Qhov sib txawv ntawm Gr4 thiab Gr9 Titanium

1. Tshuaj lom neeg sib xyaw

Cov tub ntxhais sib txawv nyob hauv lawv cov ntsiab lus alloy, uas ncaj qha tsav lawv qhov kev ua tau zoo:

Qeb 4 Titanium: Cais raws li aKev lag luam ntshiab (CP) Titaniumqib. Nws muaj ntau dua los yog sib npaug rau 99.0% titanium los ntawm qhov hnyav, tsawg dua lossis sib npaug ntawm 0.015% hydrogen, tsawg dua los yog sib npaug rau 0.25% oxygen). Tsis muaj lub tswv yim aloying ntsiab (zoo li txhuas lossis vanadium) ntxiv.

Qib 9 Titanium: Hu ua tusTI-3AL-2.5V alloy(ib qho ze - titanium alloy). Nws yog ib qho kev ua kom txhob txwm ua rau titanium nrog ob lub ntsiab lus tseem ceeb: ~ 3% Qhov sib ntxiv ntawm al thiab V hloov nws lub zog thiab microstructured tau ntau.

2. Cov Khoom Siv Neeg Kho Tshuab

Kev ua lag luam mechanical yog qhov cuam tshuam ntau tshaj plaws rau kev siv tshuab tsim khoom, tshwj xeeb hauv lub zog thiab ductility:

Ntiag tug	Qeb 4 titanium (CP)	Qib 9 Titanium (Ti-3al-2.5V)
Lub zog tensile	550-700 MPA (80-102 KSI)	760-930 MPa (110-135 KSI)
Paib lub zog	480-620 mpa (70-90 ksi)	690 - {860 MPa (100-125 KSI)
Elongation (hauv 25mm)	15-25% (qib siab)	10-18% (QUPERATE DUA, QUB LENG 4)
Hardness (Rockwell B)	80-90 hrb	95-105 hrb (tawv dua qib 4)

Qib 9 cov khoom siv alloy (AL, V) txhim kho nws lub zog thiab hat {

3. Corrosion Kuj

Ob feem qib pov thawj pom tias colosion zoo tshaj plaws, tab sis lawv cov kev ua tau zoo me ntsis hauv cov cheeb tsam siab:

Qib 4: Raws li ntshiab titanium, nws muajTshwj kev txiav txim siab corrosion tsis kamNyob rau hauv kev ua siab phem heev, suav nrog seawater, Chlorides, dilute acid (dilute), thiab nitric acid. Nws cov kev huv minimizes microstration teeb meem uas tuaj yeem ua rau corrosion, ua rau nws zoo tagnrho rau cov ntawv thov kev ruaj khov.

Qeb 9: Thaum tseem muaj corrosion - tiv taus tsawg dua nyob rau hauv qee qhov kev mob hnyav (piv txwv li cov pa roj ntsha Txawm li cas los xij, qhov kev lag luam no tsis lees paub rau feem ntau kev lag luam, thiab qib 9 nyob deb dua corrosion {} {tiv taus ntau dua li ntau cov hlau nplaum lossis alloys txhuas.

4. Cua sov kuj

Thaum tshav kub kub ua haujlwm (muaj peev xwm khaws tau lub zog ntawm cov chaw kub siab) txawv vim muaj kev faib tawm:

Qib 4: Ntshiab titanium khaws lub zog tsim nyog txog ~ 315℃(600℃f). Tshaj li no qhov kub no, nws lub tensile lub zog tshaj tawm sai sai, thiab nws yuav oxidize ntau dua. Nws tsis pom zoo rau kev siv tas mus li hauv high-} qhov kub siv.

Qeb 9: Ntxiv ntawm txhuas (uas ci rau lub titanium crystal qauv) txhim kho nws cov cua sov ua kom zoo. Nws tuaj yeem tswj hwm cov qauv kev sib raug zoo txog ~ 400℃(750℃f) -}} pa taws kub thiab txias).

5. Muaj peev xwm thiab tshuabsab

Cov khoom no cuam tshuam rau kev tsim khoom yooj yim:

Muaj meej:

Qib 4: Kev ua siab loj ua rau nwsYooj yim rau daim ntawvNtawm cov txheej txheem xws li txias dov, khoov, stamping, lossis kev kos duab sib sib zog nqus. Nws feem ntau yog siv rau cov khoom siv uas yuav tsum muaj cov duab (piv txwv li, nyias-}} Cov pa hluav taws xob ntoo, kev cog phom kho, kev kho mob kev kho mob).

Qeb 9: Kev daws teeb meem nruab nrab txhais tau tias nws yog tsim tau tab sis yuav tsum tau siv zog ntau lossis kev kho mob (kev kho cua sov) thaum ua kom tsis txhob tawg. Nws yog tsawg dua rau ultra - cov duab sib xyaw tab sis ua haujlwm zoo rau cov ntu (piv txwv li, cov khoom siv).

Luam ntawv:

Ob qib tau txiav txim siab "nyuaj rau lub tshuab" (titanium qhov thermal tsawg thermal ua rau cov cuab yeej kub Qeb 9 lub zog hardness nce thev khoom hnav, uas xav tau cov cuab yeej tshwj xeeb lossis qeeb dua machining ceev.

6. Cov ntawv thov raug

Lawv cov khoom ntiag tug tsav cov teeb meem sib txawv:

Qeb 4 Kev Siv: Ua ntej corrosion tsis kam, ductility, thiab biocompatibility:

Kev Kho Mob: Kev Cog Lus (lub duav khoom, cov txha caj qaum) thiab kev phais hniav) thiab kev phais cov ntaub ntawv (biocompigble nrog tib neeg cov ntaub so ntswg).

Tshuaj lom neeg: tso tsheb hlau luam, kav dej, thiab li qub rau kev siv cov kua corrosive.

Tubrog nkoj: seaterater {{{- cua txias sib pauv thiab cov chaw sib dhos.

Qib 9 Daim Ntawv Thov: Ua ntej muaj zog muaj zog - {{1} Txoj kev nyhav nti thiab nruab nrab kub tiv:

Aerospace: hydraulic kab, roj hlab, thiab cov txheej txheem txheej txheem (tshuav hluav taws xob muaj zog thiab lub teeb hnyav).

Roj & Roj: Downhole tubing thiab Wellhead Cheebtsam (tiv taus corrosion thiab ntsuas kub nruab nrab).

Automotive: High - Kev nqus dej lossis lub teeb yuag (rau tsheb sib tw (rau tsheb sib tw lossis hluav taws xob).
