Thawj lo lus tseem ceeb: nickel-titanium alloy zoo nco alloy yam ntxwv muaj nuj nqi
Nickel-titanium alloy zoo li ncocov khoom siv yog cov khoom siv tshwj xeeb uas ua ke nrog kev paub thiab kev ua haujlwm, thiab cov khoom siv nickel-titanium alloy nco nco alloy yog ib qho tseem ceeb ntawm cov khoom siv nickel-titanium alloy zoo li nco. Nitinol cov duab nco alloy yog hais txog ib chav kawm ntawm cov alloys uas nws cov duab nyob rau hauv ib qho kev pib lub xeev, tom qab deformed mus rau lwm cov duab los ntawm cov yas deformation uas tsis kub kub, thiab ces rhuab thiab lwm yam txhais tau tias kom kub thiab re-deform mus rau lub qub duab.
1. Cov yam ntxwv ntawm Nitinol Shape Memory Alloys
(1) Lub cim xeeb zoo
Nitinol cov duab nco alloys yuav cia li rov qab lawv cov duab tom qab kev kho cua sov. Qhov kev hloov pauv no yog cov duab nco cov yam ntxwv ntawm Nitinol cov duab nco alloys. Lub cim xeeb tuaj yeem muab faib ua ib-txoj kev nco, ob-txoj kev zoo lub cim xeeb thiab tag nrho-course shape memory raws li txoj cai rov qab.
(2) Hyperelasticity
Nickel-titanium duab nco alloys yuav deform thaum raug rau sab nraud quab yuam, thiab yuav rov qab mus rau lawv cov qub duab tom qab tshem tawm sab nraud rog. Qhov no yog superelasticity ntawm nickel-titanium zoo nco alloys. Tom qab superelastic deformation ntawm NiTi alloy duab nco alloy, nws yuav ncaj qha mus rau martensitic transformation, thiab tshem tawm sab nraud quab yuam, nws yuav ua rau reverse martensitic transformation.
(3) Damping
Nitinol cov duab nco alloys muaj cov khoom damping zoo heev vim yog kev hloov kho tus kheej ntawm theem kev hloov pauv thiab qhov cuam tshuam thiab cov lus tsa suab tsim nyob rau hauv theem kev hloov.
(4) Kev tiv thaiv
Thaum lub sij hawm deformation txheej txheem ntawm martensitic npib tsib xee-titanium alloy zoo nco alloy, muaj ib tug linear kev sib raug zoo ntawm cov kuj thiab cov strain. Thaum lub sijhawm hloov pauv tshwm sim, txoj kab nqes ntawm txoj kab nkhaus yuav txo qis, txawm li cas los xij, nws yuav tuav txoj kev sib raug zoo ua ntej thiab tom qab theem martensite.
Thib ob, lub luag haujlwm ntawm nickel-titanium alloy zoo li nco alloy
Txij li thaum Nitinol zoo nco alloy muaj qhov tshwj xeeb ua haujlwm ntawm Nitinol zoo nco alloy, nws kuj muaj qhov zoo ntawm superelasticity, hnav tsis kam thiab corrosion kuj, yog li nws tau siv dav hauv ntau lub teb.
(1) Mechanical Engineering
Kev siv cov nickel-titanium zoo nco alloys hauv kev lag luam machinery yog thawj zaug hauv cov yeeb nkab txuas thiab fasteners. Tshwj xeeb, ntawm kev sib txuas ntawm cov khoom siv kho tshuab, cov kav dej, thiab lwm yam, thiab qhov sib txuas ntawm lub dav hlau refueling nyob rau hauv cov huab cua, nickel-titanium alloy zoo nco alloy yog siv los ua cov casing nrog ib txoj kab uas hla sab nraud uas yog 3 feem pua loj tshaj qhov puab txoj kab uas hla, thiab expansion ntawm lub casing yog ua nyob rau hauv ib tug tej yam kub thiab txias. Txoj kab uas hla yog li 8 feem pua. Nyob rau hauv lub rooj sib txoos, lub casing yog tshem tawm los ntawm cov kua nitrogen, thiab lub raj yog ntxig los ntawm ob qho kawg. Yog tias qhov ntsuas kub nce mus rau qhov ntsuas kub ib txwm, qhov ntsuas kub tuaj yeem hloov pauv los ntawm hluav taws xob cua sov, thiab cov duab nco alloy ntawm cov nickel-titanium alloy ntawm huab cua refueling interface yog deformed, thiab cov nickel-titanium alloy yog deformed. Lub casing ua los ntawm cov duab nco alloy shrinks los tsim ib lub kaw ntom nti, thiaj li ua kom nruj thiab tsis muaj roj to, thiab cov nyhuv yog ntau dua li cov tsoos vuam. Yog li ntawd, Nitinol zoo li nco alloys yog tshwj xeeb tshaj yog haum rau aerospace, nkoj, roj pipelines thiab lwm yam teb. Nyob rau hauv qhov chaw uas kev tsim kho tsis yooj yim, cov pins tuaj yeem ua los ntawm nickel-titanium zoo li nco alloys thiab ntsia rau hauv qhov rau cua sov. Yog li ntawd, qhov ntsuas kub ntawm cov nickel-titanium alloy zoo li lub cim xeeb alloys yog siv los tsav ntau lub zog los ua cov neeg hlau, kev tswj xyuas, thiab lwm yam.
(2) Kev tsim kho kev lag luam
Raws li tau hais los saum toj no, ntau yam ntxwv ntawm Nitinol cov duab nco alloys, ua ke nrog cov qauv ntawm Nitinol cov duab nco alloys, tuaj yeem txhim kho qhov damping ntawm lub cev thiab txo cov lus teb ntawm cov qauv, yog li tsim ntau hom damping zog dissipation li. Nws tseem tuaj yeem tsim cov kev co cais tawm los ntawm kev siv Nitinol cov duab nco alloys txhawm rau ua kom lub zog deformation thiab hloov pauv lub zog siv los ntawm kev deformation ntawm Nitinol cov duab nco alloys, tiv thaiv kev sib kis ntawm cov qauv seismic zog rau cov qauv sab saud, yog li tiv thaiv cov qauv sab saud thiab txhim kho tiag tiag. seismic kev ua tau zoo ntawm cov qauv.
(3) Aerospace kev lag luam
Nyob rau hauv lub dav hlau hydraulic system, yeej txhua lub dav hlau yuav tsum tau siv yim puas npib tsib xee-titanium alloy zoo nco alloy pob qij txha. Feem ntau US Navy aircraft tau siv qhov haum no txij li xyoo 1970s thiab tsis muaj ntaub ntawv ua tsis tiav. Tsis tas li ntawd, npib tsib xee-titanium alloy zoo li nco alloys kuj tseem siv tau rau hauv lub dav hlau kav hlau txais xov, electromechanical actuators, thiab lwm yam.
