Pab pawg kws tshawb fawb Australian tau ua thawj 3D luam ntawv ntawm lub zog tshwj xeeb tshaj plawstitanium alloy puas tau, ib tug loj leap nyob rau hauv aerospace, tiv thaiv, zog, thiab biomedical industries.
Cov kev tshawb fawb tshiab los ntawm Monash University qhia tau hais tias kev txiav-ntug 3D luam ntawv thev naus laus zis tuaj yeem siv los tsim cov khoom lag luam ultra-high-strength titanium alloys nrog cov khoom siv tsis tau pom dua.
"Titanium alloys xav tau sophisticated casting thiab thermal machining kom ua tiav lub zog siab xav tau rau qee yam kev siv tseem ceeb. Cov khoom siv ntxiv tsim xws li 3D luam ntawv tuaj yeem siv lawv cov txheej txheem tsim tshwj xeeb los tsim cov khoom muaj zog, thermally ruaj khov hauv kev lag luam titanium alloys."
Nyob rau hauv txoj kev tshawb no tshiab, pab neeg no ua tiav tensile lub zog ntawm ntau tshaj 1600 MPa tom qab kev kho cua sov yooj yim ntawm ib tug coj mus muag titanium alloy, lub siab tshaj plaws lub zog ntawm tag nrho cov 3-D luam ntawv hlau rau hnub tim, paving txoj kev rau zus tau tej cov structural cov ntaub ntawv nrog cov cim microstructure thiab cov khoom zoo heev uas tuaj yeem siv dav hauv ntau qhov chaw.
Cov kev tshawb fawb tshiab tshaj plaws muab txoj hauv kev tshiab rau nag lossis daus hardening ntawm kev lag luam alloys, uas tuaj yeem siv los tsim cov khoom tiag tiag nrog cov duab nyuaj thiab tuaj yeem siv rau hauv thaj chaw ntawm cov kabmob. Titanium alloys tsis tau siv nyob rau hauv daim teb no txog tam sim no. Tsis tas li ntawd, qhov no yog ua tiav los ntawm 3D luam ntawv ua ke nrog kev kho cua sov yooj yim, uas tseem txhais tau hais tias cov txheej txheem cov nqi ntawm cov cuab yeej tshiab tshaj plaws yog qis dua li lwm cov ntaub ntawv uas muaj zog zoo sib xws.
