Qhov txawv ntawm Gr3 thiab Gr5 Titanium- kev paub

1. Kev faib tawm & tus kheej

Qib 3 Titanium: Belongs rauKev Lag Luam Ntshiab Titanium (Cp Ti) family (ASTM Grade 1–4). It contains >99% titanium, nrog tsuas yog cov nqi ntawm impurities (piv txwv li, oxygen, hlau) los kho cov khoom tseem ceeb. Nws cov kev ua tau raug txiav txim siab los ntawm kev coj dawb huv ntawm titanium thiab me me impurity cov ntsiab lus.

Qeb 5 Titanium: Cais raws li a+ titanium alloy, nrog kev lag luam - kev tsim qauvTI-6AL-4V(Lub ntsiab lus nws muaj ~ 6% aluminium thiab ~ 4% vanadium, nrog cov seem yog titanium). Qhov sib ntxiv ntawm txhuas (txhawb cov theem) thiab Vanadium (ruaj khov rau theem) thiab cov khoom siv hluav taws xob, ua rau nws muaj zog dua li cov qib ntshiab titanium.

2. Tshuaj lom neeg sib xyaw

Cov ntsiab lus tseem ceeb ntawm cov lus dag nyob rau hauv lub xub ntiag ntawm alloy cov khoom nyob rau qib 5, thaum qib 3 ntawm cov ntshiab titanium nrog tsawg heev impurities.

Khoom	Tseem tivthaiv	Qhov tseem ceeb alloying / impurity ntsiab
Qib 3 Titanium	Titanium (ti)	Tsawg dua los yog sib luag rau 0.3% hlau (fe), tsawg dua los yog sib npaug rau 0.08% carbon (c), tsawg dua lossis sib npaug ntawm 0.015% hydrogen (h)
Qeb 5 Titanium	Titanium (ti)	5.5-6.75% Aluminium (al), 3.5-4.5% Vanadium (qis dua lossis sib npaug lossis sib npaug lossis sib npaug

3. Cov Khoom Siv Kho Tshuab

Qhov no yog qhov sib txawv tshaj plaws rau cov ntawv thov kev kawm, tshwj xeeb tshaj yog nyob rau hauv lub zog {{}} muaj cov xwm txheej:

Ntiag tug	Qib 3 Titanium (Annealed)	Qib 5 Titanium (Annealed)	Tus yuam sij
Paib lub zog	380-480 MPa (55,000-70,000 PSI)	{{0860 - 930 MPa (125,000 PSI)	Qeb 5 yog ~ 2x muaj zog tshaj tawm lub zog; Nws tiv taus extraformation zoo dua.
Lub zog tensile	480-550 mpa (70,000-80,000 PSI)	900-1,000 MPA (130,000-145,000 PSI)	Qeb 5 lub tensile lub zog yog ~ 1.8-2x siab dua; Nws tuaj yeem tiv thaiv ntau dua rub cov rog ua ntej tawg.
Ductility (% elongation)	20–25%	10–15%	Qeb 3 yog ntau dua coo (yooj yim dua khoov, ncab, lossis daim ntawv) dua qib 5.
Hardness (HB)	150-180 HB	300-350 hb	Qib 5 yog qhov nyuaj npaum li cas (tawm tsam hnav / indentation zoo dua) vim muaj kev sib dhos.
Ceev	4.51 g / cm³	4.43 G /M³	Yuav luag txhua tus (ob lub teeb ci, ~ 60% lub ntom ntawm cov hlau).

4. Corrosion Kuj

Ob qho xwm txheej ua rau muaj kev tiv thaiv corrosion zoo, tab sis lawv cov peev xwm sib txawv los ntawm ib puag ncig:

Qib 3 Titanium: MuajSuperior Generic corrosion tsis kamHauv cov me rau ib puag ncig me me (xws li, dej hiav txwv, dilute acids, huab cua atmether). Nws cov ntshiab titanium matrix ua ib co ntom, ruaj khov txheej txheem (tio₂) uas txwv tsis pub muaj tshuaj lom neeg lossis cov tub rog "ntshiab" yog qhov tseem ceeb.

Qeb 5 Titanium: Muajzoo corrosion tsis kamNyob rau hauv feem ntau ib puag ncig (piv txwv li, aerospace ruels, firiological kua), tab sis yog tsis tshua tiv taus me ntsis (piv txwv li cov accolentrated ntau li sulfuric acid). Nws txoj kev ua lag luam corrosion yog ib qho kev lag luam - tawm rau kev siv zog ua kom zoo rau cov kev xaiv ntau rau feem ntau rau kev xaiv cov tshuaj heev.

5. Ua & Fabrication

Lawv cov txheej txheem sib txawv vim muaj zog thiab ductility kawg li:

Qib 3 Titanium: Yooj yim dua rau fabricate. Nws lub siab siab tso cai rauTxias ua haujlwm(piv txwv li, dov, khoov, kos duab) thiabvuam(Nrog rau tsawg kawg kev pheej hmoo ntawm kev tawg) tsis muaj ua ntej / tshaj tawm - kev kho cua sov. Nws tseem tshuab ntau dua li qib 5, txo cov cuab yeej hnav.

Qeb 5 Titanium: Nyuaj rau txheej txheem. Nws lub zog siab thiab qis dua ductility xav tauKub Ua Haujlwm(Ua ntawm nce qhov kub, ~ 800-900 degree) rau kev sib sau, ua haujlwm txias txias yuav ua rau tawg. Vuam xav tau meej tswj (piv txwv li, Argon Shielding, post- Weld kev kho cua sov) kom tsis txhob brittleness sov. Machining tseem nyuaj dua (kev hnav siab ntau, cov cuab yeej siv ceev ceev) thiab yuav tsum tau cov cuab yeej tshwj xeeb (piv txwv li, carbide ntxig).

6. Daim Ntawv Thov Kev Cai

Lawv cov khoom tshwj xeeb lub hom phiaj txawv kev lag luam:

Qib 3 Titanium: Siv qhov twgCorrosion Kuj + Daim Ntawv Muaj Peev Xwmyog ua ntej tshaj ntawm ultra - siab} lub zog siab. Cov ntawv thov feem muaj xws li:

Cov khoom siv ua khoom siv tshuaj (piv txwv li, tso tsheb hlau luam, kav dej, li qub rau dilute acids).

Cov khoom siv marine (piv txwv li, Hull rasteners, kev hloov cua sov).

Cov cuab yeej kho mob (piv txwv li, kev phais cov cuab yeej, tsis - ntsaws {{bearing} cov kabmob cov kabmob).

Cov kws tsim txuj ci cladding (rau kev siv huab cua phem hauv kev hnyav hauv kev ua phem).

Qeb 5 Titanium: Dominates nyob rau hauvhigh - lub zog - lub teeb yuagCov ntawv thov. Cov siv sib xws li suav nrog:

Aerospace / eg, dav hlau tsaws iav, lub cav txheej txheem, thav duab qauv).

Automotive (piv txwv li, siab - kev ua haujlwm cav, kev sib tw lub tsheb).

Medical impants (piv txwv li, lub duav / lub hauv caug hloov, Kev cog hniav -}}}}}}}}}}}}}}}}}}}}}} kov lub zog nrog biocompatibility).

Cov khoom siv kis las (piv txwv li, lub tsheb kauj vab kauj vab, Golf Club Hau).
