kho: 950 degree × 1h (cua txias) {2}}}}}}} degree ua tau zoo, nws lub voj voog kev ua haujlwm tau nce siab txog 30%.
3. Kev laus ua haujlwm: Cov cai tswj cov txheej txheem ntawm theem nag lossis daus
Cov kev laus: {480-650 degree rau {} ₂}) muaj zog ntxiv, thiab lub zog tensile nce rau {3}} mpa.
Tau kawm tiav: 550 degree × 2h {2}}}}}}} × degree corbor × 6Hcp ntawm 28Mpa /MPa√m.
Cov txheej txheem kev sib cav thiab tawg hauv cov thev naus laus zis tseem ceeb
1. Qib intergranular corrosion rhiab
Mechanism: kev txhawb nqa ntawm V caij ntawm cov ciaj ciam txhuv nplej ua rau xaiv cov kev sib cais. Lub ntsiab tm {2}} 177 tus qauv xav tau hais tias qhov hnyav poob nyob rau hauv {1}} teev ntsev txau tsawg dua 0.5mg / cm².
Kev daws:
Ntxiv 0. {{{}}. 3% pd (Palladium Microalloying) txo tus nqi xeb rau 1/10 ntawm thawj.
Ob-theem annaling tau saws: 750 degree × 2h {}}} {kom ua feem ntawm theem ntawm cov ciaj ciam nplej> 85%.
2. Synergistic optimization ntawm kev kho cua sov thiab ua haujlwm txias
Mob khaub thuas cov kab ke: deformation ntawm txhua lub pass 8-12%, tag nrho cov kev sib luag tsawg dua los yog sib npaug ntawm 70%}}} dhau.
Piv txwv li: ib qho kev lag luam roj uas tawg ntau ntxiv ntawm Ta8 Capillary los ntawm 150MPA los ntawm cov txheej txheem ntawm "cov kev daws teeb meem ntawm"}}}}}}}}}}}}} kev laus ".
Kev Lag Luam Kev Lag Luam thiab Xaiv Xaiv
1. Ntiaj Teb Nqe Hauv 2025
Cov lus hais thoob ntiaj teb: {{28-32 hackrars / kg (tub rog tub rog European), nce ntxiv 18% piv rau 2023.
Cov nqi hauv tsev lag luam: {220-260 Yuan / Kg (National Tub Rog Tub Rog GJB). Cuam tshuam los ntawm cov nyiaj se yuav txo qis hauv RCEP, kev yuav khoom ntawm Asia Yav Qab Teb Asia tau nce los ntawm 40% xyoo.
2. Kev kho ntawm kev xaiv tsis to taub
Kev ua txhaum cai 1: Tsis pom qhov tsis pom kev siab-muaj zog. Txoj kev txheej txheem yuav tsum raug xaiv raws li thaj chaw pabcuam. Piv txwv li, rau cov kav dej chemical, corrosion kuj yuav tsum tau muab ua ntej dhau lub zog.
Kev tsis tseeb 2: Tsis pub lwm tus sib txawv hauv cov ntawv pov thawj. AS9100 Aviation-Cov khoom pov thawj yuav tsum tau ntxiv raws li cov beta chaw nrhiav kom tau txais ntawm Ams 4908.
Xaus thiab xam pom ntawm cov tshuab pem hauv ntej
1. Cov lus pom zoo ua tiav:
Aerospace: Kev daws ntawm 1020 Degree + Laus ntawm 550 degree, nrog rau kev pom zoo heev muaj zog / Vineity.
Kev kho mob kho mob: Cov khoom siv kho mob ob zaug + micro-arc oxidation Degure Kho, biocompatibility mus rau iso {2}} txheem.
2. Cov Qauv Txheej Txheem:
Qhov kev thov ntawm Ta8 hmoov (nrog rau cov particle loj ntawm {1}} μm) rau kev tsim ntxiv, thiab kev lag luam loj yuav tsum tau ntau dua 1.5 billion Yuan hauv 2025.
Nyob rau hauv daim teb ntawm hydrogen zog cia thiab tsheb thauj mus los, kev tshawb fawb thiab kev tiv thaiv ultra-nyias-nyias-this-puttleness tau ua lub ntsiab lus tseem ceeb ntawm kev sib tawg.
