Titanium Seamless Yeeb Nkab: Qhov zoo nyob rau hauv siab -Qhov kub thiab txias ib puag ncig

Titanium alloy seamless kav sawv ntsug nyob rau hauv siab heev - kub ua hauj lwm tej yam kev mob vim lawv multi-sib nqus kev ua tau zoo, tshwj xeeb tshaj yog qhia irreplaceable stability nyob rau hauv ib puag ncig tshaj 300 degree.

 

 

1. Kub Adaptability ntawm Mechanical Properties

Cov khoom siv ntawm titanium alloys hloov tsis tu ncua nrog qhov kub thiab txias: lawv muaj ob lub zog siab thiab qee qhov ductility ntawm chav sov; thaum lawv lub zog txo qis ntawm qhov kub thiab txias, ductility thiab toughness yog ho txhim kho.

 

Piv txwv li, qhov elongation thiab cuam tshuam toughness ntawm Gr1 wrought lag luam ntshiab titanium ntawm 600℃yog superior rau cov nyob rau hauv chav tsev kub; siab - kub titanium alloys xws li Ti-6242S tuav lub zog tsis pub tsawg tshaj 400MPa ntawm 500℃. Qhov sib npaug ntawm qhov sib npaug ntawm "lub zog thiab ductility" tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm ob qhov kev pabcuam siab -cov khoom siv kub kom tiv taus cov khoom thauj tam sim thiab hloov mus rau lub sijhawm ntev deformation.

 

2. Zoo heev Oxidation thiab Corrosion Resistance

High - kub oxidation thiab corrosion yog lub ntsiab ua rau tsis ua hauj lwm rau cov kav hlau. Titanium alloys tuaj yeem ua tiav ob qho kev tiv thaiv los ntawm kev tsim cov yeeb yaj kiab oxide ntom ntom rau saum npoo. Cov oxide zaj duab xis no tuaj yeem thaiv cov pa oxygen molecules, nrog rau qhov hnyav ntawm oxidation tsawg dua los yog sib npaug li 1mg / cm² nyob rau hauv qhov kev sim ntawm 600℃/ 100h, outperforming tsoos cov ntaub ntawv xws li stainless hlau. Lub caij no, oxide zaj duab xis tswj kev ruaj ntseg zoo nyob rau hauv siab -kub corrosive ib puag ncig.

 

Piv txwv li, Ti-0.2Pd cov kav dej muaj qhov corrosion tsawg dua lossis sib npaug ntawm 0.01mm / a hauv 98% sulfuric acid ib puag ncig ntawm 300℃thiab 15MPa, nrog lub neej tsim ntawm 20 xyoo. Tsis tas li ntawd, titanium alloy seamless kav yuav tiv taus kev nyuaj siab corrosion thiab intergranular corrosion nyob rau hauv complex ua hauj lwm tej yam kev mob xws li Cl⁻- muaj geothermal brine thiab high-temperature dej nyob rau hauv thawj lub voj ntawm nuclear fais fab nroj tsuag, uas qhia tsis tshua muaj zog ib puag ncig adaptability.

 

3. Zoo heev Creep Resistance

Creep yog hais txog cov yas deformation qeeb ntawm cov ntaub ntawv nyob rau hauv ntev - lub sij hawm siab - qhov kub thiab txias, uas ncaj qha txiav txim lub neej kev pab cuam ntawm cov kav dej. Gr5 + hom titanium alloy seamless kav dej tuaj yeem tswj tau qhov ruaj khov theem qis qis ntawm 650℃thiab 150MPa; tshwj xeeb siab -kub resistant alloys ua tau zoo dua.

 

Ti-6242S muaj qhov deformation tsawg dua lossis sib npaug li 0.2% nyob rau hauv qhov kev sim ntawm 500℃/ 100h, thiab Ti-1100 alloy kav muaj lub neej nkag siab ntau tshaj 100,000 teev nyob rau hauv qhov chaw boiler supercritical ntawm 650℃/ 25MPa.

 

Qhov zoo tshaj plaws creep kuj ntawm cov titanium alloys stems los ntawm kev thaiv cov nyhuv ntawm lawv / theem interfaces thiab niaj hnub grain qauv, uas yuav zoo inhibit dislocation plam thiab grain ciam diffusion ntawm kub.

 

Cov qib sib txawv ntawm cov kav dej titanium

 

 

Lub siab -kub kev ua tau zoo ntawm titanium alloy seamless kav yog ze ze rau cov khoom muaj pes tsawg leeg. Kev lag luam ntshiab titanium thiab alloy titanium ntxiv rau ib leeg hauv qhov siv tau thiab qhov xwm txheej:

 

Qib	High -Tsuas Ua Haujlwm Zoo	Siv tau qhov kub thiab txias	Daim ntawv thov
gr2,g 4	Zoo heev yooj yim corrosion kuj, ruaj khov lub zog ntawm nruab nrab thiab qis kub	Tsawg dua lossis sib npaug li 400 degree	Primary voj pipelines ntawm nuclear fais fab nroj tsuag, cov khoom siv tshuaj ib txwm siv
Ti-5Al-2.5Sn	Zoo kub qaug zog tsis kam, balanced ductility thiab toughness	Tsawg dua lossis sib npaug li 500 degree	Aero- cav kav, siab - kub exchangers
Ti-6242 S	Zoo creep kuj, siab zog tuav tus nqi	Tsawg dua lossis sib npaug li 550 degree	Geothermal fais fab fais fab kav dej, siab -siab reactors
TSI-1100	Aviation-qib siab-kub alloy, siab heev-kub tsis kam	Tsawg dua lossis sib npaug li 650 degree	Supercritical boilers, advanced aero- cav

 

Kev lag luam ntshiab titanium (Gr2, Gr1) muaj txiaj ntsig zoo thiab qhia tau tias kev ua haujlwm ruaj khov hauv nruab nrab - kub ua haujlwm hauv qab 400℃;

Titanium alloys optimize siab -kub kev ua tau zoo los ntawm kev ntxiv cov ntsiab lus xws li Al, Sn, thiab Mo. Ntawm lawv, aviation -qib Ti-}1100 muaj qhov ntsuas kub txog li 650 degree, dhau los ua cov khoom tseem ceeb hauv kev txiav txim siab xws li kev tsim hluav taws xob supercritical.

 

Qhov kev tsim qauv sib txawv no ua rau cov titanium alloy seamless kav los npog tag nrho cov kev xav tau ntawm kev ua haujlwm los ntawm cov pa mus rau qhov kub thiab txias.

 

 

Lub siab -kev ua haujlwm kub ntawm titanium alloy seamless kav dej tau raug soj ntsuam xyuas hauv ntau qhov chaw tseem ceeb, ua rau lawv nyiam cov khoom siv rau kev ua haujlwm hnyav:

 

Nyob rau hauv lub zog teb, Ti-6242S seamless kav tau daws qhov teeb meem ntawm kev yooj yim tawg ntawm cov kav dej ib txwm siv nyob rau hauv high-temperature brine ua hauj lwm tej yam kev mob nyob rau hauv geothermal fais fab nroj tsuag;

 

Ti-1100 precision kav yog siv rau supercritical fais fab kis tau tus mob, combining lub teeb yuag zoo nrog ntev - lub sij hawm stability. Hauv kev lag luam tshuaj, Ti-0.2Pd cov kav dej tau ua tiav 20 xyoo ntawm cov teeb meem-kev pabcuam dawb hauv qhov kub thiab txias, siab-siab, thiab corrosive ib puag ncig;

 

Ti-3Al-2.5V cov kav dej tuab ua tau raws li cov qauv ntawm sulfide kev nyuaj siab corrosion, ua kom muaj kev nyab xeeb ntawm kev ua haujlwm roj thiab roj. Nyob rau hauv nuclear fais fab nroj tsuag, Gr2 titanium kav nrog tsawg neutron absorption cross-section yog siv nyob rau hauv thawj lub voj high-temperature dej system, thiab lawv corrosion kuj thiab structural stability yog ncaj qha cuam tshuam rau kev ua hauj lwm kev nyab xeeb ntawm nuclear fais fab nroj tsuag.
