Raws li ib qho zoo tshaj plaws cov khoom siv hlau ua kom zoo nkauj rau cov tswv yim txhim kho niaj hnub ntawm kev txhim kho lub tswv yim niaj hnub, kev txuag hluav taws xob thiab emission txo. Nws daim ntawv thov kev cia siab hauv Aerospace, tsheb thauj mus los, sib txuas lus hluav taws xob thiab lwm yam kev lag luam tau nce qib. Txhawb nqa cov ntawv thov ntxiv thiab dav ntawm cov alloys Magnesium hauv ntau thaj teb tseem xav tau kev txhim kho kev siv thev naus laus zis. Vuam yog qhov tseem ceeb ntawm kev sib txuas txuas rau hauv kev tsim cov khoom siv cov khoom siv tsis xws luag thiab kev kho cov khoom lag luam tsis xws luag. Qhov teeb meem kev sib txuas ntawm cov hlau nplaum sib txuas nrog cov hlau qub thiab cov medimailarar tau txuas ntxiv tau txais kev saib xyuas nyob rau xyoo tas los no.
Piv nrog rau lwm cov vuam txoj kev vuam, laser vuam muaj ntau yam zoo xws li muaj kev pheej hmoo siab, qis dua cov kev ntxhov siab thiab qhov chaw kub nqaim. Yog li ntawd, nws yog lub thev naus laus zis nrog kev muaj peev xwm rau kev sib txuas ntawm cov khoom siv magnesium. Txawm li cas los xij, microstructure ntawm magnesium alloy laser welded pob qij txha feem ntau yog feem ntau tsis muaj zog tshaj li ntawm niam txiv cov khoom. Qhia kev sib raug zoo ntawm microstructure thiab kev coj ua ke tshuab ntawm laser welded pob qij txha yog qhov ua kom zoo rau cov qauv ntawm cov hlau nplaum thiab ua tiav kev sib koom tes ua haujlwm siab.
Welded sib koom tes ntawm Magnesium Alloy Az80 muaj cov cheeb tsam Fuster (FZ), kub li cas) thiab cov khoom siv hluav taws xob (BM). Cov khoom siv hauv paus yog muaj cov muaju equatalals nrog cov qoob loo zoo, qhia kev ua yeeb yam kev tawm tswv yim kev ntxhib los mos. Cov kab ke nplej ntawm lub chaw weld yog random, thiab microstructure zoo ib yam li cov qauv casting, uas yog tshwm sim los ntawm cov txheej txheem casting thiab crystallization txheej txheem thaum vuam. Ib qho ntxiv, lub chaw weld precipitates ib qho kev txuas ntxiv ntawm MG17Ates thaum lub sijhawm Solmemification. Nyob rau hauv lub laser welded sib koom ua ke ntawm Az80 Magnesium Alloy, Thaj Chaw Sib Tw Kub nrog li 60μm yog tsim kom meej meej ntawm Weld cheeb tsam thiab cov khoom siv. Cov noob nplej loj ntawm cov cua sov tuaj thaj chaw zoo ib yam li ntawd ntawm cov khoom siv hauv paus, tab sis nws cov hmoov nplej tau muab ntau ncha. Tsis tas li ntawd, muaj ntau tus ntawm cov nplua thiab dispersed mg17al12 theem nyob rau hauv cov cua sov kev cuam tshuam thaum lub sijhawm vuam.
Welded sib koom tes ntawm Magnesium Alloy AZ80 qhia meej cov khoom siv zoo nkauj, nrog cov txiaj ntsig zoo ntawm 202 MPA thiab ib qho kev ua haujlwm sib tw ntawm txog li 92%. Micma iSructiverration los ntawm Epma thiab EBSD sib koom ua ke nrog cov txheej txheem sib txawv ntawm Weld sib koom ua ke yog lub zog muaj zog ntxiv dag zog ntawm cov laser worded magnesium alloys. Cov kev sib txuas ntawm Orowan ntxiv dag zog rau, Heterogeneous deforming ua rau cov neeg kho tshuab ntawm AZ80 Magnesium Weld pob qij sib piv nrog cov niam txiv cov khoom.
