| Qeb 12 | Ti {-0. 3% mo -0. 8% ni | Txhim kho Weldability thiab high-kub ruaj khov (piv txwv li, kev ua yeeb yam). |
| Qib 16 & 17 | Ti {-0. {04-0. 08% pd | Cov variants ntawm Qib 2 & 1 nrog PD rau superior corrosion tsis kam. |
(B) titanium alloys
| Teem nqi | Alloy Muaj pes tsawg | Cov yam ntxwv tseem ceeb |
|---|---|---|
| Qeb 5 (Ti -6 ib -4 v) | 6% al, 4% v | Feem ntau dav siv titanium alloy; Lub zog siab, aerospace, kev cuam tshuam kev kho mob. |
| Qeb 9 (ti -3 al -2. 5v) | 3% al, 2.5% v | Txhim Kho Ductility thiab Qib 5, siv hauv tubing (hydraulic, tsheb kauj vab thav duab). |
| Qeb 23 (ti -6 al -4 v eli) | 6% al, 4% v (ntxiv cov interstitials) | Cov Kws Kho Mob-Qib, zoo dua Fracture Tougness rau kev phais mob. |
| Qib 29 (Ti -6 al -4 v-ru) | 6% al, 4% v, {0. 1% ru | Txhim kho corrosion tsis kam rau offshore roj & roj apps. |
2. Cov yam ntxwv tseem ceeb ntawm Astm B265 Titanium
Siab zog-rau-qhov hnyav piv: Muaj zog dua li cov hlau tab sis ~ 45% sib zog.
Corrosion Kuj: Advitally rau Saltwater, chlorine, acids, thiab alkalis.
Biocompatibility: Qeb 1, 2, 5, thiab 23 tau txais kev pom zoo FDA-tau pom zoo rau kev cog hniav kho mob.
Kub tiv thaiv: Khaws lub zog ntawm kev kub siab (txog ~ 600 degree rau qee cov alloys).
Weldability & formability: CP qib ({1-4) yog yooj yim weldable; Alloys zoo li Qib 5 xav tau cov txuj ci tshwj xeeb.
3. Cov Ntawv Thov Tib Neeg
| Kev ua hauj lwm | Cov Ntawv Thov |
|---|---|
| Ib tug tub rog | Cov tawv cua khov kho, Cheebtsam lub cav, tsaws iav (qib 5). |
| Ntawm kev kho mob | Cov pob txha pob txha, kev ntsuas cov twj, kev kho hniav (qib 1, 2, 5, 23). |
| Kev Lag Luam | Cov kev pauv hluav taws xob tshav kub, reactors, cov piping (qib 2, 7, 12). |
| Tubrog Ntxhais thiab Offshore | Cov khoom siv hauv qab no, nkoj Hulls, Desalination Nroj Tsuag (Qib 2, 29). |
| Automotive | High-inticting pa tshuab, txuas cov pas nrig sib txuas (qib 5). |
| Lub zog | Nuclear cov thawv ntim khoom siv, cov raj xa khoom geothermal (qib 7, 12). |
4. Kev tsim qauv & kev ua
Kub Rolling vs. Txias Zov:
Kub-rolled daim hlau / cov ntawv txheeb yog siv hauv kev siv cov kev siv zog siab.
Txias-dov strips muab kev ua kom nruj thiab cov chaw smoother.
Kev Kho Cua Sov: Qee cov alloys (piv txwv li, qib 5) Yuav tsum muaj anealing rau cov khoom muaj txiaj ntsig zoo.
Cov kev xaiv ua tiav: Polished, pickled, lossis blasted chaw nyob ntawm daim ntawv thov.
5. Kev sib piv nrog lwm cov qauv
ASTM F67: Npog CP Titanium rau kev phais mob.
ASTM F136: Qhia txog cov kws kho mob-qib-qib-qib 1}} al -4 v eli (qib 23).
Ams 4911: Aerospace-tshwj xeeb version ntawm Ti -6 al {2}} v.
