1. Qhov teeb meem tam sim no hais txog lub zog hlau hauv 3D luam ntawv
Hlau hmoov tau melted txheej los ntawm txheej thiab tawv kom tsim cov duab uas tsim nyog thaum lub tshuab luam ntawv 3D. Txawm li cas los xij, qhov ntsuas kub hnyiab, txias txias, thiab txheej los ntawm txheej txheem kev hloov kho ntawm cov khoom siv ntawm cov kev sib txawv los ntawm cov kev ua tiav los yog kev zam kev paub. Cov duab qoob loo, theem faib tawm, thiab microscopic flaws-uas cuam tshuam 3D luam tawm cov hlau ua haujlwm thiab lub zog-cuam tshuam cov kev hloov pauv no tshwj xeeb tshaj yog.
Lub zog thiab ductility ntawm cov ntaub ntawv hlau tau ntev tau ua lag luam; Siab zog feem ntau tshwm sim los ntawm kev du me me, thiab rov ua dua. Tab sis nyob rau hauv lub realm ntawm 3D luam ntawv, qhov kev lag luam no tau loj hlob zuj zus ntau dua. Thaum lub sijhawm 3DS muaj feem ntau tsim nyog tsim los ntawm kev ua cov txheej txheem ntawm cov khoom siv hlau thiab cov khoom siv sib txawv thiab cov nplej ua kom muaj kev cuam tshuam rau kev ua luam ntawv.
2.techniques kom nce 3D luam tawm hlau zog
Cov kws tshawb nrhiav tau ua tiav ntau txoj hauv kev los tsa lub zog ntawm 3D luam tawm cov hlau.
Txhim kho Alloy Tsim: Microstructure thiab Hlau cov yam ntxwv tuaj yeem hloov tau ntau los ntawm kev sib txawv ntawm cov alloy muaj pes tsawg leeg. Rau titanium alloys, piv txwv li, siv Molybdenum (MO), tuaj yeem pab nce theem kev ruaj khov thiab kev sib dhos ntawm lub zog thiab ductility. Los ntawm kev siv ntawm DUAL ua hauj lwm alloy tsim, 3D luam tawm titanium alloy nrog cov kev ua haujlwm siab tshaj plaws ntawm Denmark, Chongqing University, thiab University of Queensland. Nws ductility yog 26%; Nws cov txiaj ntsig lub zog yog 926MPA.
Txoj kev tswj: txheej txheem Micro cov kev sib tw tau txo qis thaum lub zog ua kom qis dua qub, thiab cov hlau lub zog thiab tsim nyog txhim kho cov yam ntxwv.
Kev hloov kho cov nplej 'microstructure thiab hardness ntawm cov hlau yuav tsa los ntawm kev txhim kho cov duab qoob loo thiab daim ntawv. Siv cov kev siv ultrasonic siab, kho cov chaw, lossis yog li ua kom muaj zog, yuav pab tau muaj zog thiab ua kom muaj zog ntxiv thiab ua rau muaj 3D luam tawm cov hlau.
Tom qab kev ua tiav: tom qab luam ntawv, kev kho cua sov tuaj yeem pab sib luag yog cov ntsuas 'microstructure thiab zoo kom ua tau zoo dua. Txawm li cas los xij, nws yuav tsum tau hais tias kev ua tib zoo xaiv ntawm kev kho cua sov yog qhov tseem ceeb txij li kev kho mob tshav kub yuav nqa lub micros microstructure tshiab.
3.Cov kev sib tw uas yog cov ntaub hlau tseem ceeb
Lub zog siab thiab ductility ntawm titanium alloys tau ua rau cov neeg tsis nyiam ua ntej, thiab cov neeg ua haujlwm siab tau hais tawm los ntawm pawg neeg thoob teb chaws suav nrog suav nrog Queensland. Sib nrug los ntawm nws cov neeg kho tshuab zoo zoo, no titanium alloy muaj ua haujlwm zoo ua kom muaj peev xwm ua tau zoo, uas qhib lub qhov rooj rau siv nyob rau hauv upscale cov haujlwm suav nrog aerospace.
Kev Koom Tes Pab Koom Tes ntawm Lub Tsev Kawm Cov Hlau ntawm Suav Tsev Kawm Ntawv Kev Tshawb Fawb thiab University of California, Berkeley, yog Ti {2}} v alloy los ntawm kev tsim Ib txoj kev tshiab npham ntawm kev tsis xws luag thiab cov nqaij-ntawm-theem kev cai lij choj, nrog kev qaug zog tsis kam. Ntawm tag nrho cov ntaubntawv povthawj siv cov ntaub ntawv nkees nkees, no Qhov kev ua tau zoo no qhia tau cov txiaj ntsig tshwj xeeb ntawm 3D luam tawm kev tsim tawm thiab hloov tib neeg kev paub ntawm kev ua haujlwm qis ntawm 3D luam cov ntaub ntawv.
Ib pab neeg hauv tsev kawm ntawv qib siab tau tsim cov siab loj dua aluminium almoy haum rau 3D luam ntawv. Los ntawm kev hloov pauv hloov pauv ntawm kev cobalvalt, hlau, npib tsib xee, cov txheej txheem ua ke los tsim lub zog yooj yim thiab muaj peev xwm ua kom zoo dua qub. Qhov no aluminium alloy lub zog surpasses 900mpa, yog li tsim cov cib fim zoo rau kev siv lub siab-zog aluminium alloys hauv ntau lub sectors.
