Qeb 1 lossis 2 Titanium -} kev paub

1. Cov khoom siv tseem ceeb ua ke: tsawg heev tab sis tseem ceeb sib txawv

Qeb 1 thiab qib 2 yogCov neeg lag luam ntshiab titanium (cp ti), lub ntsiab lus lawv muaj ntau dua 99% titanium (deb siab dua li cov qib titanium qib zoo li TI-6AL-4V). Lawv thawj qhov kev sib cav sib ceg nyob hauv txoj kab txawv txawv cov qib (piv txwv li, oxygen, carbon, carbon, uas cuam tshuam ncaj qha rau lawv cov kev ua haujlwm:

Lw Elem	Qib 1 titanium	Qeb 2 Titanium	Qhov cuam tshuam ntawm kev ua kom muaj zog ntau dua (qib 2)
Pa	≤ 0.18%	≤ 0.25%	Ua kom muaj zog dua tab sis me ntsis txo cov ductility
Liv	≤ 0.20%	≤ 0.30%	Txhim kho hardness thiab tensile lub zog
Pa roj carbon	≤ 0.08%	≤ 0.08%	Tsis muaj cov ntsiab lus sib txawv ntawm qib
Nitrogen	≤ 0.03%	≤ 0.03%	Tsis muaj cov ntsiab lus sib txawv ntawm qib

Cov impurity me me drive drive cov tub ntxhais kev ua lag luam luam - tawm ntawm ob qib.

2. Cov Khoom Siv Cov Neeg Kho Mob: Lub Zog Vs. Ductility

Qhov sib txawv tshaj plaws ntawm qib 1 thiab qib 2 yog lawv li kev sib npaug ntawmlub zogthiabkev ua siab loj(muaj peev xwm ncab, khoov, lossis daim ntawv tsis muaj tawg). Qhov nyiaj tshuav no yog qhov tseem ceeb rau kev txiav txim siab rau kev sib sau, machining, lossis thauj khoom {{1} {cov khoom siv cov kabmob.

Cov cuab yeej (ASTM B265 Txuj Ci)	Qib 1 titanium	Qeb 2 Titanium	Tseem Ceeb Takaway
Lub zog tensile(Yam tsawg kawg nkaus)	240 MPa (35 ksi)	345 MPa (50 Ksi)	Qeb 2 yog ~ 44% muaj zog dua qib 1
Paib lub zog(Yam tsawg kawg nkaus)	170 MPa (25 Ksi)	275 MPa (40 Ksi)	Qeb 2 muaj ~ 62% siab dua cov txiaj ntsig lub zog (tiv taus deformation zoo dua)
Elongation(Yam tsawg kawg nkaus, hauv 50 hli)	24%	20%	Qeb 1 yog ntau ducile (ncab 20% ua ntej tawg)
Kev nyuaj(Brinell)	~ 70 HB	~ 80 hb	Qeb 2 yog qhov nyuaj me ntsis, txhim kho cov hnav tsis kam

Qeb 1: Qhov muag muag thiab ntau tshaj plaws ntawm txhua qhov kev lag luam ntshiab titanium qib. Nws lub zog qis yog offset los ntawm tshwj xeeb formability- Nws tuaj yeem ua haujlwm yooj yim {2} Khib, xaim) yam tsis tau tawg.

Qib 2: Cov feem ntau dav siv CP qib TI. Nws muab ib qho "nruab nrab hauv av" {{- siab dua lub zog dua qib 1 thaum khaws tau zoo ductility (ho tsawg dua qib 1). Nws ntxiv lub zog ua rau nws haum rau lub teeb thauj - cov kabmob cov haujlwm.

3. Corrosion Kuj: Yuav luag txhua tus (zoo tshaj plaws rau ib puag ncig ib puag ncig)

Ob qho kev nthuav dav qibNtsej Muag Corrosion Kuj, ib tug txhais lus ntawm ntshiab titanium. Qhov no yog vim kev tsim cov tuab, tus kheej - kho oxide txheej (tio₂) ntawm lawv cov nplaim dej, uas tiv thaiv:

Dej hiav txwv thiab cov tub rog ib puag ncig (tsis muaj pting lossis crevice corrosion).

Cov kua qaub me me (piv txwv li, acetic acid, citric acid) thiab alkalis.

Chloride - ric ricions (ib qho tsis muaj zog ntawm cov hlau stainless).

Tsis muaj cov tswv yim sib txawv hauv kev ua haujlwm corrosion ntawm qib 1 thiab qib 2 rau feem ntau muaj lossis cov ntaub ntawv thov. Tsuas yog nyob rau hauv hnyav heev, siab-} Cov qib tsis huv los ntawm kev tsim khoom)}

4. Fabrication & Machinability

Fabrication yooj yim me ntsis, tsav los ntawm lawv qhov ductility thiab lub zog:

Muaj meej: Qib 1 yog qhov yooj yim dua kom txias - Daim ntawv zoo li kev cog lus zoo li kev mob kho mob thiab siab elongation txo qhov kev pheej hmoo ntawm kev tawg. Qib 2 tseem tuaj yeem txias txias {6} Cures

Luam ntawv: Ob qib tau txiav txim siab "muaj qhov nyuaj" rau lub tshuab (piv rau titanium) vim tias titanium tsim nyob rau ntawm lub cuab yeej txiav) thiab kev nruj. Txawm li cas los xij, qib 1 qis dua hardness ua rau nws me ntsis yooj yim dua rau kev siv dua qib 2-txawm tias qhov sib txawv, thiab ob qho tib si yuav tsum tau cov khoom tshwj xeeb (piv txwv li, carbide ntxig) thiab txias.

Hwj txwv: Ob qib qib no muaj kev siv ntau heev siv cov txheej txheem zoo li TIG (Tungsten inert roj) vuam. Qeb 1 tus neeg tsis huv loj yuav ua rau cov qib huv huv me ntsis, tab sis qib 2 tseem dav welded hauv kev muaj cov txheej txheem kom tsim nyog.

5. Cov ntawv thov raug: txuam nrog qib kom xav tau

Qeb "qib" zoo dua yog qhov uas ua kom haum rau koj daim ntawv thov ua ntej (piv txwv li, lub zog, nqi):

Thaum Twg Xaiv Qib 1 Titanium

Xaiv rau qib 1 yogductility thiab formability yog qhov tseem ceeb, thiab lub zog siab tsis tas yuav tsum tau:

Nyias -} walled tubing (piv txwv li, rau kev ua kua tshuaj, kev kho cov roj kho).

Cov khoom siv yooj yim (piv txwv li, cov pob qij txha, cov pob qij txha nthuav dav hauv cov piping).

Medical impants xav tau cov qauv kev ua kom muaj zog (piv txwv li, qee qhov kho hniav yooj yim, cov phiaj xoo thenhopedic).

Tsawg - pa taws lossis cov hnab ntim khoom (qhov chaw ceeb toom kom txuag tau thiab corrosion tsis muaj peev xwm ntau dua li siab thauj khoom muaj peev xwm).

Thaum Twg Xaiv Qib 2 Titanium

Xaiv qib 2 rauGeneral - lub hom phiaj ntawv thov yuav tsum muaj lub zog sib npaug thiab kev sib luag(Nws yog tus nqi tshaj plaws -}} Siv tau zoo CP TI qib):

Txheej txheem txheej txheem (piv txwv li, nkhaus, fasteners hauv marine lossis aerospace kev lag luam).

Medical impans (piv txwv li, pob txha screws - nws lub zog txhawb nqa thauj khoom thauj khoom thauj khoom {}} bearing).

Cov kev hloov pauv kub thiab cov hlab ntsha siab (tiv taus corrosion thiab kev kub siab ib nrab).

Cov khoom siv cov neeg siv khoom (piv txwv li, siab-} Tsom cov rooj plaub, caij tsheb kauj vab}}} pittic lub teeb thiab ruaj khov).

Tshuaj lom neeg tso tsheb tso tsheb hlau luam thiab cov kav dej (cov nyom me me corrosive kua thaum nrog kev cuam tshuam me me).
