1. Dab tsi yog Titanium Ti-6V-4V siv rau?

Ti {-} 6}}} 4v yog ib qho ntawm feem ntau muaj zog} rau-qhov hnyav piv, thiab cov xeb tawm tsam, thiab cov txheej txheem xeb, thiab txheej txheem. Nws cov ntawv thov Asmeskas Kev Lag Luam Kev Kawm Tau Zoo, nrog cov ntsiab lus tseem ceeb raws li hauv qab no:

(1) Aerospace & Aviation (loj tshaj daim ntawv thov sector)

Nov yog thawj daim teb rau Ti-6AL-4V, raws li nws qhov qis dua (~ 4.43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g /43 g / cmÃ

Airfram Cheebtsam: Fuselage thav ntawv, tis spars, thiab bulkheads - bearing qhov uas xav tau kev tawm tsam rau kev ua kom qaug zog thiab ua rau atmospheric corrosion.

Lub Cav Txheej Txheem: Compressor hniav, discs, thiab casings casings. Cov Alloy lub creep resistance (muaj peev xwm tiv taus deformation nyob rau hauv ntev-} Cov cua sov (txog li cas txog ~ 400 degrch) thiab cov neeg kho tshuab thauj khoom hauv cov pob tawb.

Tsaws Iav: Struts thiab nkhaus, uas xav tau ultra - lub zog tseem ceeb thiab cuam tshuam los txhawb lub dav hlau hnyav thaum lub nkoj, thiab ua haujlwm av.

(2) Kev Lag Luam & Kev Ua Tshuaj

TI-6AL-4V LUB ZOO NKAUJ COLROSTIONS RIGSANCE RESISTANCE (Vim Muaj Peev Xwm ruaj khov titable) ua kom haum rau cov chaw lim dej tsis zoo:

Cov Khoom Siv Tshuaj: Reactors, kev hloov pauv cua sov, thiab cov raj xa hluav taws xob uas kov cov tshuaj corrosive (piv txwv li cov kua tshuaj, thiab tshuaj pleevlog}}}}}}}}}}}}}}}}}}}}}}} ntawv nroj tsuag.

Cov ntaub ntawv tawm / marine: Subsea Wellheads, risers, thiab marine kho vajtse. Nws tiv taus dej hiav txwv corrosion deb zoo dua li stainless hlau, zam kev pitting lossis crevice corrosion hauv cov dej qab zib.

Lub Zog Loj: Turbine txuas thiab cov tub rog ua kom sov pa hauv roj, chav, thiab cov ntoo hluav taws xob nuclear, qhov uas nws ua kom muaj kev kub ntxhov thiab ua kom sov siab.

(3) Automotive (high - performance performance performance & Racing)

Thaum tsis tshua muaj nyob rau hauv cov pawg -}}}}}}}}}}}}} Cov tsheb siab dua los txhim kho kev nrawm, roj kev ua tau zoo, thiab cov khoom siv hluav taws xob, thiab durability:

Tsheb Sib Tw Tsheb: Cov Cheebtsam Tshem Tawm (Springs, Tswj Caj Npab), Tso Tshuab, thiab Tsav Shafts. Nws lub teeb yuag txo tsis muaj kev tiv thaiv tsis tau zoo, txhim kho kev tuav, thaum nws cov cua sov tiv thaiv tau tiv thaiv kev tawm siab kub siab.

Lub Tsheb Hluav Taws Xob (EV): Roj teeb cua txias tshuab thiab lub cev muaj zog. Corrosion Kuj tiv thaiv kev txwv los ntawm cov kua txias kom huv, thiab ntom ntom tsis zoo pab txhawb qhov hnyav ntawm cov roj teeb uas hnyav.

(4) kev kho mob (txwv, luv - sij hawm los yog tsis {{2} {2} {{2} {2} {2} {{2} {2} {{2} {{2} - Kev Siv Kev Siv)

Tsis zoo li Ti - 6 teev -}}}}} 12v (vanadium-dawb kev txhawj xeeb (txaus ntshai ntawm ion leaching). Yog li, nws txoj kev kho mob raug txwv:

Kev phais cov twj: Scalpels, forceps, thiab orthopedic xyaum. Nws yog ib lub tsho rau tus kws phais mob nplij, corrosion - tiv taus autoclave kom tsis muaj menyuam, thiab ruaj rau kev siv dua.

Luv -} Lub Sij Hawm Li: Cov pob txha nyob ib ntus lossis cov paib (siv rau lub lis piam mus rau lub hlis, ua ntej tshem tawm), nyob qhov twg} Term Vagadium leaching tsis muaj kev pheej hmoo.

Kho Hniav: Kev Siv Hniav thiab Scalers, raws li nws tiv taus corrosion los ntawm qaub ncaug thiab tu tshuaj thiab tu tshuaj.

(5) Cov Kev Ua Si & Kev Ua Si

Ti {- 6v yog siv nyob rau hauv cov cuab yeej kis las kis las rau nws lub zog thiab lub teeb hnyav:

Aerospace -} qib tsheb kauj vab: Thav duab thiab cov khoom sib xyaw (cranksets, handkSebars) uas sib npaug txhav, detabent, thiab lub teeb rau kev sib tw cycling.

Cov Chaw Ntaus Golf: Club Hau (tsav tsheb, iRons) thiab hauv cov duab. Nws lub zog siab tso cai rau cov phab ntsa tasner, kev faib tawm qhov hnyav hnyav rau kev txhaj tshuaj ntev dua.

Toj roob hauv pes: Khov axes, crampons, thiab nce toj bolts. Nws tiv thaiv corrosion los ntawm kev ya raws thiab dej khov, thiab nws lub zog ua kom muaj kev nyab xeeb hauv cov xwm txheej huab.

2. Dab tsi yog lub tensile lub zog ntawm Ti-6AL-4V?

Lub zog tensile ntawm TI-6AL-4V yogtsis tu ncua{{0- Nws nyob ntawm cov alloy'sKev Kho Cua Sov Lub XeevthiabTxoj kev ua(xws li, forging, kev tsim khoom ntxiv). Hauv qab no yog lub zog tensile muaj zog, piv txwv nrog cov qauv kev lag luam (piv txwv li, ASTM B265 rau kev lag luam siv, ASTM F136 rau kev kho mob- qib):

Kev Kho Cua Sov / Ua Xeev	Raug tensile lub zog	Cov ntsiab lus tseem ceeb
Ib qho tseem ceeb	860 mpa mpa - 1100 mpa	Feem ntau lub xeev, ntsuas lub zog thiab ductility (elongation: 10-15%). Siv nyob rau hauv dav dav ib tug General Aerospace, kev lag luam, thiab cov cuab yeej kho mob.
Tov {-} kho thiab laus (sta)	1170 MPA - 1400 MPA	The highest-strength state, achieved via age hardening (precipitating fine -phase particles to block dislocations). Siv rau high - Log load suav zoo li cov dav hlau tsaws iav lossis tsheb ncua tsheb ncua tsheb.
Kub {- ua haujlwm (li -} forged / extruded)	830 MPa - 1030 MPa	Nruab nrab lub zog, khaws cia tom qab sib sau kub (piv txwv li, forging) tsis muaj kev sib tw tag nrho. Feem ntau ua ntej ua ntej ntxiv kev kho cua sov rau kev siv cua sov tshwj xeeb.
Kev tsim ntxiv tsim (AM, li - ua)	900 MPA - 1150 MPA	Raws li -} ua ntu (piv txwv li, hmoov, hmoov tensab) feem ntau muaj ib nyuag qib siab sib piv rau lossis siab dua ib qho kev sib piv tau yog ib qho me me} 6v. Kev ua (piv txwv li, sta) tuaj yeem ua kom muaj zog rau 1300-1400 MPA.

Tsab ntawv: Tensile lub zog yuav sib txawv me ntsis los ntawm qib (piv txwv li cov lag luam thiab kev kho mob). Kev Kho Mob - Qib Ti-6V (ASTM F136) muaj qhov sib zog ua rau lub zog tsis sib xws rau cov qhab nia muaj cov qhab nia. Rau cov ntawv tseem ceeb, ib txwm hais txog cov qauv tshwj xeeb.

3. Dab tsi yog qhov nyuaj ntawm Ti-6AL-4V?

Hardness ntawm Ti-6V yog kev ntsuas ntawm nws txoj kev tiv thaiv kom indentation lossis khawb, thiab zoo li lub zog, nws txawv nrogKev Kho Cua Sovthiabkev tsimCov. Hardness yog feem ntau ntsuas siv peb hom nplai: Brinell (HBW), Rockwell (HRC, HV). Hauv qab no yog lub hardness tseem ceeb rau cov tseem ceeb:

Kev Kho Cua Sov Lub Xeev	Brinell Hardness (HBW, 3000 kg load)	Rockwell Hardness	Vickers Hardness (HV, 300 g load)	Cov ntawv tseem ceeb
Ib qho tseem ceeb	280 - 340 HBW	29 - 35 HRC; 95 - 100 hrb	300- 360 hv	Ntsuas hardness thiab ductility; Yooj yim rau siv lub tshuab (txheeb ze rau cov lus nyuaj).
Tov {-} kho thiab laus (sta)	350 - 400 HBW	37 - 42 HRC	370 - 430 hv	Hnyav nyuaj vim yog hnub nyoog tawv; siab dua coj tsis kam tab sis qis dua.
Kub {- ua haujlwm (li -} forged)	270 - 330 HBW	28 - 34 HRC; 94 - 99 hrb	290 - 350 HV	Me ntsis qis tawv tawv dua li annealed lub xeev; Ntau ducas tab sis tsis tshua muaj nqi - tsis kam.
Kev tsim ntxiv tsim (AM, li - ua)	300- 360 HBW	30 - 36 HRC	320 - 380 hv	Hardness yog feem ntau 5-10% siab dua annaled Ti-}} 6V-4V vim yog qhov zoo, sai sai tsim microstructure hauv yog cov txheej txheem. Post-annealing txos hardness kom phim cov analealed ntau.
