Cov yam ntxwv ua haujlwm thiab kev siv tshwj xeeb ntawm titanium alloy

Nrog rau txoj kev loj hlob ntawm high-tech industries xws li aerospace, lub zog thiab tsheb, qhov kev thov rau cov ntaub ntawv ua tau zoo yog ua ntau thiab ntau dua. Ntawm lawv, beta titanium alloy tau dhau los ua cov khoom tseem ceeb uas tau siv dav vim nws cov khoom siv zoo heev thiab kev ua haujlwm kub. Tsab ntawv xov xwm no yuav qhia meej txog cov yam ntxwv ntawm kev ua, cov txheej txheem thiab kev siv tshwj xeeb ntawm titanium alloys.

Beta titanium alloy yog cov hlau uas muaj titanium thiab beta ruaj khov (V, Cr, Fe, Mn, Co, Ni, thiab lwm yam) nrog lub zog siab, siab tawv thiab kub stability. Ntawm lawv, theem cheeb tsam hais txog thaj av uas theem (bcc qauv) ntawm titanium ruaj khov nyob rau hauv qhov kub thiab muaj pes tsawg leeg ntawm titanium alloy. Cov khoom ntawm titanium alloy yog me ntsis qis dua cov ntawm + titanium alloy, tab sis lawv muaj oxidation zoo dua thiab kub tsis kam nyob rau hauv qhov kub thiab txias. Cov khoom tseem ceeb ntawm titanium alloy yog raws li nram no: V, Cr, Fe, Mn, Co, Ni, thiab lwm yam.

⑴ Txiav kev ua haujlwm

Beta titanium alloy muaj siab hardness thiab toughness thiab nyuaj rau txiav. Piv nrog rau lwm yam ntaub ntawv, nws yuav tsum tau ib tug loj txiav lub kaum sab xis thiab qeeb pub thiab txiav ceev kom tiav txiav. Thaum ua cov titanium alloys, xaiv cov cuab yeej thiab abrasives thiab kev txhim kho cov txheej txheem lubrication feem ntau yog siv los txhim kho nws cov kev ua tau zoo.

⑵ Thermal processing zog

Lub a / transformation point kub ntawm titanium alloy yog qis dua thiab siab dua li ntawm + titanium alloy. Qhov ntsuas kub ntawm qhov ntsuas kub yog 880 degree -900 degree . Ntawm qhov kub thiab txias, beta titanium alloys muaj qhov sib txawv loj ntawm qhov sib txawv ntawm qhov sib txawv thiab kev ntxhov siab, yog qhov ua rau cov yas deformation thiab thermal tawg, thiab yuav tsum tau ua kom txias ceev kom tswj cov khoom siv zoo heev. Thaum lub sijhawm ua haujlwm kub, cov tshuaj tiv thaiv austenitization yuav tsum raug zam, thiab cov txheej txheem pneumatic tuaj yeem siv los tswj kev deformation thiab txo lub sijhawm cua sov ntawm cov khoom.

⑶ Molding kev ua tau zoo

Beta titanium alloy muaj qhov zoo formability thiab tuaj yeem tsim siv ntau txoj kev tsim, suav nrog forging, extrusion, dov thiab kos duab. Nws tensile thiab thermoplastic zog yog sib xws nrog ntau ntau lawm.

⑴Aerospace teb

Beta titanium alloy, raws li cov khoom siv hlau nrog lub zog siab thiab kub siab, tau siv dav hauv kev lag luam aerospace. Piv txwv li, nws tuaj yeem siv los tsim cov khoom siv dav hlau, cov khoom siv thiab cov khoom siv hauv qhov chaw kub kub xws li missiles thiab satellites.

⑵ Kev kho mob

Vim tias titanium alloys muaj biocompatibility siab thiab corrosion kuj, lawv tuaj yeem siv los tsim cov khoom cog, xws li kev sib koom ua ke, kev cog hniav, thiab cov ntaub ntawv kho pob txha.

⑶ Lub zog teb

Beta titanium alloy tuaj yeem tiv taus qhov kub thiab txias, tsis yooj yim oxidized, thiab muaj cov khoom zoo heev hauv qhov kub thiab txias. Yog li, nws tuaj yeem siv los tsim cov roj laum me ntsis, cov khoom siv hluav taws xob nuclear, cov khoom siv hluav taws xob tshem tawm, thiab cov khoom siv hluav taws xob nuclear.

Raws li cov khoom siv alloy nrog ntau yam khoom, beta titanium alloy muaj ntau yam kev siv. Txawm li cas los xij, vim nws qhov siab hardness thiab toughness, nws cov kev ua tau zoo yog qhov tsis zoo thiab yuav tsum tau txiav tshwj xeeb rau kev ua haujlwm. Hauv kev siv cov tswv yim, kev xaiv cov cuab yeej siv tshuab thiab cov khoom siv kuj yuav tsum tau txiav txim siab raws li cov kev thov tshwj xeeb. Nrog rau txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, nws ntseeg tau tias titanium alloys yuav muaj kev thov dav dua yav tom ntej.
