Ib qho kev tawg tsis ntev los no tau tshaj tawm los ntawm tus kws tshaj lij thiab nws pab neeg ntawm Royal Melbourne Institute of Technology hauv Australia. Lawv tau tsim thiab tsim ib qho tshiab Ti-6Al-4V alloy metamaterial nrog ntau cov qauv topological. Cov khoom siv hnyav thiab lub zog siab no ua rau pom qhov tshwj xeeb kub ua haujlwm, tiv thaiv corrosion, thiab biocompatibility, tau txais los ntawm Ti-6Al-4V alloy. Nws yog qhov tsim nyog rau ntau daim ntawv thov sib txawv vim tias cov khoom zoo li no.
Piv txwv li:
Nws tuaj yeem siv rau hauv cov txheej txheem sandwich rau kev tiv thaiv thermal hauv cov dav hlau ceev, txawm tias qhov kub thiab txias ze li 600 degree thaum siv cov khoom kub kub titanium alloys. Yog hais tias tus qauv yog tsim los ntawm high-temperature npib tsib xee-raws li alloys, tej zaum yuav muaj peev xwm mus ua hauj lwm nyob rau hauv txawm ntau dua kub, nce mus txog 900 degree.
Nrog nws cov kev sib xyaw tshwj xeeb ntawm lub teeb yuag, lub zog siab, kev tiv thaiv corrosion, thiab kub tsis kam, nws tuaj yeem siv rau hauv kev tsim cov titanium unmanned drones rau kev soj ntsuam ze, hav zoov thiab kev tua hluav taws, thiab raws li cov khoom siv hauv cov dav hlau tswj qhov chaw.
Nws kuj tseem tuaj yeem ua cov khoom cog rau cov pob txha hloov, ntau yam khoom siv kho mob, thiab kev tsim cov khoom sib xyaw ua ke.
Kev ua kom zoo ntxiv ntawm cov qauv tsom kom txo nws qhov ceev mus rau kwv yees li 1.
Nyob rau hauv txoj kev tshawb no, pab neeg ingeniously ua ke hollow nyias-walled pas nrig mechanical metamaterials nrog nyias phaj mechanical metamaterials, uas ua rau ib tug txawv structural daim ntawv uas diverges los ntawm yav tas los qhia metamaterial topologies. Los ntawm kev siv qhov zoo ntawm ob qho tib si cov qauv, cov khoom ua tiav qhov kev txhim kho tseem ceeb hauv kev ua haujlwm zoo thaum khaws cov yam ntxwv tseem ceeb ntawm tus thawj hollow nyias-walled pas nrig metamaterial.
