Raws li kev ua haujlwm siab, titanium alloy tau siv nyob rau hauv ntau cov teb, siv tshuaj lom neeg vim nws cov khoom siv kho mob thiab cov khoom siv kho mob corrosion. Ntawm ntau cov titanium alloys, ti -3 al {2}}. 5V titanium alloy tau ua qhov kev tshawb fawb kub thiab kev ua tau zoo heev.
I. Cov kev sib xyaw ntawm Ti -3 al -2. 5v titanium alloy
Lub ntsiab tshuaj lom neeg ntawm ti -3 al -2. 5V titanium alloy yog titanium (al) thiab vanadium (v). Ntawm cov no, titanium yog lub hauv paus keeb nrog cov ntsiab lus ntawm ntau tshaj 90%, muab cov alloy nrog lub zog siab, qis dua thiab corrosion zoo heev. Aluminium, nrog cov ntsiab lus ntawm 3%, ua raws li kev txhawb nqa theem uas tsim kho cov alloy lub zog thiab kub - kub tsis kam. Thiab vanadium, ntawm 2.5%, ua raws li cov beta stabilizing keeb, pab txhim kho kom txhim kho alloy cov plasticity thiab kev nruj.
Thib ob, tus ntawm cov ntsiab lus ntawm kev ua yeeb yam ntawm cov alloy
1. Lub luag haujlwm ntawm Aluminium keeb
Aluminium ua si lub luag haujlwm tseem ceeb hauv Ti-Al -2. 5v titanium alloy. Nws tsis tsuas yog tso cov qauv alpha-theem ntawm alloy thiab txhim kho lub zog kub thiab oxidation tiv taus ntawm cov khoom siv tes tau thiab muaj zog ntawm lub alloy. Txawm li cas los xij, siab dhau cov ntsiab lus zoo heev yuav txo cov tawv ntawm cov alloy thiab nce txoj kev pheej hmoo ntawm brittleness. Yog li ntawd, tus nqi ntawm txhuas nyob rau hauv ib qho kev xav tau kom muaj kev tswj hwm kom tswj tau qhov sib npaug ntawm lub zog thiab tawv.
2. Lub luag haujlwm ntawm lub cim vanadium
Vanadium, raws li -Stabilizing keeb, plays ib lub luag hauj lwm loj hauv ti {}} al {2}}. 5v titanium alloys kom txhim kho kev muaj zog thiab tawv. Nws nthuav dav-phahe ncua, tso cai rau cov alloy los tswj hwm kev ua kom zoo thiab lub tshuab hluav taws xob ntau dua. Vanadium kuj tseem txhim kho cov corrosion tsis kam ntawm cov alloy, tshwj xeeb tshaj yog ua tau zoo hauv chloride ib puag ncig. Txawm li cas los xij, ntau cov ntsiab lus vatadium ntau dhau tuaj yeem ua rau coarse nplej nyob rau hauv alloy ntawm cov khoom kub, cuam tshuam cov neeg kho lub zog thiab nkees muaj zog.
III. Theem qauv thiab cov yam ntxwv ntawm alloys
Theem teeb tsa ntawm Ti-Al -2. 5V titanium alloy feem ntau muaj-all} {5}} theem. -Pease muaj hexagonal kaw-kab (HCP), uas qhia txog lub zog thiab cov qauv zoo, uas muaj kev sib zog siab thiab lub zog loj. Los ntawm kho cov ntsiab lus ntawm txhuas thiab vanadium raws li cov txheej txheem kho cua sov, cov piv ntawm-tshuaj yuav raug tswj kom zoo rau cov kev ua tau zoo ntawm cov alloy.
IV. Thov kev cia siab ntawm Ti -3 al-.5v titanium alloy
Nrog nws lub zog zoo, kev ua kom nruj thiab corrosion tsis kam, ti {}} al {1}}. 5v {1}}. Nyob rau hauv lub teb chaws aerospace, nws tau dhau los ua ib qho ntawm cov qauv kev tsim qauv tseem ceeb siv hauv kev tsim cov dav hlau fuselage, cav qhov chaw thiab lwm qhov tseem ceeb. Hauv kev lag luam tshuaj, nws corrosion resistance ua nws zoo tagnrho rau corrosion-resistant khoom thiab cov piping. Tsis tas li ntawd, nyob rau hauv cov chaw kho mob, ti {{{}} al -2. 5V titaning}. 5V titely}.
V. Qhov Kawg thiab Outlook
Hauv cov ntsiab lus, ti -3 al -2 Nyob rau yav tom ntej, nrog kev nce qib ntawm science thiab thev naus laus zis thiab kev txhim kho kev siv thev naus laus zis, daim ntawv thov} ib qho kev pab cuam. 5v titanium alloy yuav txuas ntxiv mus ntxiv. Nyob rau tib lub sijhawm, hauv kev nthuav dav ntawm kev ua kom zoo ntawm cov txheej txheem alloy yuav txuas ntxiv ua kom tau raws li cov ntawv thov engineering ntxiv. Yog li ntawd, cov kev tshawb nrhiav thiab kev txhim kho ntawm Ti -3 al {}. 5V titanium alloy yuav muab kev txhawb zog zoo thiab kev tsim kho tshiab ntawm kev lag luam ntsig.
