Composite tsim ntawm multivariate multiscale reinforced titanium matrix composites

Nrog rau txoj kev loj hlob ntawm Tuam Tshoj lub aerospace thiab aviation technology, qhov yuav tsum tau rau cov khoom siv nyob rau hauv hnyav kev pab cuam ib puag ncig, xws li toughness, yog nce. Ntawm ntau cov ntaub ntawv, txuas ntxiv siv cov khoom siv titanium matrix rau cov kws tshawb nrhiav vim tias lawv cov khoom siv kub, thiab lwm yam kev tshawb fawb zoo tshaj 30 xyoos thiab optimisation, ntau ntau qhov kev txhawb nqa titanium matrix composites tau tsim. Tom qab ntau tshaj 30 xyoo ntawm kev tshawb fawb thiab kev ua kom zoo, ntau yam titanium matrix composites uas paub tab tau tsim, thiab kev ua tau zoo ntawm cov ntaub ntawv tau ua tiav zoo. Piv nrog rau titanium alloy matrix, kev siv kub ntawm titanium matrix composites yuav nce 100 ~ 150 degree los ntawm tsim nyog tsim thiab ua, thiab lub zog yuav nce los ntawm ntau tshaj 100 MPa nyob rau tib lub kub, uas yuav tsum tau hloov lub tsoos high-temperature hlau cov ntaub ntawv nyob rau hauv high-temperature kev pab cuam ib puag ncig kom ua tiav qhov hnyav txo.
Nyob rau hauv xyoo tas los no, lub tswv yim ntawm cov khoom siv tshiab tsim theories xws li multivariate multi-scale reinforcement thiab bionic qauv reinforcement tau muab cov tswv yim tshawb fawb tshiab los txhim kho kev ua tau zoo ntawm titanium matrix composites, thiab kev npaj cov txheej txheem ntawm multivariate multi-scale reinforcement ntawm titanium matrix. Composites uas paub tab ntau dua nyob rau hauv daim ntawv thov tam sim no yog nyob rau hauv-situ autogenous thiab hmoov metallurgy. Nyob rau hauv situ autogenous thev naus laus zis tuaj yeem ua rau micro / nano reinforcement uniformly faib nyob rau hauv cov matrix thiab tau zoo heev interfacial qauv thiab interfacial zog !0; hmoov metallurgy thev naus laus zis tuaj yeem ua rau lub zog txhawb nqa tsis sib xws hauv cov matrix nrog cov qauv tsim los ntawm kev tsim ua ntej xws li kev sib xyaw thiab tso cov hmoov, uas ua rau kom muaj kev tsim cov khoom siv. Yog li, cov txheej txheem 2 no tau ua tiav ntau yam kev siv hauv kev npaj titanium matrix composites.
Nyob rau hauv daim ntawv no, peb yuav tshuaj xyuas cov xwm txheej tam sim no ntawm kev tshawb fawb thiab kev siv cov titanium matrix composites los ntawm cov yam ntxwv ntawm kev tsim cov tswv yim sib xyaw, kev siv thev naus laus zis, cov khoom siv kho tshuab thiab kev siv engineering ntawm ntau qhov sib txawv ntawm ntau qhov kev txhawb zog titanium matrix composites, thiab muab tso rau pem hauv ntej lub peev xwm. Kev tshawb fawb ntawm cov khoom siv no, nrog rau kev saib xyuas ntxiv txhim kho kev ua tau zoo ntawm titanium matrix composites, daws cov teeb meem ua haujlwm ntawm titanium matrix composites thiab yog li txhawb cov titanium matrix composites "Kev sib xyaw ua ke ntawm kev tsim, kev npaj, tsim thiab kev siv ntawm titanium matrix. sib xyaw.
Tuam Tshoj tus titanium matrix composites tom qab lub sij hawm ntev ntawm kev tshawb fawb thiab kev loj hlob, twb muaj ib tug paub tab cov ntaub ntawv system thiab npaj technology, cov kev ua tau zoo ntawm cov khoom tau zoo heev. Txhawm rau txhawm rau txhim kho qhov kev ua tau zoo ntawm titanium matrix composites, los daws cov teeb meem kev ua haujlwm ntawm titanium matrix composites, thiaj li ua tiav kev sib koom ua ke ntawm titanium matrix composites "tsim-kev npaj-forming-application", yav tom ntej kev taw qhia ntawm kev tshawb fawb thiab txoj kev loj hlob yuav tsum tau tsom rau cov ntsiab lus hauv qab no.
(1) "micro-nano + configuration" toughening tsim: los ntawm kev tsim ntawm titanium matrix composite reinforcing lub cev hom, qhov loj, faib thiab qauv, kom ua tau raws li qhov tsis sib xws ntawm kev faib tawm ntawm lub cev reinforcing, ua lub luag haujlwm ntawm kev txhawb nqa lub cev thiab configuration synergistic toughening, ua txhaum los ntawm cov khoom sib xyaw lub zog-yas toughness ntawm inversion ntawm cov kev txwv ntawm kev ruaj ntseg ntawm cov khoom siv, tsim ib hom tshiab ntawm siab zog thiab siab toughness titanium matrix composites. Ib hom tshiab ntawm high-strength thiab high-toughness titanium matrix composites yog tsim.
(2) Ua tiav qhov kev tsim thiab kev tswj xyuas meej ntawm lub koom haum los ntawm kev siv thev naus laus zis thev naus laus zis: sib sib zog nqus cov kev tshawb fawb ntawm cov txheej txheem thermal thiab cov txheej txheem ntawm titanium matrix composites, tshawb xyuas qhov cuam tshuam ntawm kev txhawb zog, kev tsim thawj zaug, kev teeb tsa sab hauv thiab lwm yam ntawm thermal deformation. mechanism ntawm titanium matrix composites, tsim kom muaj kev ua tiav thermal ua tiav, ua tiav kev tswj xyuas cov khoom siv sib xyaw ua ke, thiab thawb rau pem hauv ntej daim ntawv thov ntawm isothermal forging thev naus laus zis hauv kev npaj cov khoom siv loj loj. Daim ntawv thov.
(3) Stabilized npaj ntawm high-end high-performance Cheebtsam ntawm titanium matrix composites: exerting qhov zoo ntawm kev npaj technology thiab advanced ua txhais tau tias, txais kev sib txuas ntawm in-situ autogenous technology, laser cladding technology thiab additive manufacturing technology (3D printing) los tsim cov kev npaj thiab tom qab ua tiav technology ntawm cov ntaub ntawv sib xyaw xws li precision me me Cheebtsam, structurally complex Cheebtsam thiab lwm yam high-end Cheebtsam, thiaj li ua kom titanium matrix composites ua tau raws li cov kev xav tau ntawm kev txiav-ntug teb nyob rau hauv cov nqe lus ntawm kev ua tau zoo thiab precision. cov kev xav tau nyob rau hauv kev txiav-ntug teb.
(4) Txhim kho tus nqi qis thiab ua haujlwm siab titanium matrix cov ntaub ntawv sib xyaw npaj thiab ua cov thev naus laus zis, txhim kho tus nqi ntawm cov khoom, txo qhov pib ntawm kev siv titanium matrix cov ntaub ntawv sib xyaw, thiab paub txog daim ntawv thov ntawm titanium matrix composite cov ntaub ntawv los ntawm daim teb. ntawm tub rog kev lag luam mus rau thaj tsam ntawm kev lag luam pej xeem.
