Ti62222S Titanium Alloy Bar

Ti62222S titanium alloy, sib haum rau qib TC21, yog tsim los ntawm Ti-6242S titanium alloy, nrog rau cov nominal muaj pes tsawg leeg ntawm Ti-6Al-2Sn-2Zr-2Cr-2Mo-0.15Si. Nws yog ib hom tshiab ntawm ob-theem, siab zog, tawv, thiab kev puas tsuaj-tiv taus titanium alloy. Ti62222S titanium alloy muaj cov khoom zoo ntawm lub zog siab, siab yas, thiab siab tawv, thiab yog siv dav hauv kev lag luam aerospace. Vim muaj cov ntsiab lus siab ntawm -stabilizing cov ntsiab lus nyob rau hauv cov hlau, nws chav tsev kub tensile zog thiab tawg toughness yog ntau dua li cov zoo tib yam TC4 alloys. Cov hlau muaj xws li Al, Sn, Zr, Cr, Mo, thiab Si. Qhov sib ntxiv ntawm Mo tsuas yog ua kom lub zog tensile ntawm cov hlau ntawm chav tsev thiab qhov kub thiab txias thiab txhim kho nws cov thermal stability; Zr muab cov kev daws teeb meem ntxiv dag zog, thiab tsim nyog nce Zr cov ntsiab lus tuaj yeem kho cov qauv forged ntawm cov hlau; Kev sib xyaw ua ke ntawm Al, Sn, thiab Zr muab cov khoom siv nrog lub sijhawm ntev thiab kev nkag siab ntawm qhov kub thiab txias; Qhov sib ntxiv ntawm Si ua rau cov dispersion ntawm silicides, uas pab txhim kho cov alloy lub siab kub creep zog.
 

1. Lub cev muaj zog
Lub sijhawm hloov pauv kub ntawm Ti62222S titanium alloy tuav yog 960 ± 5 degree, thiab qhov ceev yog kwv yees li 4.48 g / cm³.

2. Cov txheej txheem ua haujlwm kub
Ti62222S titanium alloy yuav tsum tau qhib nyob rau hauv cheeb tsam thiab tiav forging 20-30℃saum toj no theem hloov point, kom ntseeg tau ib tug deformation tus nqi ntawm 30% -50% thaum lub sij hawm kawg forging (ie, forging). Qhov no ua rau lub pob tawb-weave microstructure, nrog rau ntau qhov sib cuam tshuam lamellar theem uas pab ua kom muaj lub zog zoo- sib npaug toughness thiab txhim khu lub alloy qhov creep kuj. Nyob ze - forging yuav tsum tswj lub forging cua sov rau 10℃saum toj no theem hloov point thaum nruj me ntsis tswj lub tuav lub sij hawm nyob rau hauv lub cheeb tsam kom tsis txhob overcoarsening ntawm nplej. Cov txheej txheem no pab txhim kho qhov ntev - mus rau - qhov dav qhov sib piv ntawm lamellar theem hauv lub pob tawb-weave qauv, txwv tsis pub nag lossis daus ntawm theem ntawm cov ciam teb, thiab txhim kho cov khoom siv lub zog thiab tawg toughness. Txawm li cas los xij, vim yog qhov yuav tsum tau ua rau kub thiab forging txheej txheem tswj, qhov no tsuas yog siv rau isothermal tuag forging.

3. Mechanical Properties
Chav tsev kub tensile txhua yam khoom ntawm Ti62222S titanium alloy tuav tau qhia hauv Table 1.

Ti-62222S titanium alloy muaj zoo toughness txuam, zoo heev hardenability, thiab superb superplastic forming zog. Qhov sib npaug ntawm molybdenum yog kwv yees li 5, nrog rau theem siab ntawm theem nyob rau hauv lub xeev sib npaug, muab kev kho cua sov kom muaj zog ntxiv rau cov teebmeem thiab ua rau lub sijhawm ntev - kev pabcuam ntawm 400℃. Ti-62222S titanium alloy yog tsim rau kev tsim ntau yam qauv forgings thiab weldable load-bearing Cheebtsam, nrog dav daim ntawv thov kev cia siab nyob rau hauv lub aerospace thiab civil industries. Nws cov khoom tseem ceeb semi-tiav muaj xws li daim hlau, tuav, thiab forgings. Yog li ntawd, cov alloy no tau xaiv los ntawm US Air Force rau F-22 fighter dav hlau cov ntaub ntawv. Nws tau tshaj tawm tias titanium alloys suav txog 41% ntawm cov ntaub ntawv siv hauv F-22 qib siab fighter dav hlau, nrog Ti-62222S alloy sawv cev 14%.
 

Ti-62222S titanium alloy tuav yog tsuas yog xa nrog machined los yog polished nto. Cov tsos yog xim sib xws tsis muaj qhov tsis xws luag xws li tawg, folds, lossis khawb, thiab qhov ntev ntev raws li tus qauv yuav tsum tau ua.
