Khoom Taw qhia

Peb lub caij nplooj ntoos hlav nickel titanium yog lub caij nplooj ntoos hlav ua los ntawm cov khoom siv hlau ua los ntawm ob yam hlau: titanium thiab npib tsib xee. Nws muaj superelastic thiab zoo heev lub cim xeeb zog. Tom qab deformed los ntawm ib tug sab nraud quab yuam, lub caij nplooj ntoos hlav zoo li no tuaj yeem rov qab mus rau nws cov duab qub. Nws tuaj yeem paub qhov kev hloov pauv thiab rov qab los ntawm qhov sib txawv ntawm daim ntawv thov ib puag ncig raws li qhov kub thiab txias sab nraud, Cov duab cim xeeb muaj qhov hloov pauv hloov tau yooj yim, thiab kev cuam tshuam hnyav, thiab feem ntau yog siv hauv aviation, apparatus, hluav taws xob iav, chaw kho mob thiab ntau yam. .

Cov yam ntxwv ntawm nickel titanium springs:

cov nyhuv superelastic
Thaum cov duab nco alloy yog raug rau sab nraud quab yuam, nws yuav undergo yas deformation. Tom qab lub zog sab nraud raug tshem tawm, lub cim xeeb alloy yuav rov qab mus rau nws qhov qub. Cov nyhuv no yog hu ua cov nyhuv superelastic. Thaum cov duab nco alloy undergoes superelastic deformation, nws yuav induce martensitic transformation, thiab thaum lub sab nraud quab yuam raug tshem tawm, lub inverse Martensitic transformation yuav tshwm sim.

Damping yam ntxwv
Cov duab nco alloys tsim muaj ntau tus martensite variants nrog tib cov qauv thiab txawv orientations vim thermoelastic martensitic theem transformation, thiab lub zog interface ntawm cov variants thiab ntxaib interface zog nyob rau hauv lub martensite yog tsawg heev. Piv nrog Nws yog ib qho yooj yim rau migrate thiab muaj peev xwm zoo attenuate sab nraud mechanical zog xws li kev co thiab kev cuam tshuam. Yog li ntawd, cov duab nco alloys muaj qhov tshwj xeeb zoo damping zog thiab tuaj yeem siv los ua cov ntaub ntawv poob siab thiab cov khoom siv suab nrov.

Cov yam ntxwv tiv thaiv
Kev tshawb fawb qhia tau hais tias rau cov nickel-titanium alloys uas nws thawj qauv yog martensite, muaj ib tug linear kev sib raug zoo ntawm kuj thiab strain thaum lub sij hawm stretching txheej txheem; rau npib tsib xee uas nws cov qauv pib yog austenite los yog sib tov ntawm austenite thiab martensite, Rau titanium alloys, thaum muaj kev ntxhov siab vim kev hloov pauv martensitic tshwm sim, txoj kab nqes ntawm txoj kab nkhaus yuav txo qis, thiab kev sib raug zoo-kev sib raug zoo tseem nyob ua ntej thiab tom qab theem kev hloov pauv.
