Pab Pawg Tshawb Fawb Txog Kev Tshawb Fawb ntawm Liangjiang Collaborative Innovation Zone kov yeej cov teeb meem hauv thaj tsam ntawm Alloys

Pab pawg tshawb fawb tshawb fawb ntawm Liangjiang Collaborative Innovation Zone kov yeej cov teeb meem hauv thaj tsam ntawm cov hlau

Tsis ntev los no, Chongqing Liangjiang Collaborative Innovation Zone tau nyob hauv lub tsev kawm ntawv qib siab. Lub siab kub creep zog ntawm cov alloy yog txhim kho.

Nws yog to taub tias alloy muaj tsawg ntom ntom, lub zog muaj zog thiab kub zoo heev oxidation tsis kam thiab creep resistance. Nws yog ib qho khoom siv hluav taws xob kub kub hauv qhov kev pabcuam kub ntawm 650-850 degree . thiab lwm qhov chaw kub-tiv taus muaj kev thov dav dav.

Raws li tus neeg sawv cev ntawm peb tiam -TiAl alloy, txawm hais tias qhov kev pabcuam kub ntawm TNM alloy tuaj yeem ncav cuag 750 degree, qhov kub tsis txaus siab yog txias rau hauv chav tsev kub thiab hloov mus rau qhov kev txiav txim 0 theem. , uas yog muab faib rau hauv ( 2 ntxiv ) Nyob rau hauv lub interface ntawm lamellar pawg, nyob rau hauv high kub kev pab cuam tej yam kev mob, cov ntsiab lus ntawm 0 theem tsis tsuas yog nce, tab sis kuj precipitates lub nyuaj thiab ω theem. Nrog rau qhov sib txuam ntawm creep deformation, qhov nyuaj thiab nkig 0/ 0(ω) thiab strain incongruity ntawm ib puag ncig 2/ nplooj ntawv ua rau muaj kev ntxhov siab, uas muab qhov chaw nucleation rau qhov thiab cov kab nrib pleb, thiab exacerbates creep tsis ua hauj lwm.

Yuav ua li cas tswj qhov loj me, cov ntsiab lus thiab kev faib tawm ntawm / 0 theem thiab txhim kho microstructure stability yeej ib txwm yog ib qho teeb meem kub hauv thaj tsam ntawm -TiAl alloys.

Pab neeg ntawm Prof. Hongchao Kou tau ua tiav tiav daim ntawv TNM alloy los ntawm kev siv cov hmoov kub isostatic nias txoj kev. Tom qab kev laus kev kho mob ntawm 1050 degree / 2h, ib tug me me ntawm finely dispersed 0 theem yog precipitated nyob rau hauv lub 2/ lamellae, uas ho txhim kho lub siab kub creep ntawm lub alloy. kev ua haujlwm sib txawv.

Nws kuj tseem nkag siab tias tus xibfwb Kou Hongchao tam sim no yog tus kws tshaj lij hauv Chongqing Lianghang Hlau Khoom Co., Ltd. Tam sim no, thawj theem ntawm kev lag luam kev lag luam ntawm Chongqing Ob Lub Tuam Txhab tau ua tiav thiab muab tso rau hauv kev siv, thiab kev teeb tsa thiab kev ua haujlwm tau ua tiav. Nws cia siab tias thawj pawg ntawm cov khoom yuav raug xa mus rau cov neeg siv khoom thaum ntxov xyoo tom ntej.

Kev vam khom rau cov thev naus laus zis tseem ceeb ntawm titanium alloy casting kev lag luam, Chongqing Ob Airlines tsom mus rau kev tawg los ntawm kev siv tshuab raj txwv tsis pub tsim cov khoom tseem ceeb ntawm cov khoom siv high-end, thiab ua kom muaj kev ywj pheej ntawm cov khoom tseem ceeb hauv aviation, aerospace, riam phom. , nuclear kev lag luam, thiab kev tsheb ciav hlau. Tom qab qhov project tau muab tso rau hauv kev tsim khoom, nws yuav raug tsim los nrog Cov kev cuam tshuam tseem ceeb ntawm titanium alloy aerospace qhov tseem ceeb precision tsim thiab "kev tshawb fawb ua ntej, cov ntxaib digital, kev sim, kev sim tsav, kev ua kom zoo dua qub thiab cov nqi qis qis" tag nrho. , kev lag luam daim ntawv thov-oriented "tsim-university-kev tshawb fawb-siv" advanced Lub chaw tsim khoom pab Chongqing los ua ib lub ntiaj teb-class manufacturing puag rau qhov tseem ceeb ntawm aerospace thiab high-end khoom.
