| Ti-6.5Al-1Mo-1V-2Zr BT20 titanium phaj rau huab cua |
BT20 titanium alloy yog qhov ze alpha alloy tsim los ntawm tus qub Soviet Aeronautical Khoom Tshawb Nrhiav Kev Tshawb Fawb xyoo 1964, thiab nws cov ntawv sau npe yog Ti-6.5Al-1Mo-1V-2Zr.
Raws li qhov ze α hom kub kub titanium alloy, qhov sib npaug ntawm aluminium yog nce los ntawm kev ntxiv ntau yam kev qhia tshwj xeeb txhawm rau txhim kho kev ua haujlwm kub. Piv nrog rau cov tsoos α + β hom titanium alloy, qhov ze α hom kub kub titanium alloy tseem muaj zoo nkag, qaug zog tsis kam, oxidation tsis kam thiab thermal stability thaum kub. Vim nws lub zog loj thiab lub teeb yuag, nws tuaj yeem siv hauv aero-cav qhov chaw los hloov qee qhov nickel-based superalloys nrog qis zog tshwj xeeb, uas tuaj yeem txhim kho qhov sib piv-rau-qhov hnyav ntawm lub cav. Vim tias nws cov txheej txheem zoo plasticity ze rau α + β titanium alloy thiab tib cov vuam kev ua tau zoo raws li α hom titanium alloy, nws tuaj yeem siv los ua cov cav thiab lwm cov dav hlau uas ua haujlwm ntawm 300-500 ° C.
BT20 titanium alloy yog cov hom phiaj dav dav, uas yog siv los ua cov paib tuab thiab nyias daim nyias nyias, thiab tseem tuaj yeem siv los ua cov ntawv tsis nco qab, tuag hloov mus ua lwm yam, tuav thiab cov ntsiab lus.
