Yuav Ua Li Cas Tshem Tawm Batch Variation Risks hauv Titanium Alloy Mass Production
Jul 06, 2026| Qhov kev pheej hmoo loj tshaj plaws hauv kev tsim khoom loj ntawmtitanium alloy qhov chawfeem ntau tsis yog cov cuab yeej muaj peev xwm, tab sis qhov "tsis pom qhov sib txawv" ntawm cov khoom sib txawv ntawm cov khoom siv raw. Nyob rau hauv kev ua ntawm TC4 (Ti-6Al-4V), yog hais tias lub upstream billets tsis nruj me ntsis tswj rau lub transformation kub los yog ob lub tshuab nqus tsev melting txheej txheem, nws yog heev yuav ua rau txawv txav morphology ntawm theem nyob rau hauv lub microstructure. Peb tau ntsib aerospace structural component manufacturing Hoobkas nyob rau sab hnub tuaj Tuam Tshoj. Thaum lawv ua tiav qee yam ntawm lub cav mounting puag, qhov dispersion℃ntawm hardness test tau rau peb sib law liag ntawm cov khoom tiav lawm siab li HRC 3.5. Tom qab kev soj ntsuam rov qab, qhov teeb meem nyob rau hauv ob pawg ntawm titanium billets vim tsis txaus forging piv, ua rau coarse Vickers qauv nyob rau hauv nruab nrab ib feem, uas ua rau saum npoo hardened txheej qhov tob ntawm no batch ntawm qhov tob tob tshaj li ib txwm batches los ntawm ze li ntawm 40 μm, ncaj qha ua rau lub cuab tam chipping thiab loj deviation. Qhov kev pheej hmoo zoo no tshwm sim los ntawm qhov zoo ntawm metallurgical yuav tsum zam los ntawm kev taug qab tus lej ntawm lub cub tawg ntawm qhov chaw thiab ua qhov kev tshuaj ntsuam metallographic.
Qhov loj drift yog lwm tus tua neeg loj hauv kev tsim khoom loj ntawmtitanium alloy nyias-walled qhov chaw. Nws cov ntsiab lus yog qhov tsis yog -ib qho kev tso tawm ntawm cov kev ntxhov siab nyob hauv cov khoom. Ib tus neeg muag khoom ntawm UAV fuselage thav duab ib zaug ntsib qhov teeb meem raug: Cov cuab yeej kev paub rau 7075 aluminium alloy tau ncaj qha mus rau titanium alloy thav duab, thiab tom qab qhov kawg machining, qhov flatness ntawm qhov tseem ceeb ntawm qhov chaw rebounded los ntawm 0.15mm nyob rau hauv tsawg tshaj li ob teev. Qhov laj thawj yog vim li cas cov cua sov sab hauv- dov titanium alloy billets muaj cov quenching residual stress, uas tsis tuaj yeem sib npaug los ntawm kev ua haujlwm ib leeg. Thaum kawg, los ntawm kev xav kom lawv hloov lub semi- tiav cov ntawv ua tiav uas tau dhau los ntawm 600℃× 2h lub tshuab nqus tsev nqus kev ntxhov siab annealing thiab ntxiv cov txheej txheem qis qis qis tom qab kev siv tshuab ntxhib, cov khoom siv tshwj xeeb no tau daws tag nrho. Qhov no ua pov thawj tias qhov tseeb geometric ruaj khov pib nrog siab - cov ntaub ntawv zoo nrog lub xeev kev ntxhov siab.
Qhov tawm ntawm - ntawm - tswj qhov chaw roughness thiab tiam ntawm microcracks nthuav tawm qhov rhiab heev ntawm titanium alloys rau "sov defects". Vim tias muaj tshuaj lom neeg ua haujlwm siab ntawm titanium, yog tias txheej txheej txheej ntawm cov khoom siv hauv paus muaj cov pa oxygen tsis sib xws -nplua nuj txheej (feem ntau hu ua "cov pa phem txheej") lossis microsegregation, nws muaj peev xwm tsim cov nti nti thaum lub sij hawm siab - txiav ceev, ua rau muaj kev hloov pauv ntawm Ra tus nqi. Ntau qhov tseeb, cov microdefects no feem ntau yog qhov chaw yug me nyuam rau kev qaug zog tawg. Ib lub tuam txhab kho mob cog ib zaug tau tshaj tawm tias TC4 intervertebral fusion ntaus ntawv ua tiav los ntawm lawv tau pom cov kab nrib pleb zoo raws li cov cim txiav tom qab ntxuav cov kua qaub thaum kuaj fluorescent penetrant. Kev tshawb nrhiav ntxiv tau pom tias qhov nyiaj tau los ntawm cov khoom siv ntawm cov pas nrig tsis txaus, khaws qee qhov chaw microcracks los ntawm cov txheej txheem forging. Qhov no ceeb toom peb tias batch ntau lawm tsis tsuas yog yuav tsum tau muaj nyob rau hauv cov ntaub ntawv ceev tab sis kuj yuav tsum tau muaj kev cia siab ntawm lub nto zoo, thiab yuav tsum tau muab cov ntaub ntawv soj ntsuam ultrasonic raws li AMS2631 qauv.
ntsib cov teeb meem kev lag luam uas niaj hnub no,Tuam Tshoj Super Tech Co., Ltdtso siab rau nws cov khoom sib sib zog nqus engineering tsub kom muab kev txhawb zog rau cov neeg siv khoom thoob ntiaj teb. Peb feem ntau cuam tshuam nrog titanium thiab titanium alloys (Gr1-Gr5/TC4/TA series), hluavtaws pob zeb diamond, niobium-titanium thiab high-temperature alloys, thiab muaj cov khoom muag tsis tu ncua npog ntau yam ntaub ntawv xws li billets, phaj, thiab forgings. Peb nruj me ntsis ua raws li ASTM / AMS / DIN / GB cov qauv kom ntseeg tau tias txhua yam khoom xa tuaj nrog cov ntaub ntawv ntxaws ntxaws (MTC) thiab cov ntaub ntawv txheeb xyuas metallographic, ntsuas qhov sib xws ntawm hardness thiab cov qauv los ntawm qhov chaw. Txawm hais tias nws yog qhov ceev ceev ntawm cov khoom lag luam lossis cov kev pabcuam melting thiab kev kho cua sov rau cov xwm txheej huab cua,Tuam Tshoj Super Techtuaj yeem muab cov khoom muag txaus thiab kev tswj xyuas kev ua haujlwm zoo los pab koj ua tiav hauv kev tsim khoom loj ntawm titanium alloys.
