TC17 titanium alloy thiab TI60 alloy txhua tus muaj txiaj ntsig zoo, kev siv vuam ntawm lawv cov ntaub ntawv los txhim kho kev ua haujlwm ntawm lub dav hlau. Daim ntawv no tshawb xyuas cov laser vuam technology ntawm 5 hli tuab tc17 thiab ua pob qij txha ntawm cov pob qij txha, thiab cov khoom xa tawm ntawm cov pob qij txha ntawm cov pob qij txha thiab cov khoom siv roj tsis zoo ntawm cov pob qij txha.
Lub TC17 titanium alloy yog tus cwj pwm siab thiab lub zog ua tau zoo, thiab haum rau cov khoom siv xws li cov tshuab hluav taws xob tsawg. Thaum lub TI60 alloy muaj cov creep tsis kam zoo thiab nkees muaj zog, thiab haum rau siv raws li kev kub siab compinks ntawm aero-engines thiab li ntawd. Vuam ob lub alloys tuaj yeem muab tag nrho ua si rau lawv cov txiaj ntsig thiab txhim kho txoj kev thrust-rau-hnyav piv ntawm lub dav hlau. Txawm li cas los xij, muaj ntau cov kev sib tw hauv vuam dissimilililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililililies Laser Laser Laser Laser Laser Laser Laser Laser
I. Cov ntaub ntawv sim thiab cov hau kev
Kev sim cov ntaub ntawv: 5mm tuab tc17 thiab Ti60 titanium alloy testic pieces tau xaiv raws li kev tshawb fawb.
Kev kho mob: tom qab txiav cov khoom xeem, tshem tawm cov npoo stains nrog tu cov tshuaj, tom qab ntawd so nrog ethanol thiab qhuav lawm.
Cov khoom siv vuam thiab cov txujci: Yls -4000}}}} fiber ntau fiber ntau laser thiab yaskaser vuam hlau tau siv rau laser vuam. Teeb lub Laser Fais, Kev Siv Hluav Taws Xob Las, Laser Deffocusing tus nqi thiab lwm yam kev tsis sib haum xeeb, thiab siv cov kev huv ntawm 99.99% Argon ua cov roj tiv thaiv.
Thib ob, cov txiaj ntsig kev sim thiab kev tshuaj xyuas
Macroscopic morphourity: Welded sib koom tes muaj peb ntu: Thaj Chaw Weld, cov khoom siv hluav taws xob, thiab cov khoom siv weld raws li tus lej X-puab. Muaj ntau ntau puag ncig metallurgical qhov tsis xws luag nyob rau hauv qis dua ntawm weld, thiab tsis muaj qhov porosity yog pom nyob rau sab qaum.
Microstructure: Microsalure ntawm TC17 titanium alloy paus hlau yog-ugase + eque -phas, thaum Ti60 Alloy Base Hlau yog yeej los ntawm Equiaxial. Qhov chaw ntawm Weld muaj ntau ntawm rab koob-zoo li theem nrab 'theem, thaum lub microstructure ntawm cov tshav kub-cuam tshuam txog kev hloov pauv.
Porosity qhov tsis xws thiab lawv cov yam ntxwv muab faib: muaj ntau qhov chaw nres tsheb muaj qhov tsis zoo ntawm Weld, thiab cov laj kab no yuav muaj cov txiaj ntsig ntawm cov khoom siv ntawm cov tshuab ntawm kev sib koom ua ke.
TENILILE THIAB NYIAM TXAUS SIAB Kev qaug zog ntawm cov pob qij txha: Tensile thiab cov pob qij txha tsis zoo los ntsuas cov khoom welded los ntsuas lawv cov khoom siv.
III. Cov lus xaus thiab cov zeem muag
Hauv daim ntawv no, lub laser vuam txoj kev kawm txog 5 hli tuab tc17 / ti60 dissimilar titanium qhia tau tag nrho cov kev tsis sib xws nyob hauv qab ntawm Weld. Microstructure tsom qhia tias qhov chaw ntawm Weld muaj ntau ntawm rab koob-zoo li ob theem 'phases, thaum lub microstructure ntawm lub tshav kub-cuam tshuam li cas. Cov txiaj ntsig ntawm lub tensile thiab cov roj ntsha tsis muaj zog rog tau pom tias cov khoom siv tshuab hluav taws xob tau cuam tshuam los ntawm Weld Porosity thiab Microstructure. Kev tshawb fawb ntxiv yuav ua rau yav tom ntej los ua kom zoo dua cov khoom siv vuam thiab cov txheej txheem los txhim kho cov cuab yeej siv thiab kev ntseeg tau ntawm welded pob qij txha.
