Titanium Alloy Metamaterial
Cov kws tshawb fawb tau tsim cov titanium alloy metamaterials uas yuav siv tau rau hauv aerospace thiab kev tsim hluav taws xob tshiab. "Qhov metamaterial no qhia tau hais tias zoo heev cov qauv kev ua tau zoo thiab ntau yam kev ua haujlwm, thiab tuaj yeem txhawb kev tuaj txog ntawm lub sijhawm tshiab ntawm lub teeb yuag, siab zog, thiab ntau yam khoom siv hlau metamaterials." Ma Qianhe, tus kws tshaj lij ntawm RMIT University hauv Australia, tau tawm tswv yim txog cov txiaj ntsig tshiab thiab nws Pab Pawg thiab cov kws tshaj lij tshuaj xyuas tau hais tias:
Thaum lub sij hawm kev tshawb fawb, Ma Qian pab neeg tsim thiab npaj ib lub teeb yuag, siab-lub zog mechanical metamaterial (tsawg ceev, siab yield zog) nrog ib tug Ti-6Al-4V multi-topology qauv. Cov khoom no tau txais txiaj ntsig zoo thaum tshav kub kub ua haujlwm, zoo heev corrosion kuj thiab biocompatibility ntawm Ti-6Al-4V alloy, thiab yuav tsum tau siv rau hauv ntau qhov chaw.
Piv txwv li:
Ua ntej, nws tuaj yeem siv los ua cov qauv sandwich rau high-speed aircraft thermal tiv thaiv tshuab. Thaum ua los ntawm high-temperature titanium alloys, nws muaj peev xwm txawm yuav siv tau ntawm kub nce mus txog 600 degree. Yog hais tias tus qauv yog ua los ntawm high-temperature npib tsib xee-raws li alloy, nws kuj yuav tsum tau siv nyob rau hauv lub kub kub (piv txwv li, ze rau 900 degree).
Thib ob, nrog nws qhov tshwj xeeb kev ua tau zoo zoo xws li lub teeb yuag, siab zog, corrosion kuj, thiab kub tsis kam, nws kuj tuaj yeem siv los tsim cov titanium drones, uas tuaj yeem siv rau kev soj ntsuam ze, tua hluav taws thiab hluav taws kub, los yog npaj titanium hauv aircraft. Rudder wing structural qhov chaw.
Thib peb, nws tseem tuaj yeem siv los ua cov pob txha cog cov khoom siv los npaj ntau yam khoom siv hauv tsev laus lossis cov cuab yeej pabcuam, nrog rau kev tsim cov khoom siv sib txawv.
Plaub, los ntawm kev txhim kho cov qauv ntxiv, nws xav tias yuav txo qis nws qhov ceev kom txog li 1. resistant, thiab kub-resistant titanium alloys. txoj kev.
