Yog li ntawd, Ti-3Al-8V-6Cr yog dav siv nyob rau hauv marine engineering, tshuaj kev lag luam, kev kho mob thiab lwm yam kev lag luam.
5.Ti-4Al-2.5Sn
Ti-4Al-2.5Sn yog titanium alloy nrog lub zog nruab nrab thiab zoo corrosion kuj. Nws lub zog thiab toughness yog me ntsis qis dua Ti-6Al-4V, tab sis nws cov weldability zoo dua thiab tuaj yeem ua tiav siv cov txheej txheem vuam tsoos. Yog li ntawd, Ti-4Al-2.5Sn yog dav siv nyob rau hauv marine engineering, tshuaj lom neeg kev lag luam, kev kho mob thiab lwm yam kev lag luam.
Dab tsi yog cov txheej txheem forging ntawm titanium alloy daim hlau? Titanium alloy forging yog cov txheej txheem ntau heev. Ntau lub tuam txhab muaj kev thov siab heev rau phaj forgings hauv kev ua haujlwm forging. Titanium alloy phaj forging muaj zoo corrosion kuj thiab stability. Cov txheej txheem forging ntawm titanium alloy daim hlau yog qhov tsim nyog rau kev tsim cov forgings zoo. Cia peb saib ntawm titanium alloy phaj forging txheej txheem.
Cua sov: Muab titanium alloy phaj rau hauv qhov cub kom cua sov kom ncav cuag qhov kub ntawm forging. Kev saib xyuas yuav tsum tau ua kom tsis txhob oxidation thiab hlawv thaum lub sij hawm cua sov.
Forging: Forging ntawm lub tshuab forging los tsim cov duab thiab qhov loj me. Cov kauj ruam no yuav tsum tau rov ua ntau zaus raws li qhov tsim nyog.
Kev kho cua sov: Txhim kho cov khoom siv ntawm titanium alloys los ntawm kev kho cua sov, nrog rau lub zog tensile, yield zog thiab elongation.
Txias: Lub forged titanium alloy phaj yog txias kom stabilize nws cov duab thiab loj.
Kev kho deg: Raws li xav tau, titanium alloy phaj forgings yog polished, coated los yog pickled los txhim kho lawv corrosion kuj thiab zoo nkauj.
Thaum lub sij hawm qis-kub forging, qhov kev hloov pauv ntawm cov forgings tsawg heev. Thaum forged hauv qab 700 degree, muaj tsawg oxide scale tsim thiab tsis muaj decarburization ntawm qhov chaw. Yog li ntawd, tsuav yog lub zog deformation nyob rau hauv qhov kev tsim ntau yam, txias forging tuaj yeem ua tiav qhov tseeb qhov tseeb thiab qhov chaw tiav. Tsuav qhov kub thiab lubrication thiab txias yog tswj tau zoo, sov forging hauv qab 700 degree kuj tuaj yeem ua tiav qhov tseeb. Thaum lub sij hawm kub forging, txij li lub zog deformation thiab deformation kuj yog me me, loj forgings nrog cov duab nyuaj tuaj yeem forged. Txhawm rau kom tau txais forgings nrog qhov tseeb qhov tseeb, kub forging tuaj yeem siv rau hauv qhov kub ntawm 900-1000 degree . Tsis tas li ntawd, kev saib xyuas yuav tsum tau them rau kev txhim kho qhov chaw ua haujlwm ntawm kub forging. Lub neej ntawm forging tuag (kub forging yog 2-5 txhiab, sov forging yog 10,000-20,000, txias forging yog 2-50,000) yog luv dua forging nyob rau hauv lwm qhov kub thiab txias. Yog, tab sis nws muaj kev ywj pheej zoo thiab tus nqi qis.
Muaj ntau ntau titanium alloy forging txheej txheem. Txhua kauj ruam yuav tsum muaj kev tswj xyuas nruj thiab kev ua kom zoo ntxiv ntawm kev ua haujlwm ntawm forgings. Xaiv tus kws tshaj lij forging ua cov chaw tsim khoom tuaj yeem txhim kho qhov zoo ntawm cov khoom.
