Qhov sib txawv ntawm kev lag luam ntshiab titanium thiab titanium alloy rod daim ntaub ntawv
Titanium iodide, lub npe lag luam TAD: yog high-purity titanium tau los ntawm txoj kev iodination, yog li nws yog hu ua titanium iodide, los yog tshuaj dawb huv titanium. Txawm li cas los xij, nws tseem muaj cov ntsiab lus tsis huv xws li oxygen, nitrogen, thiab carbon, uas muaj kev cuam tshuam zoo rau cov khoom siv ntawm cov titanium ntshiab. Raws li purity ntawm titanium nce, lub zog thiab hardness ntawm titanium txo qis; yog li ntawd, nws yog yus muaj los ntawm: zoo tshuaj stability, tab sis tsis muaj zog.
Kev lag luam ntshiab titanium: Tsis zoo li tshuaj dawb huv titanium, kev lag luam ntshiab titanium muaj ntau cov pa oxygen, nitrogen, carbon thiab ntau yam ntawm lwm yam impurity (xws li hlau, silicon, thiab lwm yam). Nws yog cov ntsiab lus tsis tshua muaj alloy hauv qhov xwm txheej. Titanium alloy. Piv nrog rau cov tshuaj ntshiab titanium, nws lub zog yog zoo heev vim nws muaj ntau impurity ntsiab. Nws cov khoom siv kho tshuab thiab tshuaj lom neeg zoo ib yam li cov hlau tsis muaj steel (tab sis tseem muaj zog tsawg dua li titanium alloys).
Cov yam ntxwv ntawm kev lag luam ntshiab titanium yog: tsis tshua muaj zog, tab sis zoo plasticity, yooj yim rau txheej txheem, stamp, thiab vuam, thiab muaj machinability zoo; nws muaj cov khoom zoo hauv huab cua, dej hiav txwv, ntub dej chlorine, oxidizing, nruab nrab, thiab tsis muaj zog ntawm cov xov xwm. kev ua tau zoo. Kev tiv thaiv corrosion thiab oxidation kuj zoo dua li feem ntau austenitic stainless hlau; tab sis qhov kub tsis kam yog qhov tsis zoo, thiab kev siv kub yuav tsum tsis txhob siab dhau.
Kev lag luam ntshiab titanium muab faib ua peb qib: GR1, GR2, thiab GR23 raws li cov ntsiab lus impurity. Lub interstitial impurity ntsiab ntawm peb hom kev lag luam ntshiab titanium maj mam nce, yog li lawv cov neeg kho tshuab lub zog thiab hardness kuj maj mam nce, tab sis lub plasticity thiab toughness txo raws li. Cov khoom lag luam ntshiab titanium feem ntau siv hauv kev lag luam yog GR2 vim nws qhov nruab nrab corrosion tsis kam thiab cov khoom siv dav dav. GR23 tuaj yeem siv tau thaum hnav tsis kam thiab lub zog xav tau siab. GR1 tuaj yeem xaiv tau thaum xav tau kev ua haujlwm zoo dua.
Muaj cov ntshiab titanium feem ntau yog siv rau stamping qhov chaw thiab corrosion-resistant structural qhov chaw nrog ua hauj lwm kub hauv qab no 350 degree thiab tsis tshua muaj kev ntxhov siab tab sis yuav tsum tau zoo plasticity, xws li aircraft thav duab, tawv, cav accessories, thiab lwm yam .; seawater corrosion-resistant kav, li qub, thiab twj tso kua mis rau nkoj. thiab hydrofoils, desalination system Cheebtsam; chemical heat exchangers, twj tso kua mis, distillation yees, coolers, agitators, tees, impellers, fasteners, ion twj, compressor li qub thiab diesel cav pistons, txuas rods, daim hlau Huang thiab lwm yam.
-type titanium alloy, hom GR4 titanium pas nrig, Ti-4AL-0.005B titanium pas nrig, BT5 titanium pas nrig, GR6 titanium pas nrig: Hom alloy no yog nyob rau hauv ib-hom ib-theem xeev ntawm chav tsev kub thiab kev pabcuam kub, thiab tsis tuaj yeem ua kom muaj zog los ntawm kev kho cua sov (annealing yog Ib hom kev kho cua sov) uas feem ntau yog nyob ntawm cov khoom siv ntxiv dag zog. Lub zog kub ntawm chav tsev feem ntau qis dua -hom thiab - - hom titanium alloys (tab sis siab dua li kev lag luam ntshiab titanium), thaum kub siab (500-600 degree) lub zog thiab creep zog yog qhov siab tshaj plaws ntawm titanium alloys. Peb hom titanium alloys; Cov qauv ruaj khov, zoo oxidation tsis kam thiab vuam kev ua tau zoo, zoo corrosion kuj thiab txiav kev ua tau zoo, tab sis tsis tshua muaj plasticity (zoo thermoplasticity) thiab tsis zoo chav kub stamping kev ua tau zoo. Ntawm lawv, GR6 tau siv dav. Nws muaj nruab nrab mus rau siab zog thiab txaus plasticity nyob rau hauv lub xeev annealed. Nws muaj qhov zoo weldability thiab tuaj yeem siv qis dua 500 degree. Thaum cov ntsiab lus ntawm interstitial impurity ntsiab (oxygen, hydrogen, nitrogen, thiab lwm yam) yog tsis tshua muaj heev, nws kuj muaj zoo toughness thiab zoo txhua yam khoom ntawm ultra-tsawg kub, ua rau nws yog ib qho zoo heev ultra-low kub alloys.
Lub zog tensile ntawm GR4 yog me ntsis siab dua li ntawm kev lag luam ntshiab titanium thiab tuaj yeem siv los ua cov khoom siv hauv nruab nrab lub zog ntau yam. Feem ntau siv los ua vuam hlau hauv peb lub tebchaws.
Ti-4AL-0.005B thiab BT5 yog siv rau qhov chaw thiab vuam ua haujlwm hauv cov xov xwm corrosive hauv qab 400 degree, xws li cov tawv nqaij ntawm lub dav hlau, cov pob txha pob txha, cov tshuab compressor, cov hniav, cov nkoj nkoj, thiab lwm yam.
GR6 yog siv rau cov khoom siv thiab ntau yam molded qhov chaw ua haujlwm ntawm 500 degree rau lub sijhawm ntev, thiab tuaj yeem ncav cuag 900 degree rau kev siv sijhawm luv. Nws kuj tseem siv tau rau qhov kub tsis tshua muaj siab (-253 degree ) qhov chaw (xws li cov thawv ntim kub qis).
-type titanium alloy, hom TB2: Lub ntsiab alloying ntsiab ntawm hom alloy yog -theem stabilizing ntsiab xws li molybdenum, chromium, thiab vanadium. Thaum lub sij hawm normalizing thiab quenching, nws yog ib qho yooj yim rau khaws cia lub high-kub theem rau chav tsev kub thiab tau ib tug ruaj khov theem qauv, yog li nws yog hu ua -type titanium alloy.
-type titanium alloy tuaj yeem ua kom muaj zog los ntawm kev kho cua sov, muaj lub zog siab, thiab muaj kev vuam zoo thiab kev ua haujlwm siab; Txawm li cas los xij, nws qhov kev ua tau zoo tsis ruaj khov txaus, cov txheej txheem smelting yog qhov nyuaj, thiab nws daim ntawv thov tsis yog dav li -hom thiab - - hom titanium alloys.
Cov khoom uas tuaj yeem siv tau qis dua 350 degree feem ntau yog siv los tsim ntau yam phaj stampings thiab welded qhov chaw nrog kev kho cua sov tag nrho (khoom tov, kev laus); xws li compressor hniav, discs, shafts thiab lwm yam heavy-duty rotating qhov chaw, raws li zoo raws li aircraft qhov chaw, thiab lwm yam. TB2 alloy feem ntau yog xa mus rau hauv lub xeev kev daws teeb meem thiab siv tom qab kev daws kev laus.
Feem ntau siv qib ntawm titanium rods thiab titanium alloy titanium rods suav nrog BT3-1 titanium rods, TC9 titanium rods, thiab Ti-662 titanium rods: Hom alloy no nthuav tawm hom ob-theem qauv ntawm chav tsev kub, li no lub npe titanium alloy. Nws muaj cov cuab yeej zoo txhua yam, thiab feem ntau ntawm lawv tuaj yeem muaj zog los ntawm kev kho cua sov (tab sis TC1, TC2, thiab TC7 tsis tuaj yeem ntxiv dag zog los ntawm kev kho cua sov). Nws muaj zoo forging, stamping thiab vuam zog, tuaj yeem ua machined, muaj lub zog siab ntawm chav tsev kub, thiab muaj zog siab hauv qab 150-500 degree . Thaum tshav kub kub tsis kam, qee qhov (xws li TC1, TC2, TC3, TC4) kuj muaj qhov kub thiab txias toughness thiab zoo tiv thaiv dej hiav txwv kev nyuaj siab corrosion thiab kub ntsev kev nyuaj siab corrosion; qhov tsis zoo yog tias cov qauv tsis ruaj khov txaus.
