Lub npe pom ntau tshaj plaws rau lub titanium alloy TI-6AL-4V yogQeb 5 Titanium(nquag shortened rau "TI qib 5" hauv kev lag luam cov ntsiab lus). Qhov kev tsim no tsis yog lam tau {2} Nws yog cov qauv ntawm titanium, thiab ams 4v) los cais cov txheej txheem no raws li nws muaj pes tsawg leeg.
Ti -} 6al {- 4V Khwv tau nws cov xwm txheej uas yog qhov feem ntau ntau yam thiab siv tau titanium alloy thoob ntiaj teb. Nws muaj pes tsawg leeg - 6% aluminium (uas ua kom muaj zog ntxiv, uas muaj zog tsis txaus ntseeg) thiab ua kom muaj kev phom sij rau kev lag luam xws li kev lag luam xws li aerospace (piv txwv li, Lub dav hlau cav sib xyaw, airframe qauv), xws li, orthopedic kev cog lus, cov khoom siv hniav), thiab cov khoom siv ua haujlwm siab (corrosion-resistant Cheebtsam). Tsis zoo li cov qib ntshiab titanium (piv txwv li, alter 2) lossis lwm yam alloys yog kev nkag siab zoo rau kev tsim qauv rau kev tsim tshwj xeeb rau 6al-4V muaj pes tsawg leeg.
Cov txiaj ntsig lub zog ntawm Ti -} 6v tsis yog tus nqi ruaj khov-nws txawv raws li cov alloy'sXeev kev ua lub xeev(Qhov uas txiav txim siab nws microstructure) thiab, mus rau tsawg dua, nws daim ntawv (piv txwv li, ntawv, bar, Forging). Tos lub zog yog qhov tseem ceeb hauv kev tsim khoom lag luam vim tias nws sawv cev rau cov khoom siv uas pib deformation), ntau dua li tsuas yog tsuas yog deformation). Hauv qab no yog cov xa tawm zog tshaj plaws rau cov hauj lwm tshaj plaws ntawm Ti-6al-4V, ua raws li cov qauv kev lag luam (piv txwv li):
Annealed Ti-6AL-4V:
Annealing koom nrog cua sov rau ib qho kub rau qhov kub thiab txias hauv qab nws betus (feem ntau 700-800-8002-1472 Qib F) ua raws li kev ua kom qeeb. Cov txheej txheem no muag muag cov khoom, txhim kho kev ua kom zoo nkauj "alpha {}}}}} ntawm alpha thiab beta titanium theem).
Raug zoo muab lub zog:860 MPa rau 930 MPa(sib npaug rau 124,700 psi rau 134,900 psi).
Piv txwv cov Qauv Cov Qauv: ASTM B265 yuav tsum muaj tsawg kawg lub zog muaj zog ntawm860 MPa rau Annaled Ti-6al-4V Sheet / phaj.
Tov -} Kho thiab laus (sta) ti-6al-4V:
Tus txheej txheem STA muaj ob kauj ruam: (1) "daws kev kho mob" {} txias} (2) "Laus" {- rheathw rau qhov kub qis (480-596-110 Qhov no tsim kom muaj zog dua, nyuaj metructure.
Raug zoo muab lub zog:1,030 MPa rau 1,100 MPa(sib npaug rau 149,400 psi rau 159,500 psi).
Piv txwv li Cov Qauv Cov Qauv: Ams 4928 (Aerospace -}}}}}}}}}}}}}}}}} mpa cia (150,000 psi).
Kub - ua haujlwm ti-6al-4V:
Kub ua hauj lwm (piv txwv li, kev zam, dov ntawm qhov kub tshaj 600 degree, lossis 1112℃f) deflems lub alloy thaum nws yog ducy, ua kom nws cov qauv zeb. Paib lub zog ntawm no ntog ntawm anealed thiab sta xeev.
Raug zoo muab lub zog:900 MPa rau 980 MPA(sib npaug rau 130,500 psi rau 142,100 psi).
Nws yog ib qho tseem ceeb kom nco ntsoov tias kev hloov pauv me me tuaj yeem tshwm sim ntawm cov tuam ntxhab, thiab cov qauv ntsuas kub (piv txwv li, ntsuas qhov ntsuas ntsuas (piv txwv li, ntsuas qhov chaw ntsuas (piv txwv li, ntsuas qhov ntsuas (piv txwv li, ntsuas kub tensile) geometry rau ib as8).
Tensile lub zog (tseem hu ua qhov kawg tensile muaj zog, UTS) yog qhov kev ntxhov siab tshaj plaws uas cov khoom siv tuaj yeem tiv taus ua ntej kev nro. Zoo li paib lub zog, ti-6al-4V lub tensile lub zog yog hnyav nyob ntawm nwsXeev kev ua lub xeev(Microstructure) thiab daim ntawv. Hauv qab no yog lub zog tensile muaj zog rau cov xeev tseem ceeb, haum nrog cov qauv kev lag luam thoob ntiaj teb:
Annealed Ti-6AL-4V:
Annealed State's Alpha - beta microstructure ua ntej cov hlau (piv txwv li alloys, carbon hlau).
Raug zog tensile:930 MPa rau 1,000 MPA(sib npaug rau 134,900 psi rau 145,000 psi).
Cov Qauv Yuav Tsum: ASTM B266 Qhia Txog Qhov Tsawg Yam Lub Zog Tsawg ntawm 930 MPa rau Annaled Ti-6al-4V Sheet / phaj.
Tov -} Kho thiab laus (sta) ti-6al-4V:
Tus txheej txheem STA tau ua rau cov khoom siv alpha me tam sim no, ua rau muaj cov ntaub ntawv loj tshaj plaws ntawm cov ntawv thov thauj khoom zoo li Aerospace Fasteners lossis kev cog hniav.
Raug zog tensile:1,100 MPa rau 1,170 MPA(sib npaug rau 159,500 psi mus rau 169,700 psi).
Cov qauv yuav tsum tau: Ams 4928 yuav tsum muaj lub zog tsawg kawg ntawm 1,103 MPa (160,000 PSI) rau Sta Ti-6al-4V.
Kub - ua haujlwm ti-6al-4V:
Kub ua hauj lwm kho cov qoob loo loj thiab thooj microstration theem, ua rau lub zog tensile, uas muaj zog tshaj annealed cov khoom tab sis qis dua Sta.
Raug zog tensile:980 MPa rau 1,050 MPa(sib npaug rau 142,100 psi rau 152,300 psi).
