titanium steel composite phajTsis tsuas yog muaj kev tiv thaiv corrosion ntawm titanium, tab sis kuj muaj qhov zoo tshaj plaws weldability, formability thiab thermal conductivity ntawm carbon steel, thiab tseem txuag nqi titanium hlau. Titanium steel clad daim hlau yog dav siv nyob rau hauv marine kev lag luam, roj av kev lag luam, hluav taws xob fais fab thiab nuclear zog thiab lwm yam kev lag luam vim lawv ua tau zoo heev. Tam sim no, lub ntsiab ntau lawm txoj kev ntawmtitanium cladhlaudaim hlauyog txoj kev tawg cladding, tawg-dov cladding txoj kev thiab ncaj dov cladding txoj kev. Piv nrog rau txoj kev tawg cladding thiab txoj kev tawg-dov cladding, txoj kev ncaj dov cladding txoj kev tuaj yeem tsim clad daim hlau nrog cov phaj dav dav, nyias txheej thiab cov khoom sib xws. Ntawm ntau txoj hauv kev uas tau hais los saum no, vim muaj kev txwv ntawm kev sib txuas ntawm lub zog, tsuas yog tawg cladding tuaj yeem siv los npaj titanium-steel composite cov ntaub ntawv hauv kev tsim khoom. Lub ntsiab tseem ceeb txwv tsis pub lub zog sib txuas ntawm dov clad phaj yog tsim ntawm intermetallic tebchaw ntawm lub interface, thiab txoj kev kho saum npoo, dov kub, interface qauv thiab interfacial carbides yuav tag nrho cov cuam tshuam rau kev loj hlob ntawm intermetallic tebchaw.
Txhawm rau daws qhov teeb meem ntawm lub zog shear ntawm titanium-steel composite phaj, cov neeg ua ntej tau siv cov txheej txheem ntawm kev ntxiv cov hlau nruab nrab txheej los kho qhov sib txawv ntawm cov ntsiab lus sib txuas thiab txhim kho cov txiaj ntsig zoo ntawm kev sib txuas lub zog, xws li Ni. , V, Nb, Mo, Cu, IF steel thiab hlau ntshiab. Qhov sib ntxiv ntawm cov hlau interlayer daws qhov teeb meem ntawm kev tsim cov Fe-Ti tebchaw, tab sis nws tseem yuav ua rau muaj lwm yam teeb meem, yog li lub zog shear ntawm titanium-steel clad phaj tsis tuaj yeem txhim kho, lossis txawm tias qis dua. Hlau interlayers xws li Nb thiab Mo uas tuaj yeem ua rau tsis muaj qhov tsis txaus ntseeg nrog Ti tuaj yeem txuas tau zoo rau sab titanium ntawm titanium-steel clad phaj, tab sis kub dov ntawm 950 degree C yuav tsim ntau tus micropores ntawm kev sib tshuam nrog cov hlau. sab, Lub zog shear ntawm cov phaj sib xyaw yog txo; cov hlau interlayer nrog kev daws teeb meem nrog Ti, xws li Ni thiab Cu, yuav tsim ib qho tshiab intermetallic compound nrog titanium, yog li nws tsis tuaj yeem txhim kho lub zog shear ntawm titanium-steel composite phaj. , Rolling thiab compounding ntawm ntau tshaj 900 degree yuav txawm txo.
Tam sim no, nws yog qhov nyuaj rau xaiv cov txheej txheem nruab nrab uas tuaj yeem ua ke zoo nrog Fe thiab Ti interface qauv tib lub sijhawm. Siv cov khoom sib txuas TiC tsim nyob rau hauv cov txheej txheem kev npaj ntawm GR3 carbon steel yuav dhau los ua ib txoj hauv kev tseem ceeb los daws qhov kev sib txuas ntawm lub zog ntawm titanium-steel composite cov ntaub ntawv. Piv nrog Fe-Ti intermetallic tebchaw, TiC muaj cov khoom siv zoo dua qub, thiab tus qauv molar Gibbs dawb lub zog ntawm kev tsim TiC yog qis dua. Tam sim no, tsuas yog tso siab rau cov txheej txheem dov tsis tuaj yeem lav qhov ruaj khov ntawm TiC ntawm kev sib txuas lus. Thaum lub dov kub siab tshaj 850 degree, TiC yuav decompose nyob rau hauv qhov kev txiav txim ntawm thermal stress thiab tsis muaj nyob ruaj khov. Yuav kom TiC muaj nyob ruaj khov ntawm qhov sib cuam tshuam, qhov kub dov yuav tsum tau qis dua 850 degree, uas yuav ua rau ob qho teeb meem hauv kev siv tswv yim: ib qho yog tias qee cov carbides hauv cov khoom siv hauv paus tsis tuaj yeem yaj, uas cuam tshuam rau cov khoom siv hluav taws xob. cov khoom npaj; Qhov thib ob yog dov ntawm qhov kub hauv qab 850 degree. Tam sim no, feem ntau cov dov mills tau ntsib qhov teeb meem ntawm lub peev xwm dov tsis txaus. Nyob rau hauv cov ntsiab lus no, nws yog ib qho tsim nyog yuav tsum nrhiav kev sib xyaw interface tswj txoj hauv kev uas tuaj yeem ua kom muaj qhov sib xyaw dov kub thiab ua kom lub zog sib txuas ntawm lub interface.
(1) Tom qab hloov kho GR3 nrog Ga lub ntsiab lus, cov qauv kev sib txuas ntawm sab titanium yog -Ti, uas paub txog kev tswj hwm ntawm cov qauv sib txuas ntawm sab titanium, thiab qhov sib txawv ntawm Fe thiab C rau sab titanium yog txo qis.
(2) Tom qab kho cov qauv ntawm titanium sab interface, ib txheej TiC yog tsim los ntawm kev sib txuas lus. Ntawm 850-900 degree, qhov tuab ntawm TiC txheej tsis hloov pauv loj, uas yog 190 thiab 180nm raws, tab sis ib feem ntawm TiC dispersed ploj mus thiab dhau los ua cov txheej txheem TiC txuas ntxiv thiab sib npaug; Thaum qhov kub nce mus txog 950 degree, lub thickness ntawm TiC Qhov ntse nce yog 510nm.
(3) Lub zog shear ntawm titanium-steel clad phaj yog 225, 235, thiab 140MPa ntawm dov kub ntawm 850, 900, thiab 950 degree tom qab lub microstructure ntawm titanium-sab interface yog tswj. Thaum lub dov kub yog 900 degree, lub zog shear ntawm titanium-steel clad phaj tuaj yeem ua kom ntseeg tau thaum nce qhov kub ntawm cov titanium-steel clad phaj thiab txo lub nra ntawm cov khoom siv dov.
