Gr.5｜Ti-6Al-4V titanium alloy yog dab tsi?

Mar 04, 2024

Piav

Gr.5 (Ti-6Al-4V) occupies ib qho chaw ntawm American standard titanium alloy cov ntaub ntawv, thiab nws lub npe domestic yog: TC4 titanium alloy khoom.
Titanium 6 Aluminium 4 Vanadium feem ntau suav hais tias yog "lub hauv paus" ntawm kev lag luam titanium vim nws yog cov feem ntau siv titanium alloy nyob rau lub sij hawm ntev, suav txog ntau tshaj li ib nrab ntawm tag nrho cov titanium siv. Nws yog ib qho + sib xyaw uas tuaj yeem kho cua sov kom ua tiav lub zog nruab nrab. Titanium 6 Aluminium -4 Vanadium raug pom zoo siv rau qhov kub tsis tshaj 350 degree / 660 degree F. Titanium 6 aluminium 4 vanadium muaj qhov zoo ntawm hardness zoo, lub teeb yuag, forgeability, corrosion kuj, thiab lwm yam., thiab yog dav. siv hauv kev lag luam aviation.

Nws cov khoom tsim yog qhov pib Gr.5|Ti-6Al-4V. Kev sib xyaw ua ke yog: titanium (Ti) tshuav, nitrogen (N) Tsawg dua lossis sib npaug rau 0.05, carbon (C) Tsawg dua lossis sib npaug rau 0.{{ 9}}8, hydrogen (H) Tsawg dua lossis sib npaug rau 0.015, hlau (Fe) Tsawg dua lossis sib npaug 0.40, oxygen (O) Tsawg dua lossis sib npaug rau 0.20, aluminium (Al) (5 .5-6.75), vanadium (V) 3.5-4.5

Khoom piav qhia

Raws li cov khoom siv titanium dual-qib, Gr.5 titanium alloy, (Ti-6Al-4}V) muaj cov khoom siv dav dav thiab tuaj yeem ua haujlwm ntawm 400 degree ntev nrog lub zog zoo kawg. . Vim nws cov khoom kub kub zoo heev, nws yog qhov tsim nyog rau kev tsim cov khoom siv thauj khoom xws li lub cav cav tshuab tshuab, kiv cua, cov npoo ntse thiab vaj tse radiators.

Lub cev muaj zog

1. Me me deformation coefficient:Qhov no yog ib qho tseem ceeb ntawm TC4 titanium alloy txiav kev ua, qhov deformation coefficient tsawg dua los yog ze rau 1. Cov zawv zawg kev sib txhuam deb ntawm cov chips ntawm lub ntsej muag rake yog ntau ntxiv, ua kom cov cuab yeej siv nrawm dua.
2. Siab txiav kub:Txij li cov thermal conductivity ntawm titanium alloy yog me me (tsuas yog sib npaug rau 1/5 mus rau 1/7 ntawm No. 45 steel), qhov ntev ntawm kev sib cuag ntawm cov nti thiab lub ntsej muag rake yog luv heev, thiab cov cua sov tsim tawm thaum txiav tsis yog. yooj yim khiav. , concentrated nyob rau hauv lub txiav cheeb tsam thiab ib tug me me nyob ze ntawm lub txiav ntug, thiab txiav kub yog siab heev. Nyob rau hauv tib txoj kev txiav, qhov ntsuas kub tuaj yeem ua tau ntau dua ob zaug siab li thaum txiav 45 steel.
3. Loj txiav quab yuam ib cheeb tsam:Lub ntsiab txiav quab yuam yog li 20% me dua thaum txiav hlau. Txij li qhov kev sib cuag ntev ntawm lub nti thiab lub ntsej muag rake yog luv heev, qhov txiav quab yuam ntawm ib cheeb tsam sib cuag tau nce ntau, uas tuaj yeem ua rau chipping tau yooj yim.

Gr.5|Ti-6Al-4V mechanical zog:Lub zog tensile: σb Ntau dua lossis sib npaug ntawm 895Mpa, yield zog σb Ntau dua lossis sib npaug rau 828Mpaσ: elongation: δ Ntau dua lossis sib npaug li 10%.
Gr.5|Ti-6Al-4V Corrosion kuj:Txawm hais tias titanium alloy muaj zog heev, muaj peev xwm sib npaug tsawg, thiab muaj qhov sib txawv ntawm cov thermodynamic corrosion nyob rau hauv nruab nrab, nws yog qhov ruaj khov heev hauv ntau qhov kev tshaj tawm, xws li oxidizing, nruab nrab thiab nws yog corrosion-resistant nyob rau hauv weakly txo cov xov xwm. Qhov no yog vim titanium muaj kev sib raug zoo nrog oxygen. Nyob rau hauv cov huab cua los yog oxygen-muaj xov xwm, ib tug ntom, heev nplaum thiab inert oxide zaj duab xis yog tsim nyob rau hauv titanium nto, uas tiv thaiv titanium matrix los ntawm corrosion. Txawm tias vim muaj kev siv tshuab thiab tsim kua muag, nws yuav sai sai kho nws tus kheej lossis rov tsim dua tshiab.
Titanium thiab titanium alloys suav nrog titanium 6 aluminium -4 vanadium raug cuam tshuam rau hydrogen embrittlement. Gaseous los yog tsis zoo hydrogen tuaj yeem xa mus rau hauv cov hlau, tsim cov hydrogen brittle. Yog li ntawd, thaum lub sij hawm ua cov txheej txheem, tshwj xeeb tshaj yog thaum tshav kub kub kev kho mob thiab pickling txheej txheem, cov ntsiab lus ntawm hydrogen yuav tsum tau txo kom ntau li ntau tau. Cov khoom tshwj xeeb ntawm titanium 6 aluminium -4 vanadium feem ntau qhia tias cov ntsiab lus hydrogen tsis tshaj 150ppm.
Gr.5|Ti-6Al-4V txhawb cov khoom siv vuam:ERTi-5
Nws thaj chaw siv:
Aerospace, roj drilling, khoom siv tshuaj lom neeg, khoom ua si, nkoj nkoj, thiab lwm yam
