Aluminium titanium alloy, Al-Ti

Titanium alloy yog nyiaj-dawb hlau, uas muaj ntau yam khoom zoo heev. Ntawm 4.54g / cm3, titanium yog 43% lub zog dua li hlau thiab hnyav dua me ntsis tshaj li hlau nplaum, lub npe nrov ntawm lub teeb hlau. Cov neeg kho tshuab zog yog ib yam li hlau, ob zaug muaj zog npaum li txhuas thiab tsib zaug muaj zog dua li cov hlau nplaum. Titanium yog qhov kub kub resistant, melting taw tes 1942K, siab dua kub ze li ntawm 1000K, siab dua li cov hlau yuav luag 500K.

Cov khoom ntawm titanium thiab txhuas:
Titanium alloy yog nyiaj-dawb hlau, uas muaj ntau yam khoom zoo heev. Ntawm 4.54g / cm3, titanium yog 43% dua li hnyav dua hlau thiab hnyav dua me ntsis tshaj li hlau nplaum, lub npe nrov ntawm lub teeb hlau. Cov neeg kho tshuab zog yog ib yam li hlau, ob zaug muaj zog npaum li txhuas thiab tsib zaug muaj zog dua li cov hlau nplaum. Titanium yog qhov kub kub resistant, melting taw tes 1942K, siab dua kub ze li ntawm 1000K, siab dua li cov hlau yuav luag 500K.
Yog li ntawd, nws tau nyiam cov xim dav dav thiab dhau los ua qhov tseem ceeb ntawm kev tshawb fawb ntawm cov ntsej muag sib xyaw ua ke.
Lub alloy yooj yim muaj cov khoom siv zoo hauv lub cev thiab tshuab thiab muaj qhov pom tseeb zoo dua li cov titanium alloys thiab superalloys zoo tib yam. Cov khoom ntawm Ti-Al intermetallic tebchaw yog siab dua Ti alloys hauv txhua qhov, uas yog qhov tseem ceeb rau cov khoom siv aeronautical. Vim tias qhov cuam tshuam ntawm covalent daim ntawv cog lus, diffusion-hais txog qhov kub-txias khoom, xws li nkag, lub zog ruaj khov thiab pob txha tawv, tuaj yeem hloov kho. Nyob rau tib lub sijhawm, nws muaj qhov ua tau zoo kub-siab oxidation tsis kam thiab corrosion tsis kam, yog li nws yog qhov kub cov yam ntxwv cov khoom nrog lub peev xwm zoo.
Kev siv cov titanium thiab txhuas:
Titanium alloy kuj tseem siv nyob rau hauv kev lag luam nqus txheej. Nws tuaj yeem ua rau kom pom tseeb ntawm cov hom phiaj ntawm cov khoom tawg yooj yim raws li cov khoom siv raw rau magnetron sputtering txheej. Hauv cov txheej txheem los ua cov tshuab nqus cov phiaj rau cov khoom siv, titanium aluminium alloy muaj ntau yam ntawm cov khoom sib txuam, feem ntau yog siv cov khoom siv titanium aluminium atom ratio (ntawm%): 90:10, 80: 20,70: 30, 50:50, 30:70 , 20:80, 10:90. Titanium aluminium alloy tuaj yeem tsim los ntawm nqus nqus thaum cov ntsiab lus ntawm titanium atom ntau dua los yog sib npaug li 50%. Thaum cov ntsiab lus ntawm titanium poob qis thiab cov ntsiab lus ntawm aluminium nce, nws tsuas yog tsim los ntawm hmoov metallurgy kom tau raws li qhov xav tau ntawm cov khoom siv cov hom phiaj. Thaum cov titanium atoms ntau dua los yog sib npaug li 80%, titanium alloy kuj tuaj yeem tsim thiab dov.
