Kev Tshawb Fawb thiab Tshuab Txhua Hnub, Beijing, Cuaj Hlis 20th: Pab pawg tshawb fawb tshawb fawb coj los ntawm Australian engineers tau sau qhov tseeb ntawm "Nature Materials" uas lawv siv 3D luam ntawv thawj zaug kom tau txais cov titanium alloy nrog lub zog tshwj xeeb tshaj plaws rau hnub tim, uas yog kev lag luam aerospace. , ib tug loj leap rau pem hauv ntej rau kev tiv thaiv, lub zog, thiab biomedical industries.
Qhov kev tshawb fawb zaum kawg no los ntawm Monash University qhia tau hais tias kev siv tshuab 3D tshuab luam ntawv tuaj yeem siv los tsim cov khoom lag luam muaj zog titanium alloys nrog cov khoom siv tsis tau pom dua.
"Titanium alloys xav tau kev ua haujlwm nyuaj thiab thermo-mechanical ua kom ua tiav lub zog siab xav tau rau qee qhov kev siv tseem ceeb," cov kws tshawb fawb tau piav qhia. "Peb pom tias cov txheej txheem tsim khoom ntxiv xws li 3D luam ntawv tuaj yeem siv lawv cov txheej txheem tsim tshwj xeeb los tsim cov titanium alloys zoo hauv cov khoom lag luam muaj titanium alloys." Super muaj zog thiab thermally ruaj khov qhov chaw yog tsim nyob rau hauv lub alloy. "
Nyob rau hauv txoj kev tshawb fawb kawg, pab neeg tshawb fawb tau ua tiav lub zog tensile ntawm tshaj 1600 MPa tom qab kev kho cua sov yooj yim ntawm kev lag luam titanium alloy, lub zog tshwj xeeb tshaj plaws ntawm 3D luam ntawv hlau rau hnub tim. Cov khoom siv nrog kev ua tau zoo thiab kev siv dav hauv ntau lub teb tau ua rau txoj hauv kev.
Ntau xyoo dhau los, 3D luam ntawv thev naus laus zis tau coj mus rau lub sijhawm tshiab ntawm kev tsim hlau vim nws lub peev xwm los tsim cov khoom nrog txhua qhov geometry. Titanium alloys yog tam sim no lub ntsiab 3D luam ntawv hlau qhov chaw siv nyob rau hauv aerospace teb, tab sis feem ntau cov lag luam titanium alloys ua nrog 3D tshuab luam ntawv tsis tuaj yeem ua tiav cov khoom txaus siab, yog li lawv tsis tuaj yeem siv rau hauv qee qhov chaw lossis tsis txaus siab, tshwj xeeb tshaj yog lawv tsis muaj. lub zog ntawm chav tsev kub thiab kub.
"Cov kev tshawb fawb tshiab tshaj plaws muab txoj hauv kev tshiab rau nag lossis daus ntxiv ntawm cov khoom lag luam uas tuaj yeem siv los tsim cov khoom tiag tiag nrog cov duab nyuaj rau kev siv cov khoom siv thauj khoom, qhov twg tsis muaj titanium alloys tau siv rau hnub no," cov kws tshawb fawb tau hais. Peb tau ua qhov no los ntawm 3D luam ntawv ua ke nrog kev kho cua sov yooj yim, uas kuj txhais tau hais tias cov txheej txheem cov nqi rau cov cuab yeej siv tshiab tau qis dua piv rau lwm cov ntaub ntawv uas muaj zog zoo sib xws.
