Yog qib 5 titanium muaj zog dua li cov hlau -} kev paub

1. Cov ntsiab lus ntsiab lus: Qeb 5 Titanium vs. nquag Steels

Ua ntej, nws yog ib qho tseem ceeb kom qhia meej cov ntaub ntawv hauv nqe lus nug:

Qib 5 Titanium (Ti-6al-4V): Cov feem ntau siv titanium alloy, muaj ntawm 90% titanium, 6% aluminium, thiab 4% vanadium. Nws sib npaug muaj zog, corrosion tsis kam, thiab ua haujlwm tsis tau, thiab tau cais ua "petanium-

Hlau: Ib qeb dav ntawm cov hlau - alloys sib txawv, nrog lub zog sib txawv ntawm hom. Rau cov ntsiab lus sib piv, peb tsom mus rauhigh - lub zog steels(piv txwv li, hlau me me yog qhov tsis muaj zog heev rau kev sib piv ncaj qha;

2. Lub zog sib piv: los ntawm kev ntsuas tseem ceeb

Lub zog tsis yog ib qho khoom ntiag tug; engineers cia siab rau kev ntsuas tshwj xeeb los ntsuas kev ua tau zoo. Cov lus hauv qab no qhia qib 5 titanium nrog tus sawv cev siab- lub zog steels:

Lub Zog Metric	Qeb 5 Titanium (Ti-6al-4V, Annealed)	4140 Alloy Steel (tshav kub -}} kho: HRC 30)	304 Stainless Hlau (Anneealed)
Paib lub zog(ᵧᵧ): Kev ntxhov siab ntawm uas muaj kev cuam tshuam mus tas li (tseem ceeb rau kev nyab xeeb qauv).	~ {860 mpa mpa (125,000 psi)	~ 1,100 MPa (160,000 PSI)	~ 205 MPa (30,000 PSI)
Lub zog tensile(σₜ): Ntau tshaj kev ntxhov siab ua ntej pob txha lov.	~ 930 MPA (135,000 PSI)	~ 1,250 mpa (180,000 psi)	~ 515 mpa (75,000 PSI)
Kev nyuaj(Rockwell C): Kuj tseem ceeb rau indentation (cuam tshuam rau hnav / kev puas tsuaj).	~ 30 hrc	~ 30-35 hrc	~ 7 hrc

Tseem Ceeb Takaways Los Ntawm Lub Zog Metrics:

Tawm tsam 304 stainless hlau: Qeb 5 titanium yogsiab muaj zogCov. Nws cov txiaj ntsig ib lub zog (~ {860 MPa MPa) yog tshaj 4x siab dua 304 tus qauv siab tshaj plaws (~ 205 MPa), thiab nws lub zog tensile yog ze li ob. Nws kuj yog qhov nyuaj dua (30 hrc vs . 20 hrc), muab qhov zoo dua rau cov khawb lossis deformation.

Tawm tsam siab - lub zog alloyy steels (piv txwv li, 4140): Qeb 5 titanium yogtsis muaj zog nyob rau hauv raw zog cov ntsiab lusCov. Thaum tshav kub kub -} kho 4140 steel muaj zog tshaj thiab tensile vs {}} mpa mpa mpa mpa cia rau tensile) thiab sib piv lossis siab dua lossis tawv me ntsis.

Tawm tsam ultra- siab-} lub zog hlau (piv txwv li, g ,let 100): Qhov sib pauv dav dav ntxiv. Qhov 100, siv nyob rau hauv Aerospace thiab kev tiv thaiv, muaj lub zog tensile ntawm ~ 1,900 mpa}}} ntau dua li ob npaug ntawm qib 5 titanium.

3. Cov ntsiab lus tseem ceeb: Lub zog - rau {{2} Qhov hnyav} qhov hnyav. Piv txwv

Ceev: Qib 5 Titanium muaj qhov ntom ntom ntawm ~ 4.51 g / cm³, uas yogTsuas yog 60% ntawm cov hlau(steel ceev: ~ 7.85 g / cm³).

Kev cuam tshuam: Rau ib feem uas xav tau ib theem tshwj xeeb ntawm lub zog (piv txwv li, lub dav hlau bracket), qib 5 titanium feem yuav~ 40% ntaistshaj li ib feem sib npaug ntawm cov hlau. Txawm hais tias ib tug steel alloy (zoo li 4140) tau muaj zog dua, lub titanium Tshooj ua tiav kev ua tau zoo ib yam li ntawm qhov hnyav.

Piv txwv li: Los txhawb 10,000 n thauj khoom tsis muaj kev cuam tshuam nrog kev sib cav sib ceg ntawm 9 mm² (vim nws yog 1,100 mpa kom muaj zog). Ib qib 5 titanium pas nrig, nrog 860 mpa}}}} {} {{}

4. Lwm yam uas cuam tshuam "kev ua tau zoo" (dhau ntawm lub zog)

Hauv tiag - Cov ntaub ntawv World, "lub zog" tsis tshua muaj kev txiav txim siab nkaus xwb. Qeb 5 titanium feem ntau outperforms hlau hauv lwm qhov chaw tseem ceeb:

Corrosion Kuj: Qib 5 Titanium yog cov tshuaj tiv thaiv corrosion nyob rau hauv hars chinesp, actures oxide txheej (ti₂) uas txwv tsis pub oxidation ntxiv. Feem ntau cov xim hlau (suav nrog 4140)), piv txwv li cov hlau nplaum kom tsis txhob muaj xeb muaj xeb (piv txwv li, thaum qib 5 titanium tsis.

Qaug zog muaj zog: Kev qaug zog (kev tsis taus rau qhov tsis txaus siab, piv txwv li qhov kev cai sib tw) yog qhov tseem ceeb rau cov dav hlau tsaws iav lossis cov pa hluav taws kub. Qeb 5 titanium muaj zog nkees heev- ntau dua 2140 nyob rau hauv Cyclic Chaw thau khoom science.

Biocompatibility: Tsis zoo li cov hlau feem ntau (uas yuav muaj npib tsib (uas yuav muaj kev sib zam), qib 5 titanium yog biocompible. Nws yog dav siv hauv kev kho mob kev mob (piv txwv, kev hloov kho hniav, kev cog hniav) vim tias nws tsis ua rau cov tshuaj tiv thaiv kab mob thiab sib xyaw nrog tib neeg cov pob txha.

5. Xaus: Nws nyob ntawm daim ntawv thov

Txhawm rau teb "yog qib 5 titanium muaj zog dua li cov hlau?":

Nyob rau hauv raw qoob loo / tensile lub zog: Tsis muaj {{{- high {1}- muaj zog hlaus (piv txwv li 4140, tus lej 100) muaj zog dua.
