Khoom Taw Qhia
Ti62222S titanium alloy sib raug rau hauv qib TC21 thiab yog tsim los ntawm Ti-6242S titanium alloy. Nws cov nominal muaj pes tsawg leeg yog Ti-6Al-2Sn-2Zr-2Cr-2Mo-0.15Si. Nws yog ib hom tshiab ntawm dual-theem siab-lub zog, tawv, kev puas tsuaj-tolerant titanium alloy. Ti62222S titanium alloy muaj cov khoom zoo xws li lub zog siab, siab plasticity, thiab siab toughness, thiab yog dav siv nyob rau hauv aerospace teb. Nws tuaj yeem siv rau hauv cov qauv dav hlau tis sib koom ua ke, lub tsev nres tsheb, lub fuselage thiab tsaws iav kev sib txuas thav duab, lub cav raug tshem tawm cov pob qij txha, thiab lwm yam, nrog rau cov khoom tseem ceeb lossis tseem ceeb ntawm cov kabmob uas yuav tsum tau muaj zog thiab kav ntev.
Khoom Parameters
Chav tsev kub tawg toughness thiab qaug zog tawg kev loj hlob kev ua tau zoo ntawm Ti62222S titanium alloy tuav tau pom nyob rau hauv Table 1, thiab lub siab - kub tensile zog muaj nyob rau hauv Table 2.

Khoom nta thiab kev siv
Ti62222S titanium alloy muaj cov txiaj ntsig zoo xws li lub zog siab, siab tawv, thiab tsis tshua muaj qhov tawg, ua rau nws siv dav hauv aerospace thiab lwm yam haujlwm. Los ntawm kev kho cov txheej txheem kho cua sov, Ti-62222S titanium alloy tuaj yeem ua tiav lub pob tawb-weave microstructure uas muaj lub zog zoo dua, plasticity, toughness, thiab tawg propagation kuj piv rau lwm cov microstructures. Nyob rau hauv tej yam kev mob tsis inferior rau Gr.5 titanium alloy, nws puas toughness, tawg kev loj hlob tsis kam, thiab thermal stability yog tswj, thaum lub zog yog ib tug txiav txim ntawm magnitude siab tshaj li ntawm Gr.5 titanium alloy. Titanium alloys feem ntau yog siv rau lub fuselage tom qab ntawm lub dav hlau tshiab, tis sib koom ua ke nrog rau qhov kub thiab txias, cav thav duab, thiab lwm yam tseem ceeb los yog cov khoom tseem ceeb, nrog rau qhov tseem ceeb ntawm cov khoom thauj khoom uas yuav tsum tau muaj zog thiab kav ntev.
Khoom Paub meej
Ti62222S titanium alloy tuav yog tsuas yog xa nrog machined los yog polished nto. Cov tsos yog xim tsis sib xws, tsis muaj kab nrib pleb, folds, khawb, lossis lwm yam tsis xws luag, thiab qhov ntev ntev raws li tus qauv yuav tsum tau ua.
