Qib 2 Titanium: Daim Ntawv Ua Lag Luam Dawb

Qib 2 titanium muaj ntau dua 99% ntshiab titanium, nrog cov kab me me ntawm impurities xws li oxygen, hlau, thiab carbon. Nws yooj yim metallurgy txhais tau hais tias nws tsis muaj lub siab xav alloying cov ntsiab lus, ua rau cov khoom muag muag, cov khoom siv.

Qhov tsis muaj cov ntsiab lus alloying txhais tau tias Qib 2 tswj qhov siab tshaj plaws corrosion kuj, vim impurities tsawg thiab tsis muaj cov theem ntxiv tau qhia rau cov hlau matrix. Cov qauv ntshiab no yog lub luag haujlwm tsim kom muaj kev ruaj khov thiab tus kheej - kho oxide zaj duab xis rau ntawm nws qhov chaw, tiv thaiv lub fastener los ntawm kev tawm tsam tshuaj lom neeg hnyav.

Txawm hais tias nws yog ductile thiab corrosion-resistant, Qib 2 muaj zog nruab nrab piv rau qib alloyed.

Qib 5 Titanium: Alloyed rau lub zog

Qib 5 titanium suav nrog kwv yees li 6% txhuas thiab 4% vanadium, hloov cov titanium ntshiab rau hauv ib qho muaj zog alpha-beta alloy. Qhov no complex microstructure, tus cwj pwm los ntawm alpha thiab beta theem, ua rau kom txhua yam muaj zog thiab qaug zog tsis kam.

- Aluminium ua raws li alpha-theem stabilizer, pab txhawb lub zog siab thiab nkag siab.

- Vanadium stabilizes theem beta, ntxiv toughness thiab txhim kho kev qaug zog.

Cov ntsiab lus ntxiv alloying txo cov thermal conductivity li ntawm 60% piv rau Qib 2, uas yog qhov kom zoo dua nyob rau hauv siab -kub aerospace qhov chaw raws li nws tiv thaiv cov cua kub ntau dhau.

Qhov no alloying, txawm li cas los xij, me ntsis cuam tshuam txog kev tiv thaiv corrosion piv rau ultra-titanium ntshiab, ua rau nws muaj kev cuam tshuam ntau dua rau cov cheeb tsam corrosion hauv cheeb tsam hnyav.

Lub zog thiab Tensile Performance

Qib 5 titanium fasteners outshine Qib 2 hauv kev tawm los thiab tensile lub zog - ib qho tseem ceeb hauv kev siv cov qauv. Thaum Qib 2 muaj lub zog tawm los ntawm ib puag ncig 275 MPa thiab lub zog tensile kawg nyob ze 350 MPa, Qib 5 yog li ntawm kwv yees li 880 MPa mus rau ntau dua 1100 MPa rau kev tawm los thiab tshaj 1000 MPa hauv lub zog tensile.

Qhov no peb - mus rau plaub npaug ntawm kev muaj zog ua rau kev siv cov khoom me me, sib zog ua kom muaj peev xwm tiv taus cov neeg kho tshuab thiab cov kev ntxhov siab uas muaj nyob hauv aerospace, tsheb, thiab kev siv tub rog.

Hardness thiab hnav tsis kam

Qib 5 fasteners tso saib ua kom muaj zog ntxiv, ua rau muaj kev tiv thaiv zoo dua rau kev hnav, khaus, thiab deformation los ntawm kev vibration lossis cyclic loading. Cov yam ntxwv no tseem ceeb heev nyob rau hauv siab -load pob qij txha raug rau repetitive torqueing los yog torque fluctuations thaum lub sij hawm ua hauj lwm thiab txij nkawm cycles.

Qib 2 qhov qis hardness tuaj nrog cov txiaj ntsig hauv machinability thiab ductility tab sis txwv nws siv qhov chaw hnav thiab qaug zog tiv thaiv yog qhov kev txhawj xeeb loj.

Ductility thiab Elongation

Qib 2 titanium fasteners yog ductile ntau dua, tso cai rau elongation ntawm 20% thiab 30%, uas ua rau lawv yooj yim rau khoov, daim ntawv, los yog weld thaum lub sij hawm tsim los yog installation.

Qib 5 fasteners, thaum muaj zog, muaj qhov txwv elongation li ntawm 10% mus rau 15%, txhais tau tias lawv xav tau kev tswj xyuas ntau dua kom tsis txhob tawg hauv kev tsim cov txheej txheem tab sis excel ib zaug ntsia hauv siab - lub luag haujlwm muaj zog.

Qib 2: Qhov Kev Sib Tw Corrosion

Lub purity ntawm Qib 2 titanium equis nws nrog tshwj xeeb tsis kam rau oxidizing ib puag ncig, chlorides, acids, thiab ntsev, ua rau nws zoo tagnrho rau marine, tshuaj ua, thiab biomedical daim ntaub ntawv.

Nws cov txheej txheem spontaneously, ruaj khov oxide txheej tiv thaiv qhov chaw los ntawm corrosion, thiab yog hais tias mechanically khawb, zaj duab xis no hloov kho sai sai -ib qho cuab yeej hu ua *self-passivation.*

Qib 2 tshwj xeeb tshaj yog tiv taus kev ntxhov siab -vim ua rau xeb tawg, muaj kev txhawj xeeb ntau zaus hauv chloride- thaj chaw nplua nuj, txhawb nqa nws qhov tsim nyog hauv marine fasteners, desalination nroj tsuag, thiab tshuaj nroj tsuag.

Qib 5: Zoo heev tab sis tsis kam me ntsis

Qib 5 titanium fasteners tuav zoo heev corrosion kuj nyob rau hauv feem ntau tab sis yuav ua tau me ntsis resilient dua qib 2 nyob rau hauv tej qhov chaw vim cov alloying ntsiab. Cov theem txhuas thiab vanadium tuaj yeem txhawb galvanic corrosion hauv chloride - nplua nuj lossis acidic ntau yog tias tsis muaj kev tiv thaiv zoo.

Txawm li cas los xij, qhov sib txawv no tsis tshua muaj qhov tsis tsim nyog rau Qib 5 rau kev siv aerospace lossis tsheb siv, qhov twg muaj kev tiv thaiv corrosion yog qhov dav tab sis tswj hwm los ntawm cov txheej txheej thiab kev tswj hwm ib puag ncig.

Qib 5 titanium nthuav tawm txo cov thermal conductivity, kwv yees li 60% tsawg dua Qib 2. Qhov kev hloov hluav taws xob qeeb qeeb no yog qhov zoo hauv kev siv aerospace lossis cav qhov twg thermal rwb thaiv tsev pab tswj lub zog ntawm qhov kub siab.

Ob qib ua tau zoo nyob rau hauv qhov kub thiab txias, tab sis Qib 5 txhawb kev txhim khu kev qha kev ntseeg siab mus txog ib ncig ntawm 400 degree, tshaj Qib 2 qhov raug 316℃kev txwv.

Hluav taws xob, ob qib muaj cov conductivity tsis zoo piv rau cov hlau xws li tooj liab lossis txhuas, tab sis Qib 2 zoo li muaj hluav taws xob ntau dua me ntsis, uas tuaj yeem cuam tshuam cov ntawv thov uas yuav tsum tau siv hluav taws xob hauv av lossis tiv thaiv kev txiav txim siab.

Fabrication thiab Formability

Qib 2 qhov softness thiab ductility ua rau nws yooj yim rau welding, tsim, thiab khoov, haum rau cov ntawv thov uas cov khoom yuav tsum haum rau shaping lossis ntawm - qhov chaw hloov kho.

Qib 5 qhov ua kom tawv tawv thiab txo cov ductility txhais tau hais tias yuav tsum siv cov cuab yeej tshwj xeeb, kev siv lub tshuab ua kom txias, thiab tswj kev txiav nrawm kom tsis txhob tawg lossis cov cuab yeej hnav. Nws qhov xwm txheej nyuaj, txawm li cas los xij, txhais tau tias tsawg dua kev pheej hmoo ntawm deformation nyob rau hauv load ib zaug ntsia.

Tus nqi cuam tshuam

Qib 5's complex alloy chemistry thiab cov txheej txheem ua haujlwm ntxiv, suav nrog kev kho cua sov thiab kev tswj xyuas zoo, thawb nws tus nqi siab dua piv rau Qib 2. Rau cov ntawv thov xav tau lub zog loj thiab kav ntev, tus nqi them nqi no yog qhov ncaj ncees.

Qib 2 qhov yooj yim metallurgy thiab machinability yooj yim coj cov nqi txuag uas ua rau nws muaj zog tus neeg sib tw rau corrosion-tseem ceeb tab sis qis dua cov ntawv thov kev ntxhov siab, pab txhim kho qhov project pob nyiaj siv.

Qib 2: Corrosion thiab Ductility Focused Siv

Vim nws cov corrosion kuj zoo dua thiab yooj yim fabrication, Qib 2 titanium fasteners yog nyiam nyob rau hauv:

- Marine ib puag ncig, suav nrog kev tsim nkoj, cov chaw tawm ntug dej hiav txwv, thiab chav desalination.
