Dab tsi yog ti -} 6al-4V siv rau

1. Dab tsi yog ti-6al-4V siv rau?

Ti {- 6v (qib 5 titanium) yog qhov tseem ceeb tshaj plaws ntawm lub zog siab, muaj txiaj ntsig, corrosion tsis kam, thiab biocompatibility. Nws cov ntawv thov ncua kev lag luam ntau ntau, suav nrog:

Aerospace & aviation: Qhov loj tshaj plaws kawg -} siv sector. Nws yog siv los ua cov khoom tseem ceeb xws li cov dav hlau cav (cov kab ke tis / {

Kev Kho Mob thiab Kho Hniav: Tus staple nyob rau hauv cov khoom siv tau vim nws biocompatibility vim nws cov tshuaj tiv thaiv nrog tib neeg cov ntaub so ntswg) thiab corrosion tsis kam (tiv taus lub cev ntawm lub cev). Cov kev siv ntau yam suav nrog kev cog lus orthopedic (hip / lub hauv caug hloov, kev cog hniav qaum teb (cov teeb meem, cov cuab yeej siv hluav taws xob), thiab kev phais cov duab.

Automotive (High - kev ua haujlwm): Siv rau hauv tus nqi lossis sib tw tsheb rau cov khoom siv zoo li kev tso pa tawm, raug tshem tawm qhov twg pab txhim kho kev ua tau zoo thiab txo cov emissions.

Tubrog Ntxhais thiab Offshore: Tso rau hauv cov khoom siv roj av marine (cov khoom siv rau lub kaus mom, cov cuab yeej siv roj av, risers) vim nws tiv taus dej qab ntsev thiab ua haujlwm hydrocarbons.

Cov Khoom Siv Ua Si: Pom nyob rau hauv high - kawg iav xws li lub tsheb kauj vab, thiab caij ski qhwv ntsej muag thiab caij tsheb ua haujlwm kom txhim kho kev ua kis las.

2. Dab tsi yog cov tshuaj lom neeg muaj pes tsawg leeg ntawm Ti-6V-4V Titanium?

Lub npe "Ti-6V" ncaj qha cuam tshuam nws cov ntsiab lus tseem ceeb, nrog cov seem kev ua lag luam ntshiab (ntxiv rau trace impurities). Nws cov nominal tshuaj muaj pes tsawg leeg (los ntawm qhov hnyav) ua rau cov qauv zoo li ASTM B265 (rau cov hlau / cov ntawv qhia txog kev kho mob), thiab yog raws li hauv qab no:

Lub ntsiab	Nomall composition (hnyav%)	Lub luag hauj lwm
Titanium (ti)	Sib npaug (~ 89-90%)	Cov hlau, muab cov allloy txoj kev corrosion tiv taus.
Aluminium (AL)	5.5–6.75%	Ntxiv dag zog rau cov alloy los ntawm ruaj khov - titanium theem; Txhim kho cov neeg nkag.
Vanadium (V)	3.5–4.5%	Stabilizes lub - titanium theem; txhim kho kev sib luag thiab tawv; txo cov rhiab rau kev tawg txias.
Trace impurities *	Tsawg dua los yog sib npaug rau 0.15% (tag nrho)	Tswj kom tsis txhob muaj peev xwm tsis ruaj khov kho. Cov kev cuam tshuam tsis sib xws muaj xws li hlau (FE, tsawg dua los yog sib npaug ntawm 0.2%), cov pa roj ntsha (Oxy), thiab hydrogen (h, tsawg dua los yog sib npaug rau 0.015%).

Nco tseg: kev txwv tsis pub yuav sib txawv me ntsis (piv txwv li, stricter txwv rau kev kho mob--4V los xyuas kom meej biocompatibility).

3. Dab tsi yog cov khoom siv tshuab ntawm Ti-6AL-4V titanium?

Cov khoom siv mechanical ntawm Ti-6V-4V nyob ntawm seb nws hnyavTem Siab (Lub Xeev Kho Cua Sov)- Lub xeev feem ntau yogib qho tseem ceeb(muag muag, ductile, rau kev sib sau) thiabtov {-} kho thiab laus (sta)(cua sov -}} nrhiav rau lub zog siab tshaj plaws). Hauv qab no yog covCov chav raug - kub cov khoom sivRau ob lub tshuab siv dav dav, raws ASTM cov qauv (piv txwv li, ASTM B265 rau kev siv cov qauv kev tsim kho, ASTM F136 rau kev siv tshuaj kho):

Cov Cuab Yeej Cuab Yeej Cuab Yeej	Annealed Temper (Cov nqi raug)	Kev daws -} Kho & Laus (Sta) Temper (Cov nuj nqis)	Kev Ntsuas Cov Qauv Siv

Sta Turper kub tau nce lub zog (los ntawm ~ 20-30% vs.

TI-6AL-4V khaws cov khoom siv zoo ntawm cov tshuab ntsuas kub (mus txog ~ 400℃/ 752℃/ 752℃/ 752℃F); Saum toj no, lub zog tsis lees paub vim theem kev hloov pauv.

Txog kev kho mob kev mob, "ntxiv cov khoom siv qis dua (ELI)" Ntau dua li ntawm 0.13%) txhawm rau txhim kho kev nkees ua hauj lwm thiab biocompatibility.
