Piv nrog rau lwm cov ntaub ntawv hlau, titanium alloys muaj qhov zoo hauv qab no:
1. Lub zog tshwj xeeb (lub zog tensile / ntom) yog siab (saib daim duab), lub zog tensile tuaj yeem ncav cuag 100 ~ 140kgf / mm2, thiab qhov ceev tsuas yog 60% ntawm cov hlau.
2. Lub zog nruab nrab kub zoo, kev siv kub yog ntau pua degrees siab dua li ntawm aluminium alloy, 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 ~ 500 degree.
3. Zoo corrosion kuj, ib tug niaj hnub thiab ntom oxide zaj duab xis yog tam sim ntawd tsim nyob rau ntawm qhov chaw ntawm titanium nyob rau hauv cov huab cua, thiab nws muaj peev xwm tiv taus qhov yaig ntawm ntau yam xov xwm. Feem ntau, titanium muaj corrosion kuj zoo nyob rau hauv oxidizing thiab nruab nrab xov xwm, thiab zoo corrosion kuj nyob rau hauv seawater, ntub chlorine thiab chloride daws. Txawm li cas los xij, hauv kev txo cov xov xwm, xws li hydrochloric acid, titanium muaj kev tiv thaiv corrosion tsis zoo.
4. Titanium alloys uas muaj qhov kub thiab txias tsis zoo thiab tsis tshua muaj kev cuam tshuam cov ntsiab lus, xws li TA7, tuaj yeem tswj tau qee yam plasticity ntawm -253 degree .
5. Tsawg elastic modulus, me me thermal conductivity, tsis muaj ferromagnetism.
6. Siab hardness.
7. Tsis zoo stamping thiab zoo thermoplasticity.
Kev kho cua sov Titanium alloys tuaj yeem tau txais cov txheej txheem sib txawv thiab microstructures los ntawm kev kho cov txheej txheem kho cua sov. Nws feem ntau ntseeg tau tias cov qauv zoo equiaxed muaj cov yas zoo, thermal stability thiab qaug zog, cov qauv acicular muaj zog durability, creep zog thiab tawg toughness, thiab equiaxed thiab acicular mix qauv muaj cov khoom zoo.
Feem ntau siv cov kev kho cua sov yog annealing, kev daws thiab kev laus kev kho mob. Annealing yog tshem tawm cov kev ntxhov siab sab hauv, txhim kho plasticity thiab microstructure stability kom tau txais cov khoom zoo dua. Feem ntau, annealing kub ntawm alloy thiab (+) alloy yog xaiv ntawm 120 ~ 200 degree hauv qab qhov kev hloov pauv ntawm (+) -→ theem; Feem ntau, quenching ntawm (+) alloys yog nqa tawm ntawm 40 ~ 100 degree hauv qab ntawm ( + ) - → theem hloov chaw, thiab quenching ntawm sub-stable alloys yog nqa tawm ntawm 40 ~ 80 degree saum toj no (+) - → theem hloov chaw. Kev laus kub yog feem ntau 450 ~ 550 degree. Tsis tas li ntawd, txhawm rau ua kom tau raws li cov kev xav tau tshwj xeeb ntawm cov khoom ua haujlwm, cov txheej txheem kev kho cua sov hlau xws li ob chav annealing, isothermal annealing, kev kho cua sov, thiab kev kho cua sov deformation kuj tau siv hauv kev lag luam.
