Qhov txawv thiab kev sib raug zoo ntawm GR5 Titanium thiab GR23 Titanium
Jan 15, 2026
Gr5 titanium alloy yog ib qho - titanium alloy ntse tsim los ntawm Tebchaws Meskas hauv xyoo 1954. Nws muaj 6% -stabilizing cov ntsiab lus thiab 4% -stabilizing element V. Cov nominal muaj pes tsawg leeg ntawm Gr5 titanium alloy yog 7.0 txhuas sib npaug, 2.9 molybdenum, thiab molybdenum. 10%-15% beta theem hauv lub xeev annealed. Al txhim kho chav sov lub zog thiab thermal zog ntawm cov hlau alloy los ntawm cov khoom siv tshuaj ntxiv dag zog rau theem hauv Ti-Al-V system, thiab V yog ib qho ntawm ob peb cov ntsiab lus alloy hauv titanium alloys uas tuaj yeem ua kom muaj zog thiab txhim kho plasticity. Cov txiaj ntsig zoo ntawm V ntawm cov yas ntawm titanium alloys yog tias nws tsis nce qhov sib piv ntawm -state lattice c/a axis zoo li feem ntau cov ntsiab lus alloy, tab sis txo qhov sib piv, yog li txhim kho qhov tsim ntawm theem thiab zam kev siv mus ntev. Alloy embrittlement tshwm sim thaum tus txheej txheem.
Cov yam ntxwv tseem ceeb ntawm Gr5 titanium alloy yog cov khoom zoo heev thiab kev ua haujlwm zoo. Gr5 titanium alloy muaj qhov nruab nrab qhov kub thiab txias lub zog, kev nkag siab zoo thiab thermal stability, siab qaug zog tsis kam thiab tawg tawm tsis kam nyob rau hauv dej hiav txwv, nrog rau kev puas siab puas ntsws toughness thiab tsis kam rau thermal ntsev kev nyuaj siab corrosion. Nws tseem tsis tshua muaj siab rau hydrogen dua li TC2 thiab TC1 alloys, thiab tsim nyog rau kev tsim khoom ntau yam ua haujlwm nyob rau hauv ntau qhov kub thiab txias ntawm -196 ~ 450 degree, tshwj xeeb tshaj yog cov khoom tsim los siv cov kev txwv kev puas tsuaj. Gr5 titanium alloy kuj muaj cov txheej txheem zoo plasticity thiab superplasticity, thiab tsim nyog rau kev tsim siv ntau txoj kev ua haujlwm siab, thiab rau vuam thiab machining ntau txoj hauv kev.
Lub ntsiab ib nrab- cov khoom tiav ntawm Gr5 titanium alloy yog cov tuav, square discs, discs, nyias daim hlau, daim hlau tuab, profiles thiab cov xov hlau, thiab lwm yam, uas yog siv rau hauv castings (ZGr5).
Gr5ELI yog ib qho kev txhim kho ntawm Gr5. Nws qhov sib txawv tseem ceeb yog qhov sib txawv Al cov ntsiab lus thiab cov ntsiab lus qis ntawm cov ntsiab lus Fe, N, H, thiab O.
Gr5ELI titanium alloy tau dhau los ua kev kho mob phais kev cog hniav vim nws cov biocompatibility zoo, tsis tshua muaj elastic modulus, tsis tshua muaj ntom, zoo tiv thaiv-corrosion zog, tsis yog - toxicity, siab yield zog, ntev qaug zog lub neej, loj yas nyob rau hauv chav tsev kub, thiab yooj yim tsim. cov khoom zoo tagnrho rau tej yam. Kev kho mob Gr5ELI titanium alloy daim hlau feem ntau yog siv rau kev kho pob txha taub hau, pob txha grafting, thiab lwm yam, uas muaj cov kev xav tau siab dua ntawm lub zog, qaug zog lub neej, plasticity, thiab lwm yam.
Titanium alloy yog ib qho alloy uas muaj titanium raws li lub hauv paus thiab lwm yam ntxiv. Titanium muaj ob lub isomorphous crystals: titanium yog ib qho isomer nrog lub melting point ntawm 1668 degree. Nws muaj qhov ze - ntim hexagonal lattice qauv hauv qab 882 degree, uas yog hu ua -titanium; nws yog lub cev -centered cubic qauv saum toj 882℃. Cov qauv fret hu ua beta-titanium. Los ntawm kev siv cov yam ntxwv sib txawv ntawm cov saum toj no ob lub qauv ntawm titanium, ntxiv cov ntsiab lus alloying tsim nyog kom maj mam hloov cov theem hloov pauv kub thiab cov ntsiab lus, titanium alloys nrog cov qauv sib txawv tau txais.
Gr5 ELI titanium alloy yog raws li Gr5 alloy thiab txo cov ntsiab lus ntawm interstitial ntsiab C, O, N thiab impurity Fe. Lub zog yog txo, tab sis lub toughness tuaj yeem txhim kho tau zoo. Gr5 ELI muaj plasticity zoo, toughness, zoo vuam kev ua tau zoo thiab qis -kub kev ua tau zoo, thiab yog dav siv nyob rau hauv tseem ceeb teb xws li cryogenic engineering, kho mob, nkoj thiab aircraft.
Gr5 alloy tuaj yeem siv rau hauv qhov chaw zoo tib yam lossis kub kub, thiab Gr5ELI alloy tuaj yeem siv rau hauv ultra- qhov kub thiab txias.
Gr5 titanium alloy thiab Gr5ELI titanium alloy muaj cov qib zoo sib xws: T-6A-4V / Qib 5 (American qib), BT6 (Russian qib), IMI318 (British qib), TiAI6V4 (German qib).
Kev tsim khoom siv kho mob: Rau cov pob txha thiab pob qij txha raug mob los ntawm kev raug mob thiab qog nqaij hlav hauv tib neeg lub cev, titanium thiab titanium alloys yog siv los tsim cov pob qij txha, pob txha daim hlau thiab cov ntsia hlau, uas tam sim no tau siv dav hauv kev kho mob. Kuj tseem siv tau rau hauv cov pob qij txha (xws li lub taub hau femoral), pob qij txha hauv caug, pob qij txha, pob qij txha, metacarpophalangeal pob qij txha, cov pob qij txha interphalangeal, mandibles, dag vertebrae (spinal orthoses), pacemaker shells, artificial hearts (lub plawv-{zoo li tus li qub), artificial dental orthoses) thiab titanium mesh hauv pob txha taub hau yas phais, thiab lwm yam.
Titanium thiab titanium alloys tau txais kev saib xyuas ntxiv vim lawv lub zog tshwj xeeb, biocompatibility, thiab zoo corrosion kuj rau lub cev kua.
Ti 6Al-4V ELI yog qib ntawm Ti 6Al-4V nrog cov qauv me me, uas tuaj yeem ua tiav qhov siab tshaj plaws thiab tsim nyog rau cov dej hiav txwv thiab qhov kub thiab txias. Qib no ntawm alloy feem ntau yog siv nyob rau hauv lub annealed mob. Ti 6Al-4V yog cov khoom xaiv zoo dua hauv kev kho mob cog.
Cov txheej txheem ntau lawm yog: nruab nrab so annealing ntawm 900-120 degrees Fahrenheit rau 1-4 teev thiab cua txias. Muab ob npaug rau annealing, puag ncig tuav thiab forgings yog tov annealed ntawm ib tug beta hloov kub ntawm 50-100 degrees Fahrenheit, tuav rau tsawg kawg yog 1 teev, ces cua txias, ces reheated ntawm 1300-1400 degrees Fahrenheit, tuav rau tsawg kawg yog 1 teev, thiab ces cua txias. Relaxation annealing yog tsim nyog tom qab vuam.
