Cov kws tshawb nrhiav tau siv lub suab ua haujlwm los txhawm rau txhawm rau hlau cov hlau ua zoo rau hauv kev tsim nruj thaum lub sijhawm 3D luam ntawv.
Ib txoj kev tshawb fawb tsuas yog luam tawm hauvKev Sib Txuas Lus Xwmqhia cov suab nthwv suab nrov muaj peev xwm muaj kev cuam tshuam tseem ceeb nyob rau sab hauv micro-qauv ntawm 3D luam tawm alloys, ua rau lawv ntau sib xws thiab muaj zog dua li cov ntawv luam tawm yooj yim.
Tus thawj coj sau thiab PhD neeg sib tw los ntawm RMIT University' s Lub Tsev Kawm Ntawv ntawm Engineering, Carmelo Todaro, hais tias cov lus cog tseg tuaj yeem txhawb nqa cov qauv tshiab ntawm kev tsim cov khoom ntxiv.
& quot; Yog tias koj saib ntawm lub qauv me me ntawm 3D cov ntawv luam tawm alloys, lawv' feem ntau ua los ntawm cov muaju loj thiab ntev ntev," Todaro tau piav qhia.
& quot; Qhov no tuaj yeem ua rau lawv tsis muaj peev xwm lees paub rau kev siv engineering vim lawv qis dua kev siv tshuab thiab nce siab yuav tawg thaum luam ntawv."
& quot; Tab sis lub tshuab tsom me me ntawm cov hlau alloys peb thov ultrasound rau thaum lub sijhawm luam ntawv ntsia pom qhov sib txawv: cov nplai alloy tau zoo heev thiab tag nrho equiaxed, lub ntsiab lus lawv tau tsim kom muaj sib npaug hauv txhua qhov kev qhia thoob plaws tag nrho cov ntawv luam hlau."
Kev ntsuas pom cov feem no tau 12% txhim kho hauv lub zog tensile thiab cov txiaj ntsig kev ntxhov siab piv nrog cov tau los ntawm cov khoom siv ntxiv.
Pab neeg no tau qhia txog lawv qhov teeb meem ultrasound siv ob txoj kev lag luam qib loj: ib qho titanium alloy feem ntau siv rau qhov chaw dav hlau thiab kev cog qoob loo biomechanical, hu ua Ti-6Al-4V, thiab nickel-based superalloy feem ntau siv hauv kev ua lag luam marine thiab roj av hu ua Inconel 625.
Los ntawm kev hloov pauv ntawm lub tshuab hluav taws xob tsis zoo rau ultrasound thiab tawm thaum lub sijhawm luam ntawv, pab pawg kuj tau qhia txog yuav ua li cas cov ntu ntawm 3D cov ntawv luam tawm tuaj yeem ua nrog cov qauv sib txawv thiab cov ntawv sib txawv, muaj txiaj ntsig dab tsi'
Kawm txog tus kws sau ntawv ua ke thiab tus saib xyuas haujlwm, RMIT' s Tus Kws Qhia Tawm Suab Ma Qian, hais tias nws cia siab tias lawv cov lus cog tseg yuav ua rau muaj kev txaus siab tshwj xeeb rau cov cuab yeej tsim ua ultrasound rau luam ntawv 3D 3D.
& quot; Txawm hais tias peb siv cov titanium alloy thiab npib tsib xee superalloy, peb cia siab tias txoj kev tuaj yeem siv rau lwm cov khoom lag luam, xws li cov hlau tsis muaj hlau, cov hlau txhuas thiab cov khoom siv cobalt," Qian hais.
& quot; Peb cia siab tias cov txheej txheem no tuaj yeem tsim kom loj tuaj yeem ua kom 3D luam ntawv ntawm cov hlau feem ntau cov cuab yeej kev lag luam rau kev ua haujlwm siab dua lossis cov txheej txheem kev sib tw ntawm cov qib hlau."
