Muaj zog npaum li cas yog titanium alloy
Tntaub
Titanium yog ib qho tseem ceeb ntawm cov hlau tsim nyob rau hauv 1950s. Titanium alloys muaj lub zog siab, zoo corrosion kuj, thiab kub kub kuj ...
Thawj qhov ua tau zoo ntawm titanium alloy yog Ti-6Al-4V alloy ua tiav hauv Tebchaws Meskas hauv xyoo 1954. Vim nws cov cua sov ua haujlwm zoo, lub zog, plasticity, toughness, formability, weldability, corrosion kuj thiab biocompatibility, Nws yog qhov zoo dua thiab tau dhau los ua trump card alloy hauv kev lag luam titanium alloy. Kev siv cov alloy no suav nrog 75% mus rau 85% ntawm tag nrho cov titanium alloys. Ntau lwm cov titanium alloys tuaj yeem suav tias yog kev hloov kho ntawm Ti-6Al-4V alloy.
Dab tsi yog titanium alloy
Titanium alloy yog hais txog ntau yam hlau alloy uas ua los ntawm titanium thiab lwm yam hlau. Nws yog ib qho alloy uas muaj titanium ua lub hauv paus thiab lwm yam ntxiv. Muaj ob hom isomorphic crystals ntawm titanium: hauv qab 882 degree, nws yog -titanium nrog ib tug kaw-packed hexagonal qauv, thiab saum toj no 882 degree, nws yog -titanium nrog lub cev-centered cubic qauv.
Muaj zog npaum li cas yog titanium alloy
Titanium alloy tsis suav hais tias nyuaj, nws tsuas yog siab zog. Nws tsis tuaj yeem hais tias muaj lub zog siab, nws tsuas tuaj yeem hais tias muaj zog dua. Lub hardness ntawm titanium alloy yog qis dua li ntawm cov hlau quenched zoo tib yam (Kuv kuj xav ua ib rab titanium alloy ua ntej). Muaj cov pits), nws yuav ua tau zoo heev tom qab kev kho mob nitriding, tab sis nws tseem tsis nyuaj li silicon carbide, boron carbide thiab lwm yam high-hardness cov ntaub ntawv.
Siab zog
Qhov ceev ntawm titanium alloys feem ntau yog nyob ib ncig ntawm 4.51g / cm3, uas tsuas yog 60% ntawm cov hlau. Qee qhov muaj zog titanium alloys siab tshaj lub zog ntawm ntau cov qauv hlau alloy. Yog li ntawd, lub zog tshwj xeeb (lub zog / qhov ntom) ntawm titanium alloy yog ntau dua li ntawm lwm cov khoom siv hlau, thiab cov khoom uas muaj lub zog siab, zoo rigidity, thiab lub teeb yuag tuaj yeem tsim tau. Titanium alloys yog siv nyob rau hauv aircraft engine Cheebtsam, ncej, tawv, fasteners thiab tsaws iav.
High thermal siv
Qhov kev pabcuam kub yog ob peb puas degrees siab dua li ntawm aluminium alloys. Nws tseem tuaj yeem tuav lub zog xav tau ntawm qhov kub nruab nrab thiab tuaj yeem ua haujlwm ntev ntawm qhov kub ntawm 450 txog 500 degree. Ob hom titanium alloys tseem muaj lub zog siab nyob rau hauv thaj tsam ntawm 150 degree txog 500 degree. Lub zog tshwj xeeb, thaum lub zog tshwj xeeb ntawm aluminium alloy poob qis ntawm 150 degree. Kev ua haujlwm kub ntawm titanium alloy tuaj yeem ncav cuag 500 degree, thaum lub aluminium alloy qis dua 200 degree.
Cov ntsiab lus
Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis tsis tu ncua, daim ntawv thov kev lag luam ntawm titanium alloys yuav txuas ntxiv. Hauv aviation, aerospace, kev kho mob, lub zog thiab lwm yam kev lag luam, titanium alloys yuav txuas ntxiv ua si tag nrho rau lawv qhov zoo hauv lub teeb yuag, lub zog, kev tiv thaiv corrosion thiab lwm pab pawg, dhau los ua cov pob txha ntawm kev tsim khoom thiab engineering technology yav tom ntej.
Feem ntau hais lus, titanium alloys tau rov qab ua kom lub teeb thiab lub cev muaj zog, nrog rau kev nkag siab zoo ntawm ntau qhov chaw huab cua, thiab niaj hnub ua tus coj kev txhim kho ntawm cov ntaub ntawv tshawb fawb. Nyob rau hauv lub neej yav tom ntej, peb muaj laj thawj xav tias titanium alloys yuav twv yuav raug hu qhia lawv qhov tseeb lub zog nyob rau hauv ntau lub teb thiab txhawb kev tshawb nrhiav tsis tu ncua, innovation thiab kev vam meej ntawm noob neej.
