Qhov sib txawv ntawm qib 2 thiab qib 3 titanium

Titanium qib 2 thiab qib 3 yog ob leeg txwv tsis pubCov neeg lag luam ntshiab titanium (cp ti)thiab qhia cov yam ntxwv tseem ceeb xws li corrosion zoo tshaj plaws (muab tau los ntawm ruaj khov titable titable) thiab qis ntom ntom (~ 4.51 g / cm³). Txawm li cas los xij, lawv txawv nyob rau hauv cov tshuaj muaj tshuaj, cov neeg kho tshuab, thiab cov kev siv raug, thiab cov ntsiab lus raug rau hauv cov ntsiab lus tsis huv (tshwj xeeb tshaj yog cov pa oxygen (tshwj xeeb tshaj yog cov pa oxygen). Hauv qab no yog cov ncauj lus kom ntxaws ntawm lawv qhov sib txawv tseem ceeb:

1. Tshuaj lom neeg sib xyaw

Thawj qhov sib txawv ntawm lubOxygen Cov Ntsiab Lus(Ib qho ntsiab lus tseem ceeb impurity uas cuam tshuam lub zog thiab duction) thiab sib txawv me me hauv lwm cov kab lus. Ob qib kawm muaj ntau dua los yog sib npaug rau 99% titanium raws li cov hlau, uas tsis muaj cov khoom siv anoying.

Lub caij (los ntawm qhov hnyav, wt%)	Titanium Qib 2 (ASTM B265)	Titanium Qib 3 (ASTM B265)	Qhov tseem ceeb txhais tau
Cov pa (O)	0.10 – 0.18%	0.18 – 0.25%	Qib 3 muaj ~ 40% ntau dua oxygen, ncaj qha rau nws lub zog tab sis txo kev sib hwm.
Carbon (c)	Tsawg dua los yog sib npaug rau 0.08%	Tsawg dua los yog sib npaug rau 0.08%	Kev txwv zoo ib yam; tiv thaiv brittle carbide (TIC) tsim.
Hydrogen (H)	Tsawg dua los yog sib npaug rau 0.015%	Tsawg dua los yog sib npaug rau 0.015%	Nruj me ntsis tswj nyob rau hauv ob leeg kom zamHydrogen Clittlement(brittle crushing nyob rau hauv kev ntxhov siab).
Nitrogen (n)	Tsawg dua los yog sib npaug rau 0.03%	Tsawg dua los yog sib npaug rau 0.03%	Kev txwv zoo ib yam; Nitrogen txhawb lub zog tab sis yuav txo qis tawv yog tias muaj ntau dhau.
Hlau (FE)	Tsawg dua los yog sib npaug rau 0.30%	Tsawg dua los yog sib npaug rau 0.30%	Kev txwv zoo ib yam; Me hlau impurity me ntsis txhim kho muaj zog yam tsis muaj kev cuam tshuam loj corrosion.
Titanium (ti)	Sib npaug (ntau dua los yog sib npaug rau 99.0%)	Sib npaug (ntau dua los yog sib npaug rau 99.0%)	Luj hlau; paub cov tub ntxhais corrosion tsis kam.

2. Cov Khoom Siv Cov Khoom Siv (Annealed State)

Annealing (ua kev kho cua sov kom daws kev ntxhov siab thiab ua kom muaj kev ntxhov siab zoo rau ob qib. Lawv cov kev ua haujlwm ua rau txawv txawv, tsav los ntawm cov ntsiab lus oxygen:

Ntiag tug	Titanium Qib 2	Titanium Qib 3	Qhov tseem ceeb sib piv
Lub zog tensile	345 - 550 MPA (50,000 - 80,000 PSI)	480 - 620 MPA (70,000 - 90,000 PSI)	Qib 3 yog ~ 25-40% muaj zog nyob rau hauv lub zog tensile.
Paib lub zog	275 - 485 MPA (40,000 - 70,000 PSI)	370 - 485 MPa (54,000 - 70,000 PSI)	Qib 3 muaj 35-50% ntau dua cov txiaj ntsig lub zog (tsis kam mus rau deformation kev puas tsuaj).
Elongation (50 hli koob nyiam)	20 – 30%	15 – 25%	Qeb 2 yog ntau dua coo (yooj yim dua khoov, ncab, lossis daim ntawv) vim yog cov oxygen.
Hardness (Rockwell B)	~ 70 - 80 hrb	~ 80 - 90 hrb	Qib 3 yog qhov nyuaj me ntsis, kho kom haum nrog nws lub zog siab dua.

3. Daim qauv & tshuab luam ntawv

Titanium Qib 2: Hu ua "Workhorse" ntawm ntshiab Titanium, nws muajmuaj peev xwm ua tau zoo heevCov. Nws tuaj yeem yooj yim txias- ua haujlwm (piv txwv li, khoov, yob, stamping, stamping yam tsis muaj qhov tsis muaj kev pheej hmoo tsis muaj kev phom sij. Nws lub siab ductility tseem yooj yim dua li yooj yim rau hauv cov duab ua nyuaj (piv txwv li cov ntawv me me, me me}} txoj hlab khaub hlab).

Titanium Qib 3: Formability yogtswj kav{{0- tsis tseem ceeb rau qib 2 tab sis tseem muaj peev xwm ua tiav rau kev tsim cov kev tsim kho (piv txwv li, yooj yim dabtsi yog los yog extrusion). Cov ntsiab lus oxygen ntau dua ua rau nws stiffer; Kev ua haujlwm ntau dhau {- ua haujlwm yuav ua rau tawg, yog li nws feem ntau yuav tsum tau tswj kev ua (piv txwv li, nruab nrab analaling los rov ua dua destility).

Rau continity, ob qib kawm yog qhov nyuaj (titanium lub thermal tsawg thermal ua cov cuab yeej nyuaj ntxiv {} maj mam txiav ceev ceev lossis tsim qauv nyuaj.

4. Corrosion Kuj

Ob qho kev nthuav dav qibTshwj kev txiav txim siab corrosion tsis kamNyob rau hauv feem ntau ib puag ncig ib puag ncig, ua tsaug rau lawv cov ntshiab titanium matrix thiab tus kheej -} kho oxide zaj duab xis. Lawv ua tau zoo hauv:

Dej hiav txwv thiab cov tub rog ib puag ncig (resistays pitting thiab crevice corrosion).

Oxidizing cov kua qaub (piv txwv li, nitric acid) thiab nruab nrab / tsis muaj zog alkaline daws teeb meem.

Muaj chemical (piv txwv li, chlorides, sulfates).

Tsis muaj cov ntsiab lus sib txawv hauv kev xeb tawm tsam ntawm lawv -} Cov qib tsis huv hauv ob qho tib si ntawm cov oxide cov yeeb yaj kiab ruaj khov.

5. Cov ntawv thov raug

Lawv lub zog sib txawv - ductility sib npaug tsav tsheb sib txawv siv cov rooj plaub sib txawv
