Lub cim xeeb zoo: Lub cim xeeb zoo yog hais txog qhov tshwm sim uas cov khoom siv, xws li Nitinol, tuaj yeem rov qab tau nws cov duab qub tom qab tau deformation. Qhov no tshwm sim los ntawm thermally induced theem transformation txheej txheem. Thaum cov theem niam txiv txias hauv qab qhov kub ntawm Mf, tsim martensite, thiab tom qab ntawd deformed ntawm qhov kub hauv qab Mf, nws tuaj yeem rov qab mus rau nws qhov qub qub thaum cua sov hauv qab Af kub.
Superelasticity: Superelasticity, tseem hu ua pseudoelasticity, piav qhia txog lub peev xwm ntawm cov khoom siv los nthuav tawm cov kab mob loj loj rov qab los ntawm cov rog sab nraud. Tsis zoo li lub cim xeeb zoo, superelasticity tsis cuam tshuam nrog cov teebmeem thermal. Thaum raug kev ntxhov siab, cov hlau ua rau muaj kev ntxhov siab vim kev hloov pauv martensitic thaum nyob hauv niam txiv theem, ua rau tus cwj pwm txawv ntawm cov khoom siv tib yam. Nws txoj kev txwv tsis pub dhau ntau tshaj li cov khoom siv ib txwm siv, thiab nws tsis ua raws li Hooke Txoj Cai.
Nyob rau hauv kev sib piv rau lub cim xeeb zog, superelasticity tsis cia siab rau qhov kub thiab txias hloov. Hyperelasticity yog hais txog tus cwj pwm kev ntxhov siab nyob rau hauv ib qho kev deformation tshwj xeeb, qhov twg kev ntxhov siab tsis nce proportionally nrog strain. Hyperelasticity tuaj yeem muab faib ua linear lossis nonlinear. Linear hyperelasticity nthuav tawm qhov kev ntxhov siab-txoj kev sib raug zoo nyob ze rau linear, thaum nonlinear hyperelasticity cuam tshuam nrog kev ntxhov siab vim kev hloov pauv martensitic thiab nws qhov thim rov qab thaum thauj khoom thiab tshem tawm, feem ntau hu ua kev hloov pauv pseudoelasticity.
Sensitivityto Intraoral Temperature Change: Stainless hlau thiab CoCr alloy orthodontic xov hlau feem ntau tsis cuam tshuam los ntawm kev hloov hauv qhov kub thiab txias. Txawm li cas los xij, lub zog orthodontic exerted los ntawm superelastic npib tsib xee-titanium alloy orthodontic hlau tuaj yeem sib txawv nrog qhov ncauj kub.
Thaum tus nqi deformation tseem nyob tas li, qhov nce hauv qhov kub thiab txias ua rau lub zog rov qab los. Qhov no tuaj yeem ua kom cov hniav txav los ntawm kev txhawb cov ntshav ntws hauv cov hlab ntsha uas cuam tshuam los ntawm cov khoom siv orthodontic. Cov ntshav ntws nce ntxiv nourishes kho cov hlwb, tswj lawv qhov tseem ceeb thiab ua haujlwm zoo. Txawm li cas los xij, cov kws kho hniav tuaj yeem ntsib cov teeb meem hauv kev tswj xyuas los yog ntsuas lub zog orthodontic hauv qhov ncauj ib puag ncig.

Corrosion Resistance: Cov kev tshawb fawb qhia tias qhov corrosion kuj ntawm nickel-titanium hlau yog piv rau cov hlau stainless hlau.
Biocompatibility: Nickel-titanium duab nco alloy, xws li Nitinol, muaj cov tshuaj lom neeg muaj pes tsawg leeg, muaj cov atomic alloys xws li npib tsib xee-titanium nrog kwv yees li 50% nickel cov ntsiab lus. Nickel paub tias muaj cov kab mob carcinogenic thiab mob qog noj ntshav. Txawm li cas los xij, txheej txheej ntawm titanium oxide ua raws li kev thaiv, ua rau muaj kev sib raug zoo ntawm Ni-Ti alloys.
