Siab siv
Qhov ceev ntawm titanium alloys feem ntau yog nyob ib ncig ntawm 4.51g / cm3, uas tsuas yog 60% ntawm cov hlau, thiab qee qhov muaj zog titanium alloys siab tshaj lub zog ntawm ntau cov hlau alloy steel. Yog li ntawd, lub zog tshwj xeeb (lub zog / 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 lub cav Cheebtsam, skeletons, tawv, fasteners thiab tsaws iav ntawm aircraft.
High thermal siv
Kev siv kub yog ntau pua degrees siab dua li ntawm aluminium alloy, thiab nws tseem tuaj yeem tswj tau lub zog xav tau ntawm qhov kub nruab nrab, thiab tuaj yeem ua haujlwm ntev ntawm qhov kub ntawm 450 ~ 500 degree. Ob hom titanium alloys tseem muaj lub zog tshwj xeeb hauv thaj tsam ntawm 150 degree ~ 500 degree, thaum lub zog tshwj xeeb ntawm aluminium alloy txo qis ntawm 150 degree. Kev ua haujlwm kub ntawm titanium alloys tuaj yeem ncav cuag 500 degree, thaum aluminium alloys tuaj yeem ncav cuag qis dua 200 degree.
Zoo corrosion kuj
Titanium alloy ua haujlwm nyob rau hauv huab cua huab cua thiab dej hiav txwv nruab nrab, thiab nws cov corrosion kuj zoo dua li ntawm cov hlau tsis muaj steel, thiab nws tsis kam rau pitting, acid etching, thiab kev ntxhov siab corrosion yog tshwj xeeb tshaj yog muaj zog, thiab nws muaj corrosion kuj zoo heev rau alkali, chloride, chlorine organic teeb meem, nitric acid, sulfuric acid, thiab lwm yam. Txawm li cas los xij, titanium tsis zoo corrosion kuj los txo cov pa oxygen thiab chromium ntsev media.
Kev ua tau zoo ntawm qhov kub thiab txias
Titanium alloys tseem tuaj yeem tswj hwm lawv cov khoom siv dag zog ntawm qhov qis thiab ultra-tsawg kub. Titanium alloys uas muaj qhov kub thiab txias zoo heev thiab cov ntsiab lus tsis sib xws, xws li TA7, tuaj yeem tswj tau qee yam plasticity ntawm -253 degree . Yog li ntawd, titanium alloy kuj yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob qis.
Tshuaj active
Titanium muaj cov tshuaj lom neeg zoo heev thiab ua rau muaj zog tshuaj lom neeg nrog O2, N2, H2, CO, CO2, dej vapor, ammonia, thiab lwm yam hauv huab cua. Thaum cov ntsiab lus carbon ntau dua 0.2%, TiC nyuaj yuav tsim nyob rau hauv titanium alloy, thiab thaum kub siab, lub hard txheej txheej ntawm TiN kuj yuav tsim los ntawm kev sib cuam tshuam nrog N, thiab Thaum cov ntsiab lus carbon siab tshaj 600 degree, titanium yuav nqus cov pa oxygen los ua txheej txheej tawv tawv nrog cov tawv tawv siab, thiab cov txheej brittleness kuj yuav tsim thaum cov ntsiab lus hydrogen nce. Qhov tob ntawm txheej txheej tawv thiab nkig tsim los ntawm kev nqus roj tuaj yeem ncav cuag 0.1 ~ 0.15 hli, thiab qib hardening yog 20% ~ 30%. Titanium kuj muaj cov tshuaj lom neeg muaj txiaj ntsig zoo, thiab nws yooj yim rau kev ua raws li kev sib txhuam ntawm qhov chaw.
